Prior to 1988, all carbon-based polymers were exclusively classified as insulators. In fact, plastics have been used expensively in the electronics industry because of this very property. In 1979, Diaz and coworkers reported the conductive properties of polypyrrole. (Diaz, A. F., Kanazawa, K. K., and Gardini, G. P., Electrochemical Polymerization of Pyrrole, J Chem Soc Chem Commun, 635-6 (1979).) To date, numerous intrinsically conductive polymers or electroactive polymers have been developed. These polymers have versatile promising applications in the areas of electronic devices (Novak, P., Muller, K., Santhanam, K. S. V., and Haas, O., Electrochemically active polymers for rechargeable batteries, Chem Rev, 97, 207 (1997)), optical devices (Potember, R. S., Hoffman, R. C., Hu, H. S., Cocchiaro, J. E., Viands, C. A., Murphy, R. A., and Poehler, T. O., Conducting organics and polymers for electronic and optical devices, Polymer, 28, 574 (1987)), sensors (Nicholas, M., Fabre, B., and Simonet, J., Electrochemical Sensing of F− and Cl− with a Boric Ester-Functionalized Polypyrrole, J Electroanal Chem, 5091 (2001)), energy storage, medicine, and electrical infrastructure.
Intrinsically Conductive Polymers:
Intrinsically Conductive Polymers are polymeric organic compounds that exhibit the property of electrical conductivity. In general, these materials are either semiconductors or have metal conductivity. Conducting polymers have carbon backbones consisting of conjugated sp2 hybridized carbon bonds. One valence electron associated with each of these sp2 hybridized carbon atoms exists in a pz orbital orthogonally positioned relative to the three sigma bonds associated with the hybridized carbon atom. The electrons in these pz orbitals are termed delocalized and generally have high mobility when the material is “doped” by oxidation, a process that removes some of these delocalized electrons. Similarly, intrinsically conductive polymers can be created by the reduction of conjugated carbon backbones. In general, most conductive polymers are “doped” by oxidation to give “p-type” materials. This process is analogous to the doping of silicon semiconductors.
To date, these polymer preparations all suffer from the same drawbacks—poor processability and the lack of essential mechanical properties. In an attempt to address these limitations, efforts have been directed toward the production of composites of conducting polymer films and insulating polymers. For example, an insulating polymer, such as polycarbonate, is combined with a conducting polymer, such as polypyrrole, to produce conducting polymer composites that are conductive and have better mechanical functionality. (Wang, H. L., Toppare, L., and Fernandez, J. E., Conducting polymer blends: polythiophene and polypyrrole blends with polystyrene and poly(bisphenol A carbonate), Macromolecules, 23, 1053-9 (1990).)
Other insulating polymers used include poly(styrenesulphonate) (Otero, T. F., and Sansinena, J. M., Influence of synthesis conditions on polypyrrole-poly(styrenesulphonate) composite electroactivity, J Electroanal Chem, 412, 109-16 (1996)), poly(vinylchloride) (De Paoli, M. A., Waltman, R. J., Diaz, A. F., and Bargon, J, An electrically conductive plastic composite derived from polypyrrole and poly(vinylchloride), J Polym Sci Polym Chem Ed, 23, 1687-97 (1985)), nitrile rubber (Naoi, K., and Osaka, T., Highly enhanced anion doping-undoping process at the polypyrrole electrode of regulated morphology prepared with the aid of insulating NBR film, J Electrochem Soc Electrochem Sci Tech, 134, 2479-83 (1987)), polyimide (Iroh, J. O., and Levine, K., Electrochemical synthesis of polypyrrole/polyimide conducting composite using a polyamic acid precursor, Eur Polym J, 38, 1547-50 (2002)), and poly(vinyl alcohol) (Gangopadhyay, R., and De, A., Conducting polymer composites: novel materials for gas sensing. Sensors and Actuators B, 77, 326-9 (2001)). Other conducting polymers reported include polyaniline and polythiophene.
