The present inventive subject matter relates to chemical structures that define cells in which operating material can be held, as well as compositions that contain such chemical structures and operating material, compositions for use in making such compositions, and methods for making all of the above.
There is an ongoing need for materials (e.g., coatings and films) which have any of a variety of properties, including low adhesion, anti-fogging capabilities, fluid repellent capabilities, and self-cleaning capabilities, for use, e.g., in making a wide variety of products, e.g., as diverse as windows, sensors, biomedical devices and lenses. There is a need for materials that have excellent release properties, and that can be used to make a wide variety of products, e.g., molds, transfer films, industrial tapes, labels, die-cut constructions, double-sided tapes, silicone foam or rubber tapes, in-process liners for easier handling of jumbo rolls, transfer to heat sensitive or non-solvent-castable backings, and non-adhesion lab and medical devices. There is also a need for materials (e.g., coatings) that have anti-stain capabilities, and/or anti-fingerprint capabilities, for use in making a wide variety of products, e.g., touch screens, small and large appliance bodies and working surfaces. There is also a need for materials that can provide excellent ice release on wind turbines, power lines, building drip edges, fishing lines, and aircraft wings. There is also a need for materials that are effective as adhesives, including pressure-sensitive adhesives.
Polymers are large molecules (in most cases) with physical properties that depend on the interactions between the polymer chains. An important factor in these interactions is the topology of chains making up the backbone of the molecule.
Some polymer molecules are linear, similar to normal alkanes, such as n-decane. An example of a linear polymer is high density polyethylene (HDPE), which can contain more than 1,000 CH2 groups. Polymers with very small pendant groups, such as the methyl group in polypropylene, are considered to be linear. Simulated skeletal and more detailed structures of HDPE are shown in
In many cases, linear polymers may form closely packed crystals, as figuratively shown in
Some polymers, such as low density polyethylene (LDPE), have branches of different sizes irregularly spaced along the chain. Such polymers are said to be branched or nonlinear.
The branches prevent the nonlinear molecules from packing as closely as the linear molecules, thus reducing their density. Simulated skeletal and more detailed structures of LDPE are shown in
Some polymers have cross-links between polymer chains, creating networks, and are called network polymers. Slightly cross-linked polymers are often elastomers, while highly cross-linked polymers may be rigid and hard. Cross-links may be formed by exposure to heat, light, moisture, and/or oxygen, or by other chemical reactions. A skeletal structure of a network polymer with a high cross-link density is illustrated in
In each of these cases, polymer topology also determines the degree to which additives and property modifiers may be taken up inside the structure. Crystalline linear polymers have almost no ability to hold slip agents and plasticizers inside their structure. Due to free space considerations, branched polymers may hold somewhat more. Depending on the degree of cross-linking, network polymers may hold considerably more of such liquid or solid agents than linear or branched polymers.
Of such agents, lubricants have been impregnated into materials for many centuries, when fats were soaked into fire-hardened axles and wheel races. Babbitt bearings are comprised of porous metals that absorb lubricants. Nylon 6,6 and PTFE bearings may contain liquid or solid lubricants that provide extended lubricity.
Shallow surface microstructures comprising oils were disclosed by Brown in U.S. Pat. No. 6,767,587. More recently, Aizenberg, et. al., disclosed in U.S. Pat. No. 9,630,224 surface structures to superficially retain lubricants and to provide reduced adhesion to ice and other substances. To the same end, Golovin, et. al., disclosed curing durable random network polymers comprising lubricants at modest levels of about 10 to 15 percent in PCT Publication No. WO 2016/176350 A1. Higher levels of lubricant may be expressed at the polymer surface.
In 1983, network polymers were disclosed by Von Au, et al., in U.S. Pat. No. 4,503,210, comprising components forming elastomers with the potential to form polymer crystalline lattices; however, the polymers were formed without essential ingredients and under conditions where such structures would never have formed. Much later, Miriani, et al., disclosed similar liquid rubber compositions in U.S. Pat. No. 9,528,005. These compositions comprised a novel solid filler. They also included low levels of silicone oils as plasticizers and diluents that would have been insufficient to form structures of the present invention.

Where an expression is defined herein in terms of the meaning of the expression in the singular, the definition applies also to the plural (and vice-versa, i.e., an expression defined herein in the plural, the definition applies also to the singular). Definitions of one form of an expression apply to the same expression in a different form of the word or words.
In some aspects, the present inventive subject matter relates to lattice structures, compositions that each comprise at least one lattice structure and one or more operating materials, compositions that each can be used in making one or more lattice structures (and/or in making a composition that comprises one or more lattice structures and one or more operating materials), and methods of making all of such things. The disclosure herein describes such lattice structures in terms of their chemical natures. In some aspects of the present inventive subject matter, the chemical nature of such lattice structures is described in terms of nuclear moieties and elongated moieties which are analogous to building blocks that can together build large chemical structures (i.e., lattices), with the nuclear moieties analogous to nodes and the elongated moieties analogous to connectors extending between nodes. In some aspects herein, the lattice structures are therefore described in terms of the nuclear moieties and the elongated moieties, and in some aspects, the nuclear moieties and the elongated moieties are described in terms of representative chemical compounds (nuclear moiety precursor compounds and elongated moiety precursor compounds) that can be reacted to generate the lattice structures (whereby the nuclear moieties “correspond” to respective nuclear moiety precursor compounds and are not identical to their respective corresponding nuclear moiety precursor compounds, and the elongated moieties “correspond” to respective elongated moiety precursor compounds and are not identical to their respective corresponding elongated moiety precursor compounds). The lattice structures in accordance with the present invention are not limited to products of specific reactants. In view of all of this, the expressions used herein to describe the subject matter within the various aspects of the present inventive subject matter are defined in detail below.