Energy storage devices have been reported that include an electrode composed of a conducting polymer and either a liquid or solid electrolyte. In solid state devices, a layer of electrolyte is sandwiched, either neet or impregnated in a matrix, between two electrodes. Performance of the storage devices is enhanced by electrochemically doping the conducting polymers with a dopant anion or cation. In these devices, the conducting polymer serves as the electronic conductor and the electrolyte matrix serves as the ionic conductor. The major drawback reported with these devices is the relatively low diffusion rate of the dopant ion into the polymer electrode, resulting in a high degree of internal resistance and a reduction in device performance.
Novel composites of an ionic conducting polymer and an electronic conducting polymer have also been reported (Berthier, C. M, Friend, R. H., Novel composites of an ionic conducting polymer and an electronic conducting polymer, U.S. Pat. No. 4,681,822.) These composites are composed of interpenetrating networks of a continuous electronic conducting material and a continuous ionic conducting material. Electronic conducting materials include polyacetylene, polyphenylene, polyphenyl diphenyl vinylene or a substituted polyacetylene, which are intimately mixed with a continuous ionic conducting material, defined as “a mixture of a complex of an ionic salt and a polymeric solvating agent such that the ionic conducting material has an increased melting point over its normal melting point.” The ionic salts used were limited to polyatomic anions, such as AsF6−, PF6−, BF4− and Cl4−, and alkali metal cations.
Additionally, in order to be effective, these ionic salts had to be mixed with a polymeric solvating agent, such as a polyalkylene oxide, capable of solvating the ionic salt. Additionally, the electronic conducting polymer must contain conjugated carbon-carbon double bonds capable of forming either “p-type” or “n-type” materials. The major advantage of these composites over the related conducting polymer/liquid-solid electrolyte devices is an increase in the ion diffusion rate of the dopant ion, and hence improved performance of the solid state energy storage device.
Nanoparticle Composites:
Numerous organic compound/metal nanoparticle composite conductive materials have been reported. Yang, et. at., reported the synthesis of polypyrrole/silver conducting nanotubes. (Yang, X., Li, L., Yan, F., Fabrication of Polypyrrole/Ag Composite Nanotubes via In Situ Reduction of AgNO3 on Polypyrrole Nanotubes, Chemistry Letters, 39(2): 118 (2009).) Meftah et. al., reported the synthesis of nickel nanoparticle/polyaniline composite films and their use in electronics, electrocatalystics, and optoelectronics. (Meftah, A. M., Saion, E., Abd, M., Mohd, M. B., Zainuddin, H. B., Absorbance of Nickel Nanoparticles/Polyaniline Composite Films Prepared by Radiation Technique, Solid State Science and Technology, 17(2), 167-174 (2009).)
Buttry in U.S. Patent Application 2009/0272949A1 discloses a method of producing metal oxide nanoparticles encapsulated with conducting polymers that are suitable for use as lithium ion battery cathodes or as catalytic materials. (Buttry, D. A., Method for Producing Metal Oxide Nanoparticles Encapsulated with Conducting Polymers, United States Patent Application Publication US 2009/0272949A2, 2009). Holliday in US Patent Application 2010/0038599A1 discloses compounds comprised of at least one semiconductor and/or photon absorber covalently linked to a conjugated conductive polymer. (Holliday, B. J., Polymerizable Semiconductors, Polymers Thereof, and Methods of Making and Using Same, United States Patent Application Publication US 2010/0038599A1, 2010). In all cases, and as seen with intrinsically conductive polymers, the polymers reported in these nanocomposite systems all contained either conjugated double bond systems or electron systems delocalized over several conjugated carbon atoms.