The expression “bonded,” as used herein, refers to any type of chemical bonding, including ionic bonding, metallic bonding, van der Waals forces, covalent bonding, hydrogen bonding, etc. The expression “bond,” as used herein, refers to any bond (an ionic bond, a metallic bond, a van der Waals force, a covalent bond, a hydrogen bond, etc.), between two atoms. Thus, the expression “bond” (and the expression “chemical bond”), as used herein, refers to a lasting affinity between atoms, ions or molecules that enables the formation of chemical compounds and moieties. A bond may result from the electrostatic force of attraction between oppositely charged ions, as in ionic bonds, or through the sharing of electrons, as in covalent and metallic bonds. There are strong or primary bonds, such as metallic, covalent or ionic bonds, and weak or secondary bonds, such as dipole-dipole interactions, the London dispersion force and hydrogen bonding.
The expression “directly bonded”, as used herein (e.g., in the expression “directly bonded to one or more resultant elongated moieties”), means that one or more bond extends from [1] an entity (the “first entity”, which is an atom or a moiety), to [2] another entity (the “second entity”, also an atom or a moiety) to which the first entity is directly bonded, i.e, there are no intervening atoms between the first entity and the second entity. A statement that a first moiety is “directly bonded” to a second moiety means that at least one atom in the first moiety is directly bonded to at least one atom in the second moiety. A statement that a moiety is “directly bonded” to an atom (or a statement that an atom is “directly bonded” to a moiety) means that the atom is directly bonded to at least one atom in the moiety.
The expression “indirectly bonded”, as used herein (e.g., a first entity (an atom or a moiety) is “indirectly bonded” to a second entity (an atom or a moiety) means that the first entity is not directly bonded to the second entity, but the first entity is bonded to the second entity via one or more intervening atoms, i.e., starting from the first entity, a path can be traced to the second entity via atoms and atom-to-atom bonds (each such atom-to-atom bond connecting one respective atom to another respective atom).
The expression “chemical compound,” as used herein, (as well as the expression “compound,” as used herein) refers to an arrangement of atoms that are each bonded (by ionic bonding, metallic bonding, van der Waals force, covalent bonding, and/or hydrogen bonding), directly (i.e., with no intervening atoms) or indirectly (i.e., via one or more other atoms), to each other atom in the chemical compound.
The expression “moiety” (e.g., “nuclear moieties” and “elongated moieties”), as used herein, refers to an arrangement of atoms that are each bonded (by ionic bonding, metallic bonding, van der Waals force, covalent bonding, and/or hydrogen bonding), directly (i.e., with no intervening atoms) or indirectly (i.e., via one or more other atoms), to each other atom in the moiety. A “moiety,” as used herein, consists of some or all of the atoms in a chemical compound, and the bonds that connect each of the atoms in the moiety to one or more other atom(s) in the moiety.
The expression “chemical structure,” as used herein, refers to an arrangement of atoms and bonds (e.g., ionic bonds, metallic bonds, van der Waals forces, covalent bonds, hydrogen bonds, etc.) in a compound or a moiety, i.e., precisely which atoms are bonded to what other atoms, and the nature of each of such bonds.
A “chemical structure” can thus refer to an arrangement of actual atoms and bonds (i.e., a single specific compound or portion of a compound), or can refer generically to any arrangement of atoms and bonds that has all of the features specified for the chemical structure (i.e., any compound or portion of a compound that has the specified arrangement of atoms and bonds, e.g., any ethyl group). As an example where “chemical structure” refers to an actual arrangement, one might describe an actual reaction by saying that “two grams of [a first compound] were mixed in a beaker with two grams of [a second compound], and the first and second compounds underwent a chemical reaction to form a third compound, the third compound comprising [1] a moiety that corresponds to a moiety in the first compound, and [2] a moiety that corresponds to a moiety in the second compound. As an example where a “chemical structure” refers generically to any arrangement of atoms and bonds that has all of the features specified for the chemical structure, one might state that in order to form the third compound, one can react a quantity of the first compound with a quantity of the second compound under specific conditions and/or in the presence of one or more other materials. Moreover, one might analyze a chemical compound and determine that the chemical compound comprises a moiety that has a particular chemical structure (i.e., without knowledge as to the exact way by which the chemical compound came to exist, e.g., whether it resulted from a reaction involving any chemical compound that comprises the entirety of the chemical structure).
The expression “chemical structure” thus encompasses [1] chemical structures that refer to all of the atoms that are bonded together (and the bonds among such atoms), i.e., “chemical compounds” (or “compounds”), as well as [2] chemical structures that together make up a subset of the atoms that are bonded together (and the bonds among such subset of atoms). For example, a moiety that is part of a chemical compound has a chemical structure, and the entire chemical compound (of which the moiety is a part) comprises the moiety but has a different overall chemical structure.
The expression “chemical structure in a compound,” as used herein, can refer to [1] the entirety of the compound, or [2] a portion of the compound. Thus, a statement herein that a chemical structure is “in a compound” means that the compound comprises the chemical structure, and can have an overall chemical structure that differs from the chemical structure (in that it comprises one or more additional atoms and/or bonds).
The expression “chemical structure,” as used herein, does not necessarily refer to geometrical characteristics, i.e., a “chemical structure” in a moiety can be the same as a “chemical structure” in a compound, even though geometrical characteristics of the chemical structure in the moiety may differ from geometrical characteristics of the chemical structure in the compound.
The expression “lattice structure,” as used herein, refers to a three-dimensional arrangement of chemical moieties (including but not limited to instances in which the chemical moieties together make up a somewhat repeating arrangement, e.g., to form a cubic lattice, a tetrahedral lattice or any Bravais lattice), each chemical moiety comprising an arrangement of atoms, to provide a crystalline, semi-crystalline and/or quasi-crystalline arrangement. For example, in some aspects, the present inventive subject matter relates to lattice structures that each comprise a plurality of nuclear moieties and a plurality of elongated moieties, with some or all of the nuclear moieties bonded (by ionic bonding, metallic bonding, van der Waals force, covalent bonding, and/or hydrogen bonding) to at least three elongated moieties, and some or all of the elongated moieties bonded (by ionic bonding, metallic bonding, van der Waals force, covalent bonding, and/or hydrogen bonding) to at least two nuclear moieties.
The expression “nuclear moiety,” as used herein, refers to a moiety that is bonded (by ionic bonding, metallic bonding, van der Waals force, covalent bonding, and/or hydrogen bonding) to at least three respective elongated moieties. The term “nuclear” is not intended to specify any particular atomic or chemical feature, and does not characterize a moiety in any particular way, except that a nuclear moiety is selected from among the arrangements of atoms that are characterized herein as nuclear moieties.
The expression “nuclear moiety precursor compound,” as used herein, refers to a chemical compound that comprises at least part of a nuclear moiety (a nuclear moiety consists of or comprises a chemical structure that is the same as at least part of a chemical structure in a corresponding nuclear moiety precursor compound, and/or in which atoms are re-arranged). A nuclear moiety precursor compound may contain one or more additional atoms, and/or one or more fewer atoms, and/or one or more atoms may be substituted for, in comparison to a “corresponding” nuclear moiety.
The expression “plurality of nuclear moiety precursor compounds,” as used herein, refers to two or more chemical compounds (nuclear moiety precursor compounds) that are the same or different (i.e., a “plurality of nuclear moiety precursor compounds” can consist of a plurality of compounds of the same chemical structure, or can comprise any respective numbers of compounds of each of two or more chemical structures).
The expression “elongated moiety,” as used herein, refers to a moiety that is bonded (by ionic bonding, metallic bonding, van der Waals force, covalent bonding, and/or hydrogen bonding) to at least two respective nuclear moieties. The term “elongated” is not intended to specify any particular or generic geometrical feature, and does not characterize a moiety in any particular way, except that an elongated moiety is selected from among the arrangements of atoms that are characterized herein as elongated moieties.
The expression “elongated moiety precursor compound,” as used herein, refers to a chemical compound that comprises at least part of an elongated moiety (an elongated moiety consists of or comprises a chemical structure that is the same as a chemical structure in a corresponding elongated moiety precursor compound, and/or in which atoms are re-arranged).
An elongated moiety precursor compound may contain one or more additional atoms, and/or one or more fewer atoms, and/or one or more atoms may be substituted for, in comparison to a “corresponding” elongated moiety.
The expression “plurality of elongated moiety precursor compounds,” as used herein, refers to two or more chemical compounds (elongated moiety precursor compounds) that are the same or different (i.e., a “plurality of elongated moiety precursor compounds” can consist of a plurality of compounds of the same chemical structure, or can comprise any respective numbers of compounds of each of two or more chemical structures).
The expression “functional moiety” is used herein (with regard to a nuclear moiety precursor compound or an elongated moiety precursor compound) in accordance with its well known meaning to refer to a moiety (or functional group) that is among the many moieties that are recognized and classified as groups of bonded atoms. In particular, the expression “functional moiety” is used herein to refer to a moiety (e.g., a portion of a nuclear moiety precursor compound or a portion of an elongated moiety precursor compound) that is known to readily undergo chemical reaction with one or more specific other functional moieties (or any of a range of moieties).
The expression “bonded-functional moiety” is used herein (with regard to a nuclear moiety or an elongated moiety) to refer to the portion of a functional moiety that corresponds to a functional moiety, e.g., the portion from a functional moiety that remains (in a nuclear moiety or an elongated moiety) after a reaction between a nuclear moiety precursor compound and an elongated moiety precursor compound (i.e., a reaction that results in an atom of the nuclear moiety precursor compound becoming bonded to an atom of the elongated moiety precursor compound).
The expression “corresponds” (and the related expression “corresponding”), as used herein, refers to a comparison between [1] a first chemical structure consisting of specific atoms (namely, a chemical compound or a moiety), and [2] a second chemical structure (namely, a moiety), in which at least a portion of the first chemical structure [i] is the same as the entirety of the second chemical structure, or [ii] differs from the second chemical structure by the removal or one or more atoms, and/or the addition of one or more atoms, and/or the re-arrangement of one or more atoms, and/or the conversion of one or more bonds to a respective different bond (e.g., conversion of a double bond to a single bond). Some or all of the atoms in the second chemical structure can be the same individual atoms (i.e., actual atoms) as those in the first chemical structure, or merely an analogous arrangement of atoms and bonds in the second chemical structure can be in the first chemical structure (i.e., none of the atoms in the first and second chemical structures are the same individual atoms, but instead some or all of the atoms in the second chemical structure are the same elements, arranged in the same way, as the elements in at least a portion of the first chemical structure, e.g., if the second chemical structure is characterized as any ethyl group and the first chemical structure is characterized as any ethane compound).