Metal-Containing Polymers
In 1979, Dawans and Morel reported, in U.S. Pat. No. 4,150,067, the development of organometallic polymers consisting of a backbone of saturated carbon atoms complexed to transition metal atoms. In order to obtain these organometallic materials, the polymers had to contain flurorcarboxylic acid groups, and the transition metals required ligand stabilization. As these inventors stated “ . . . there was an interest in the preparation of polymers including groups able to enhance the catalytic activity of the metal while maintaining said metal strongly bound to the polymeric carrier, in order to avoid that the catalytic complex be liberated in the medium during the reaction . . . . It has now been discovered that polymers containing the convenient fluorocarboxylic acid groups may be used as carriers for metal derivates and lead in particular to the formation of very active catalysts for various reactions.” (Dawans, F., Morel, D., Metal-Containing Polymers, Their Manufacture and Use, U.S. Pat. No. 4,150,067 (1979).) Thus, these inventors taught away from the concept that carboxylic acid groups alone could sufficiently bind metals strongly to the polymeric carrier, thereby avoiding liberation during subsequent reactions.
Use of 1-Octadecene, Polymer with 2,5 Furandione in Conducting Polymers:
Poly(ethylene oxide) (PEO) based solid polymer electrolytes have been widely reported due to the observation that the ethylene oxide units provide for the efficient solvation of metal cations. (Armand, M. B. In Polymer Electrolytes Review; McCallum, J. R., Vincent, C., Eds.; Elsevier Applied Science: London, 1987; Vol. 1, p 1; Gray, F. M. Polymer Electrolytes; The Royal Society of Chemistry: Cambridge, (1997). Due to the high crystallization aptitude of PEO, low conductivity of the salt complexes is observed at room temperature, thereby limiting its use in solid state electrochemical devices. To overcome this deficiency, poly(ethylene glycol) monomethyl ether (PEGME) has been grafted into the side chain of polymers such as polyacrylate and maleic anhydride copolymers. Tang and coworkers describe the synthesis and properties of multifunctional comb-like polymer electrolytes synthesized using poly(ethylene glycol) monomethyl ether (PEGME) as the metal-binding side chain and poly (maleic anhydride-alt-1-octadecene) (PMAO) as the backbone. (Tang, Z-l., Qi, L., Gao, G-t., Sun, M., Dong, S-j. Synthesis and Properties of Multifunctional Comblike Polymer Electrolytes, Journal of Functional Polymers, 21(1): 36-43, (2008).)
Saad and coworkers reported on the electrical properties of poly(vinyl chloride) (PVC) compositions containing PVC, a polar plasticizer, and a copolymer of 1-octadecene and maleic anhydride. (Saad, A. L. G., Hassan, A. M., Gad, E. A. M. Electrical Properties of Poly(vinyl chloride) Compositions, Journal of Applied Polymer Science, 49(10): 1725-31 (1993).) Electrically conductive polymer-filler composites comprised of a polycarbonate and an acrylonitrile-butadiene-styrene copolymer wherein the ratio of the polycarbonate and the acrylonitrile-butadiene-styrene copolymer ranged from 4 to 6 to 6 to 4 have been reported by Kim and coworkers. (Kim, W. and Lee, Y., Electrically Conductive Polymer/Filler Composites, International Patent Application No.: PCT/KR2011/010189, Publication Number WO20122012115344.)
Additionally, polymeric Langmuir-Blodgett films containing a metal binding ligand, such as imidazole, formed from polymers obtained by the reaction of histamine with poly(maleic anhydride-alt-1-octadecene) have been reported. (Jeong, H., Lee, B-J., Cho, W. J., Ha, C-S., Polymeric Langmuir-Blodgett Films Containing Imidazole-coordinated Metal Complexes, Polymer, 41(14): 5525-5529 (2000); Jung, S-B., Yoo, S-Y., Kwon, Y-S., Characterization of Metal-ion Complexes of IMI-O Polymer LB Films, J. Kor. Phys. Soc., 37(4): 378-308 (2000); Yoo, S-Y., Shin, H-K., Jeong, H., Park, J-C., Kwon, Y-S., Structure Analysis of Langmuir and Langmuir-Blodgett Films with Metal Complexes, Mol. Cryst. and Liq. Cryst., 337:357-360 (1999).) Similar films using polymers composed of other nitrogen-containing metal-binding ligands, such as 4-aminopyridine, 4-aminomethylpyridine, or polyimide, have also been reported. (Nagel, J., Ulrich, O., Langmuir-Blodgett Layers from Polymer-metal Complexes: Behavior of Monolayers and Preparation of Multilayers, Polymer, 36(2):381-386 (1995); Bruckner-Lea, C., Petelenz, D., Janata, Use of Poly(octadec-1-ene-maleic anhydride) for Interfacing Bilayer Membrane Supports in Sensor Applications, J., Microchimica Acta 100:169-185 (1990).)