As an example of the atoms in the second chemical structure being the same individual actual atoms (arranged in the same way) as those in the first chemical structure, where a “precursor compound” is involved in a chemical reaction (actual or theoretical, i.e., the same individual atoms or the same generic arrangement of atoms) that results in a product (or that would result in a product), such that the product contains a “resultant moiety” that consists of atoms that were in the precursor compound, the precursor compound “corresponds” to the resultant moiety, and the resultant moiety “corresponds” to the precursor compound; in addition, [1] the precursor compound is characterized as “a corresponding precursor compound” relative to the resultant moiety, and [2] the resultant moiety is characterized as “a corresponding resultant moiety” relative to the precursor compound. As noted above, the terminology herein relates to actual chemical structures as well as to generic chemical structures, and so the expressions “precursor” and “resultant” are used in an actual sense or in a generic sense, and are used to define chemical structures, not to imply that a resultant chemical structure must have actually resulted from a reaction involving the precursor chemical structure. In the example set forth earlier in this paragraph, since the atoms in the resultant moiety (second chemical structure) are the same atoms (arranged in the same way) as those in the precursor compound (first chemical structure), the precursor compound also “corresponds directly” to the resultant moiety, and the resultant moiety “corresponds directly” to the precursor compound; also [1] the precursor compound can further be characterized as “a directly corresponding precursor compound” relative to the resultant moiety, and [2] the resultant moiety can further be characterized as “a directly corresponding resultant moiety” relative to the precursor compound. That is, a second chemical structure and a first chemical structure “directly correspond” if the second chemical structure differs from the first chemical structure only by the removal of one or more atom(s) from the first chemical structure, and/or by the conversion of one or more bonds (e.g., from a double bond to a single bond), and/or by the re-arrangement of atoms. If on the other hand, the second chemical structure differs from the first chemical structure by the addition of one or more atoms to the first chemical structure, and/or the substitution of one or more atoms in the first chemical structure (optionally in addition to the “directly” corresponding changes, i.e., removal of one or more atom(s) from the first chemical structure, and/or conversion of one or more bonds (e.g., from a double bond to a single bond), and/or re-arrangement of atoms), the precursor compound “corresponds indirectly” to the resultant moiety; the resultant moiety “corresponds indirectly” to the precursor compound; the precursor compound can be characterized as “an indirectly corresponding precursor compound” relative to the resultant moiety, and the resultant moiety can be characterized as “an indirectly corresponding resultant moiety” relative to the precursor compound.
As an example of merely the arrangement of atoms and bonds in the second chemical structure being in the first chemical structure (i.e., as a result of a theoretical reaction, with the chemical structures described in a generic sense), where a second structure consists of an ethyl group, such second structure corresponds to any ethane compound (because each comprises two carbon atoms and five hydrogen atoms bonded in similar ways). Thus, for example, the expression “nuclear moiety corresponds to a compound selected from among [a group of chemical compounds]”), as used herein, means that the nuclear moiety, in its entirety, consists of a chemical structure [a] that is identical to a chemical structure in a portion (or an entirety) of one of the chemical compounds in the recited group of chemical compounds, or [b] differs from a chemical structure in a portion (or an entirety) of one of the chemical compounds in the recited group of chemical compounds in one or more of the other ways described above (and the expression “[a chemical compound] corresponds to a nuclear moiety” means that a chemical structure in the compound [a] is identical to the nuclear moiety), or [b] differs from the nuclear moiety in one or more of the other ways described above; an example of where the expression “nuclear moiety directly corresponds to a compound selected from among [a group of chemical compounds]” (and the expression “[a chemical compound] corresponds to a nuclear moiety”) would apply herein is where the nuclear moiety, in its entirety, consists of a chemical structure that is identical to a chemical structure in a portion (or an entirety) of one of the chemical compounds in the recited group of chemical compounds.
Thus, for example, where a nuclear moiety, in its entirety, consists of a chemical structure that is identical to a chemical structure in a portion (or an entirety) of one of the chemical compounds in a recited group of chemical compounds, the expression “nuclear moiety directly corresponds to a compound selected from among [a group of chemical compounds]”) would apply.
In accordance with the terminology employed in the present specification, a plurality of chemical compounds (comprising a plurality of nuclear moiety precursor compounds and a plurality of elongated moiety precursor compounds) can be reacted to result in a lattice structure that comprises [1] a plurality of resultant nuclear moieties that correspond to respective nuclear moiety precursor compounds, and [2] a plurality of resultant elongated moieties that correspond to respective elongated moiety precursor compounds. Accordingly, in the present specification, a “corresponding resultant nuclear moiety” (with respect to a nuclear moiety precursor compound) refers to a nuclear moiety which [1] directly corresponds to the nuclear moiety precursor compound or indirectly corresponds to the nuclear moiety precursor compound, and [2] is included in the lattice structure. Similarly, a resultant nuclear moiety that “corresponds to a nuclear moiety precursor compound” refers to a nuclear moiety which [1] directly corresponds to the nuclear moiety precursor compound or indirectly corresponds to the nuclear moiety precursor compound, and [2] is included in the lattice structure. Thus, in many cases, a resultant nuclear moiety differs from its “directly corresponding” nuclear moiety precursor compound, i.e., the nuclear moiety precursor compound to which it “directly corresponds” by the absence (e.g., by removal during a chemical reaction) of one or more atoms and/or the conversion of one or more double bonds to one or more respective single bonds and/or the conversion of one or more triple bonds to one or more respective double bonds, as well as being directly bonded to one or more resultant elongated moieties). Thus, in some instances, a resultant nuclear moiety consists of some or all of the atoms in its corresponding nuclear moiety precursor compound, and a resultant elongated moiety consists of some or all of the atoms in its corresponding elongated moiety precursor compound.
Likewise, a “corresponding nuclear moiety precursor compound” with respect to a resultant nuclear moiety, refers to the nuclear moiety precursor compound to which the resultant nuclear moiety (which is included in a lattice structure) corresponds (e.g., the nuclear moiety precursor compound that included the atoms, some or all of which are in the resultant nuclear moiety). Similarly, a “nuclear moiety precursor compound that corresponds to a resultant nuclear moiety” refers to the nuclear moiety precursor compound to which the resultant nuclear moiety (which is included in a lattice structure) corresponds.
The definitions in the preceding four paragraphs apply similarly with respect to elongated moiety precursor compounds and resultant elongated moieties (i.e., the preceding four paragraphs, with each occurrence of “nuclear” being replaced by “elongated,” also are applicable in the present specification).
In accordance with the terminology employed in the present specification, a plurality of chemical compounds (comprising a plurality of nuclear moiety precursor compounds and a plurality of elongated moiety precursor compounds) can be reacted to result in a lattice structure that comprises [1] a plurality of nuclear moieties that correspond (respectively) to the nuclear moiety precursor compounds, and [2] a plurality of elongated moieties that correspond (respectively) to the elongated moiety precursor compounds.
For example, in some cases where a plurality of actual nuclear moiety precursor compounds and a plurality of actual elongated moiety precursor compounds react with each other by condensation reactions (i.e., each reaction proceeding in a step-wise fashion to produce a product, usually in equilibrium and with the release of water, ammonia, ethanol, acetic acid, or other such species, and typically proceeding in acidic or basic conditions and/or in the presence of a catalyst):
In, some situations where a plurality of actual nuclear moiety precursor compounds and a plurality of actual elongated moiety precursor compounds react with each other by addition reactions (i.e., where two or more molecules combine to form a larger one (the adduct) and involve compounds having multiple bonds, as examples, molecules with carbon-carbon double bonds (alkenes) or with triple bonds (alkynes), hetero double bonds like carbonyl (C═O) groups, or imine (C═N) groups, and where such reactions can be electrophilic addition (polar) reactions, nucleophilic addition (polar) reactions, free-radical (non-polar) addition reactions and/or cycloaddition (non-polar) reactions):
The expression “nuclear moiety precursor compound functional moiety,” as used herein, refers to a functional moiety in a nuclear moiety precursor compound.
The expression “nuclear moiety bonded-functional moiety,” as used herein, refers to a chemical structure (in a nuclear moiety) that corresponds to a nuclear moiety precursor compound functional moiety of a nuclear moiety precursor compound that corresponds to the nuclear moiety.
The expression “elongated moiety precursor compound functional moiety,” as used herein, refers to a functional moiety in an elongated moiety precursor compound.
The expression “elongated moiety bonded-functional moiety,” as used herein, refers to a chemical structure (in an elongated moiety) that corresponds to an elongated moiety precursor compound functional moiety of an elongated moiety precursor compound that corresponds to the elongated moiety.
Respective functional moieties in nuclear moiety precursor compounds are capable of reacting with respective functional moieties in elongated moiety precursor compounds, and for each reaction between [1] a nuclear moiety precursor compound, and [2] an elongated moiety precursor compound, such that a chemical bond is formed (or chemical bonds are formed) between the corresponding nuclear moiety and the corresponding elongated moiety, [a] one or more atoms and/or bonds that was/were in the nuclear moiety precursor compound, and/or [b] one or more atoms and/or bonds that was/were in the elongated moiety precursor compound, is/are not included in the resulting lattice structure (and in some instances, the lattice structure can include atoms and/or bonds that were not in the nuclear moiety precursor compound or the elongated moiety precursor compound). In other words, a “lattice structure” does not comprise the entireties (i.e., all of the atoms and all of the bonds) of each of the respective chemical compounds that are reacted to form the lattice structure, and in the terminology used in the present specification, “elongated moieties” and “nuclear moieties” encompass those atoms, from their respective precursor chemical compounds (or moieties), that remain after actual reaction (or that would remain after a theoretical reaction, in the generic sense) to form a lattice structure (i.e., that are in the lattice structure). Similarly, in the terminology used herein, for each reaction between [1] a nuclear moiety precursor compound, and [2] an elongated moiety precursor compound, such that a chemical bond is formed (or chemical bonds are formed) between the corresponding nuclear moiety and the corresponding elongated moiety, [a] one or more atoms and/or bonds that was/were in the nuclear moiety precursor compound functional moiety, and/or [b] one or more atoms and/or bonds that was/were in the elongated moiety precursor compound functional moiety, is/are not included in the resulting lattice structure (and thus is/are not included in the resulting nuclear moiety bonded-functional moiety and/or the resulting elongated moiety bonded-functional moiety, i.e., the difference between “functional moiety” and “bonded-functional moiety” is that a “functional moiety” (in a nuclear moiety precursor compound or an elongated moiety precursor compound) is a reactive moiety, whereas a “bonded-functional moiety” (in a nuclear moiety or an elongated moiety) is what remains of the functional moiety after reaction). As described above, lattice structures are described herein generically, in terms of chemical structures, including descriptions of moieties that correspond to compounds (nuclear moiety precursor compounds or elongated moiety precursor compounds) and/or that correspond to moieties or functional moieties of such compounds, i.e., without implying that the lattice structures necessarily resulted from actual reaction of specified compounds or moieties.