Hydrophobicity and Acid Number:
In reference to polymeric materials containing carboxylic acid functional groups, acid number is defined as the number of milligrams of potassium hydroxide required to neutralize 1 gram of the polymer. Thus, it is representative of the molar ratio of carboxylic acid groups to polymer and reflects the polar acid content of the polymers or resins. The greater the acid value, the greater the number of carboxylic acid groups, and the greater the polarity of the molecule.
In reference to Poly(octadec-1-ene-maleic anhydride), Suzuki, Y in U.S. Pat. No. 5,298,568 described a modified olefin resin which can be dissolved in water by neutralization with an alkali and has an acid value of at least 30. These resins were obtained from “an α-olefin having at leas 6 carbon atoms and maleic anhydride with at least one modifier have at least one functional group selected from the class consisting of hydroxyl, amino, aziridinyl and mercapto groups”. Further, he teaches that in order to obtain the desired water solubility, the “acid value of the modified olefin resin is at least 30, preferably 80 or more. A modified resin having an acid value less than 30 hardly shows alkali solubility and water compatibility”.
Suzuki teaches that resins with low acid numbers (less than 30) are water insoluble, while those greater than 30 are water soluble. Suzuki teaches away from the polymers described in the present invention, as the polymers described in the present invention are water insoluble and hydrophobic with acid numbers greater than 100. The resins disclosed by Suzuki are also limited in the metals they are capable of binding. Suzuki discloses that his resins bind transition metal compounds having a valence of at least 2. The polymers described in the present invention are capable of binding metal compounds having a valence of at least 1. Koide, et al., in Japanese Patent Number 05-202234 describe copolymer resins composed of an α,β-ethylenically unsaturated monomer with an ethylenically unsaturated dibasic acid or its anhydride that are chelating agents. The resins described by Koide, having an acid value of 20 to 100, are hydrophobic, while those with greater acid values are hydrophilic. The polymers detailed in the present invention are water-insoluble, hydrophobic chelating agents having acid numbers greater than 100. Additionally, the agents described by Koide chelate sodium, potassium, and magnesium. The polymers disclosed in the present invention do not bind sodium, potassium, or magnesium. Thus, Koide teaches away from ethylene-based, water-insoluble, hydrophobic polymers having acid numbers greater than 100 that are able to bind metals.
Limitations of Current Conducting Polymers:
Presently, all conducting polymers suffer from one or more of the following limitations: poor processability, the lack of essential mechanical properties, and a high degree of internal resistance and limited device performance with polymers containing dopant ions. Further, all conducting polymers structurally require either conjugated multiple bond systems or fluorocarboxylic acid functional groups and ligand-stabilized transition metals. Thus, the prior art teaches away from conducting polymers, such as 1-octadecene, polymer with 2,5 furandione, metal salts, that do not contain conjugated multiple bond systems, fluorocarboxylic acid functional groups, or ligand-stabilized transition metals.
Further, the use of 1-octadecene, polymer with 2,5 furandione as a component in conducting polymers has been limited to its use solely as a backbone, or support. These observations indicate that the use of 1-octadecene, polymer with 2,5 furandione as both a backbone or support and the metal binding functional group was not anticipated or obvious to those schooled in the art.