Statements herein that each of a plurality of moieties “correspond” to a respective one of a group of compounds means that each individual moiety corresponds to some member of the group, i.e., each of the moieties can correspond to the same chemical structure, or any respective numbers of the moieties can correspond to each of two or more chemical structures (e.g., some of the moieties are of a first chemical structure, some of the moieties are of a second chemical structure, and some of the moieties are of a third chemical structure). For example, the expression “each of the plurality of nuclear moieties corresponding to one of the nuclear moiety precursor compounds,” as used herein, indicates that any number of the nuclear moieties can be of the same chemical structure or of different chemical structures, and [1] each nuclear moiety corresponds (as defined above) to a respective actual nuclear moiety precursor compound, or [2] each nuclear moiety corresponds to one of the chemical structures within the scope of the nuclear moiety precursor compounds (and analogously, the expression “each of the plurality of elongated moieties corresponding to one of the elongated moiety precursor compounds,” as used herein, indicates that any number of the elongated moieties can be of the same chemical structure or of different chemical structures, and [1] each elongated moiety corresponds (as defined above) to a respective actual elongated moiety precursor compound, or [2] each elongated moiety corresponds to one of the chemical structures within the scope of the elongated moiety precursor compounds).
Thus, a statement herein that “each of the nuclear moieties corresponds to a respective compound selected from among the group consisting of [a group of compounds],” means that each of the nuclear moieties can correspond to the same chemical compound, or that respective numbers of the nuclear moieties can correspond to each of two or more chemical structures, e.g., some are of a first chemical structure, some are of a second chemical structure, and some are of a third chemical structure (and similarly with respect to other analogous statements, e.g., “each of the elongated moieties corresponds to a respective compound selected from among the group consisting of [a group of compounds]”).
A statement herein that “each of the nuclear moiety precursor compounds is selected from among the group consisting of [a group of compounds],” means that the respective nuclear moiety precursor compounds can all be the same type of compound, or that respective numbers of the nuclear moiety precursor compounds can be of each of two or more chemical structures (and similarly with respect to other analogous statements, e.g., “each of the elongated moiety precursor compounds is selected from among the group consisting of [a group of compounds]”).
A statement herein that “each of the nuclear moieties comprises at least one nuclear moiety bonded-functional moiety selected from among the group consisting of [a group of moieties]” means that each of such nuclear moieties comprises one or more nuclear moiety bonded-functional moieties, and where a nuclear moiety comprises two or more nuclear moiety bonded-functional moieties, each of the bonded-functional moieties may be the same, each of the bonded-functional moieties may differ, or any number of the bonded-functional moieties may be respective different nuclear moiety bonded-functional moieties (and similarly with respect to other analogous statements, e.g., “each of the nuclear moiety precursor compounds comprises at least one nuclear moiety precursor compound functional moiety selected from among the group consisting of [a group of functional moieties]”, “each of the elongated moieties comprises at least one elongated moiety bonded-functional moiety selected from among the group consisting of [a group of bonded-functional moieties]”. “each of the elongated moiety precursor compounds comprises at least one elongated moiety precursor compound functional moiety selected from among the group consisting of [a group of functional moieties], etc.”).
The expression “cell defined by respective atoms of the lattice structure,” as used herein, refers to a region [1] that is within a lattice structure (as defined herein), and [2] does not include any atom of a nuclear moiety or any atom of an elongated moiety. The expression “operating material compound within a cell” (and similar or analogous expressions), as used herein, refers to one or more operating material compounds in such a region within a lattice structure.
The expression “plurality of operating material compounds,” as used herein, means at least two chemical compounds which are each among the types of chemical compounds from which operating materials can be selected, and [1] are each of the same chemical structure, or [2] any respective quantities are of each of two or more different chemical structures.
The expression “operating material compounds,” as used herein (e.g., in the expression “supplying at least [1] nuclear moiety precursor compounds, [2] elongated moiety precursor compounds, and [3] operating material compounds to a space,” or the expression “removing from the space a composition comprising at least a first lattice structure and a plurality of said operating material compounds,” or the expression “at least some of said operating material compounds are in respective cells of the first lattice structure” can refer to two or more chemical compounds which [1] are each of the same chemical structure, or [2] any respective quantities are of each of two or more different chemical structures (e.g., [1] the operating material compounds are all of the same chemical structure, or [2] the operating material compounds comprise a mixture consisting of two parts by weight of a first chemical structure, three parts by weight of a second chemical structure and five parts by weight of a third chemical structure, etc.).