In summary, the characteristics of the polymer described herein are not predicted in the literature, as conductivity is obtained without the requirements for either a conjugated multiple bond system or flurorcarboxylic acid functional groups and ligand-stabilized transition metals. As such, the use of the polymer as a conductor in the manner described is unexpected, constitutes a new and unexpected use for the polymer, and functions in a new, unanticipated manner.
While these compounds disclosed in the prior art fulfill their respective, particular objectives and requirements, the aforementioned patents and prior art do not describe the Conducting Polymers, 1-Octadecene, Polymer with 2,5 Furandione, Metal Salts that allow the use of conducting polymers without the need for conjugated multiple bond systems or fluorocarboxylic acid functional groups, ligand-stabilized transition metals, or metal binding homopolymer components.
In this respect, the Conducting Polymers, 1-Octadecene, Polymer with 2,5 Furandione, Metal Salts, according to the present invention substantially depart from the conventional concepts and compounds described in the prior art, and in doing so provide unique conductive polymer compounds capable of electron transmission, with the polymer compounds also being capable of preventing fouling on a surface.
Therefore, it can be appreciated that there exists a continuing need for new and improved Conducting Polymers, and 1-Octadecene, Polymer with 2,5 Furandione, Metal Salts, which can be used for preventing the spread of infective agents. In this regard, the present invention substantially fulfills this need.
1-Octadecene, Polymer With 2,5 Furandione, Metal Salts, prepared from 1-Octadecene, Polymer with 2,5 Furandione, Sodium Salt, as previously described (Laurino, J. P., U.S. Pat. No. 7,964,688) or by other preparative means as would be evident to those skilled in the art, possess novel conductive polymer characteristics. The characteristics include, but are not limited to, conductivities of 4 S/cm to 200 S/cm or more, depending upon the concentration and nature of the metal bound, conductivities proportional to the amount of metal bound to the polymer, the ability to bind metals having a +1, +2, +3, +4, or +5 valence charge to the polymer, and the ability to bind two or more different metals to separate binding sites on the polymer.
Essential Characteristics of the Polymers:
The polymers, as herein described, contain numerous carboxylate groups directly bound to the polymer backbone that provide the hydrophilic metal-binding characteristics. The polymers also contain a water insoluble hydrophobic aliphatic polymer backbone. These polymers provide specific, selective, and fast complexation of metal ions, thereby producing conductive polymer materials.
Comparison of Conductivities:
The conductivities of various conductive polymers are given in the table below:
The conductivity readings of the 1-Octadecene, Polymer With 2,5 Furandione, Metal Salts were obtained using the lowest concentration of metal salt solution for the conducting polymer preparation. Increasing conductivities were obtained when metal salt solutions of increasing concentrations were used for the preparation of the conducting 1-octadecene, polymer with 2,5 furandione, metal salts.
The polymers, herein described, have several potential uses that are beneficial. The polymers can be used as a conducting means of electrical energy. The term “conducting means” which is at least one structures from the group of structures, which are used for the conduction of electricity, which includes films, wires, electrodes, nanowires, fibers, filaments, inks, printed circuits, and printed products.
The polymer can also be used as an “electronic component means,” which is at least one member of the group of electronic components which includes electrolytic capacitors, switches, injection molded products, temperature gauges, solenoids, photovoltaic cells, displays, electric glues, energy storage cells including batteries, semiconductors, biosensors, and devices which are used to measure electrical impedance. When used in energy storage cells, it is understood that at least one cell of the energy storage cell utilizes the polymer herein described. The energy storage cells are comprised of at least two electrodes associated with at least one cell.