The expression “one or more operating material compounds” means a single operating material compound or a plurality of operating material compounds [1] which are each of the same chemical structure, or [2] which comprise any respective quantities are of each of two or more different chemical structures.
The expression “plurality of operating material compounds within respective cells defined by the lattice structure,” as used herein, means that [1] each of the plurality of operating material chemical compounds is within a respective cell defined by the lattice structure (i.e., each of the plurality of operating material compounds is in a different cell), or [2] any number of the operating material compounds are in at least one of the cells.
The operating material or plurality of operating materials effect formation of the lattice structure, as is often the case in the formation of ordinary crystalline lattice structures. In the present inventive subject matter, at least one operating material is retained in the crystalline structure.
The expression “supplying [respective compounds] to a space,” e.g., the expression “supplying [1] nuclear moiety precursor compounds, [2] elongated moiety precursor compounds, and [3] operating material compounds to a space,” as used herein, encompasses any activity (or combination of activities) by which at least some of the respective compounds can come into contact with each other (and does not require any degree of stirring, shaking, blending and/or other activity that would increase uniformity of dispersion of any or all compounds among any other compounds). Representative examples include (and are not limited to) supplying (intermittently or continuously, or any combination thereof, at any rate, in batches or all at once) respective compounds (all compounds at the same time, all or part of individual respective compounds in any sequence, respective portions (or batches) of respective compounds in any order and/or any portions simultaneously, etc.) to a container, a reaction chamber, etc.
The expression “accounts for at least [a particular] weight percent,” as used herein (e.g., in the expression “wherein the operating material accounts for at least 40 weight percent of the composition”) means that the composition comprises at least the specified weight percent of the specified material (e.g., operating material) among the entire composition (i.e., at least the specified percentage of the composition is the specified material, e.g., the expression “wherein the operating material accounts for at least 40 weight percent of the composition” means that at least 40 weight percent of the composition is operating material).
In some aspects, the present inventive subject matter relates to three-dimensional polymer lattice structures (crystalline, semi-crystalline or quasi-crystalline), which are capable of holding operating material (e.g., at least 20 percent by weight, at least 30 percent by weight, at least 40 percent by weight, at least 50 percent by weight), and that are capable of holding at least some of such operating material (e.g., 70 percent of such operating material, 80 percent of such operating material, 90 percent of such operating material) at least for some period of time, and preferably for long periods of time, e.g., at least one month.

In some embodiments according to the present inventive subject matter, including some embodiments that include or do not include any of the features as discussed herein, preferred lattice structures in accordance with the present inventive subject matter have geometry or topology selected from among tetrahedral lattices and cubic lattices.
In many methods of forming organic crystals and many methods of forming inorganic crystal formation, solvents or combinations of solvents are often used to allow elements of the crystal to orient and form bonds, whether covalent, ionic, metallic, hydrogen or Van der walls. Such solvents are typically slowly evaporated after crystallization begins, to encourage further crystallization. When crystallization is complete, solvents are typically removed entirely. In many such cases, without the solvent, or with too much solvent, little crystallization would occur. As discussed below, in the present invention, the operating material(s) assist in, facilitate and/or provide for reactions that generate a lattice structure as described herein. In some cases, one or more solvents can be used in addition to operating material(s).
In some embodiments of methods of making a composition comprising a lattice structure and an operating material in accordance with the present inventive subject matter, including some embodiments that include or do not include any of the features as discussed herein, as with the above-mentioned methods of forming organic crystals and methods of forming inorganic crystals, operating material(s), acting as a solvent, is used at a concentration where crystallization is favored during the bonding of nuclear and elongation elements. In some embodiments of methods of making a composition comprising a lattice structure and an operating material in accordance with the present inventive subject matter, including some embodiments that include or do not include any of the features as discussed herein, the concentration of solvent is sufficiently low to form a lattice structure in which operating material is completely captured inside the lattice, with little or no operating material expressed at any exterior surface of the lattice structure.
In some embodiments of methods of making a composition comprising a lattice structure and an operating material in accordance with the present inventive subject matter, including some embodiments that include or do not include any of the features as discussed herein, concentration of the operating material is in the range of from about 30 percent to about 50 percent per by weight of the entire composition (i.e., the composition for generating a composition comprising a lattice structure and operating material). In some embodiments of methods of making a composition comprising a lattice structure and an operating material in accordance with the present inventive subject matter, including some embodiments that include or do not include any of the features as discussed herein, the concentration of the operating material is chosen with consideration of the length of the elongation moieties (or the respective lengths of the elongation moieties). For example, In some embodiments of methods of making a composition comprising a lattice structure and an operating material in accordance with the present inventive subject matter, including some embodiments that include or do not include any of the features as discussed herein, at least some of the elongation moieties are of a length of about 2500 amu, a weight percentage of operating material in the composition for generating a composition comprising a lattice structure and operating material is in the range of from about 50 percent to about 60 percent by weight, resulting in there being no observable operating material excess at any surface of the lattice structure generated. In some embodiments of methods of making a composition comprising a lattice structure and an operating material in accordance with the present inventive subject matter, including some embodiments that include or do not include any of the features as discussed herein, where a significant proportion of the elongated moieties are branched or network polymers, a weight percentage of operating material in the composition for generating a composition comprising a lattice structure and an operating material is in the range of from only a few percent to only about 15 percent.
In some aspects of the present inventive subject matter, there are provided lattice structures that are able to hold large amounts of operating material, and that are able to hold large amounts of operating material without accumulating significant quantities of excess operating material at any surface of the lattice structure (e.g., with substantially no operating material at any surface of the lattice structure), including lattice structures that are able to hold amounts of operating material that exceed amounts of operating material held in prior art structures, and/or with accumulating less operating material at surfaces of the lattice structure than in such prior art structures.
Without being bound to any particular theory, the applicant believes that the ability of the lattice structures in accordance with the present inventive subject matter to hold larger amounts of operating material, and to do so with lower quantities of operating material accumulating at surfaces of the lattice structure, results at least in part from the very high (higher than that of prior art structures) structural integrity of the lattice structures in accordance with the present inventive subject matter. Moreover, even at the high operating material loads achieved by lattice structures in accordance with the present inventive subject matter, the strength, toughness and abrasion resistance of the operating material-containing lattice structures in accordance with the present inventive subject matter remain high, in some instances nearly equal to similar to compositions that do not comprise an operating material (or that comprise a much lower amount of operating material).
In some embodiments according to the present inventive subject matter, including some embodiments that include or do not include any of the features as discussed herein, there are provided lattice structures that comprise one or more coatings (over part of all of the lattice structure). Such coatings can comprise, e.g., adhesion promoters, surfactants, surface modifiers, and/or monomers that impart useful properties.
Applications for crystalline polymer lattices comprising operating materials cover a very broad range, where they can be superior to conventional coatings and films in cost and/or performance; in terms of low adhesion, they are greatly superior. Anti-fogging, fluid repellent, and self-cleaning coatings, according to the present invention, can be made for windows, sensors, biomedical devices and lenses. The remarkable release properties of some embodiments of the present invention can be useful for molds, transfer films, industrial tapes, labels, die-cut constructions, double-sided tapes, silicone foam or rubber tapes, in-process liner for easier handling of jumbo rolls, transfer to heat sensitive or non-solvent-castable backings, and non-adhesion lab and med devices. Anti-stain, anti-fingerprint coatings of the present invention can have advantages for touch screens, small and large appliance bodies and working surfaces. Ice release on wind turbines, power lines, building drip edges, and aircraft wings can be improved by the present invention. In still other embodiments, the operating material-filled crystal lattices of the present invention can be adhesives, including pressure-sensitive adhesives. Embodiments of the present invention can be hydrophoibic, lipophobic and superhydrophobic.
Conventional fluoro-trimethoxysilanes (Rf—Si(—O—CH3)3) typically require either months at ambient temperatures, or 30 minutes at 150 degrees C., to fully moisture cure. R—Si(-oxime)3 compounds on the other hand moisture cure at ambient temperatures in less than 24 hours, and can accelerate the cure of other silanes.
Properties of the operating material-containing lattice surfaces are affected by properties of the lattice structures and the operating material(s).
In Example 1, a stoichiometric mixture comprising [1] 2500 amu silane terminated polypropylene glycol (as elongated moiety precursor compounds), [2] silanetetrayltetraoxime (as nuclear moiety precursor compounds), and [3] operating material comprising 50 weight percent (w/w based on the total mixture) of diisononyl phthalate was formed. One mm thick films on glass plates were cured at 70° C. and 40% RH for 48 hours to form an operating material-containing lattice structure composition comprising a lattice structure with operating material held in cells of the lattice structure. Surfaces of the operating material-containing lattice structure were highly repellent to water and ice both before and after abrasion. Contact angles to water (of the operating material-containing lattice structure) were 85 to 95 degrees, and the slip angle to water (of the operating material-containing lattice structure) was 10 to 15 degrees. Adhesion to ice (of the operating material-containing lattice structure) was 0.5 to 4 KPa. Abrasion (of the operating material-containing lattice structure) was carried out on a 3000 grit belt at 2 inches per second with one kilogram pressure for 2000 inches of linear travel. This operating material-containing lattice structure was of course not resistant to organic solvents.
In Example 2, a stoichiometric mixture comprising [1] 2000 amu silane-terminated perfluoropolyether (as elongated moiety precursor compounds), [2] silanetetrayltetraoxime (as nuclear moiety precursor compounds), and [3] operating material comprising 50 weight percent (w/w based on the total mixture) of 4000 amu perfluoropolyether was formed. The mixture further comprised 10 weight percent of Vertrel™ MCA plus that evaporated during the cure. One mm thick films on glass plates were cured at 70° C. and 40% RH for 48 hours to form an operating material-containing lattice structure composition comprising a lattice structure with operating material held in cells of the lattice structure. Surfaces of the operating material-containing lattice structure were highly repellent to water and ice and a wide variety of organic solvents and oils both before and after abrasion. Contact angles to water (of the operating material-containing lattice structure) were 100 to 114, and contact angles to n-hexadecane (of the operating material-containing lattice structure) were 63 to 68 degrees. The slip angle to water (of the operating material-containing lattice structure) was 3 to 5 degrees. Adhesion to ice (of the operating material-containing lattice structure) was 0.2 to 4 KPa. Abrasion (of the operating material-containing lattice structure) was carried out on a 3000 grit belt at 2 inches per second with one kilogram pressure for 2000 inches of linear travel.