Additionally, since the role of transition metal ions as disinfectants of bacteria and viruses has been previously reported (McDevitt, C. A., Ogunniyi, A. D., Valkov, E., Lawrence, M. C., Kobe, B., McEwan, A. G., Paton, J. C., A Molecular Mechanism for Bacterial Susceptibility to Zinc, PLoS Pathog. 7(11) 2011; Thurman, R. B., Gerba, C. P., Bitton, G., The Molecular Mechanisms of Copper and Silver Ion Disinfection of Bacteria and Viruses, Crit. Rev. in Environ. Control. 18(4):295-315 (1989); Molteni, C., Abicht, H. K., Solioz, M., Killing of Bacteria by Copper Surfaces Involves Dissolved Copper, Appl. Environ. Microbiol., 76(12): 4099-4101 (2010)), these unique metal-bonded polymers can serve as components of antimicrobial and antiviral “barrier means”, which is at least one of a group of barrier means which includes bandages, gowns, gloves, sutures, surgical draping, clothing, bedding, and barrier items including sheets, screens, bags, masks, head covers, air filters, room dividers, flooring, and injection molded plastics.
Lead has long been recognized as a highly effective material in providing a protection barrier from various sources of radiation (A Guide to the Use of Lead for Radiation Shielding, A publication of the Lead Industries Association, Inc., 292 Madison Avenue, New York, N.Y.). As such, these unique lead-bonded and other metal-bonded polymers can serve as components of “radiation barrier means”, which is at least one of the group of radiation barriers which includes clothing, gloves, screens, room partitions, draping, sheets, bedding, gowns, bags, masks, head covers, air filters, room dividers, flooring, and injection molded plastics.
Similarly, these polymers can also be used as an “anti-fouling means”, which is at least one of the group of anti-fouling agents which includes anti-mold agents, anti-mildew agents, anti-algal agents, and anti-fouling agents. (Kheybari, S., Samadi, N., Hosseini, S. V., Fazeli, A., Fazeli, M. R., Synthesis and Antimicrobial Effects of Silver Nanoparticles Produced by Chemical Reduction Method, Daru, 18(3): 168-172 (2010); Schiff, K., Diehl, D., Valkirs, A., Copper Emissions from Antifouling Paint on Recreational Vehicles, Marine Pollution Bulletin, 48(3-4):371-377 (2004)).
These polymers can be used in the preparation of “photographic means”, which is at least one of the group of photographic materials which includes photosensitive materials containing polymer chelated metals, such as silver, platinum, palladium, and gold. (Arentz, D., Photography in Platinum and Palladium, Platinum Metals Review, 49(4): 190-195 (2005); Sun, Y., Xia, Y., Shape-Controlled Synthesis of Gold and Solver Nanoparticles, Science, 298, 2176 (2002)).
These polymers can also be used in the preparation of “treatment means”, which is at least one of the group of treatments which includes anti-cancer treatments, anti-inflammatory treatments, anti-infective treatments, anti-diabetic pharmaceutical compounds and cosmetic preparations, and also as an anti-infective means. They can also be used in the preparation of dietary supplements, diagnostic agents, and dental filings and implants. (Warra, A. A., Transition Metal Complexes and Their Application in Drugs and Cosmetics—A Review, J. Chem. Pharm. Res., 3(4): 951-958 (2011)) The herein described water-insoluble polycarboxylate polymer may also be used as a vehicle for carrying anti-infective agents, or as an anti-infective agent itself.
These polymers can also be used in the preparation of chelated fertilizers and inorganic pesticides, or “fertilizer means” and “pesticide means”, respectively. A fertilizer means is at least one of the group of fertilizer micronutrients which includes iron, manganese, zinc, copper, and nickel. Chelated fertilizers have been developed to increase the utilization efficiency of micronutrients, such as iron, manganese, zinc, copper, and nickel. Since these micronutrients are easily oxidized or precipitated in soil, the utilization of the unchelated metal is not very efficient (Liu, G., Hanlon, E., Li, Y. Understanding and Applying Chelated Fertilizers Effectively Based on Soil pH, Document HS 1208, University of Florida, Horticultural Sciences Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, November 2012; Sekhon, B. S., Chelates for Micronutrient Nutrition among Crops. Resonance, 8(7): 46-53 (2003)).
Copper, cadmium, cobalt, nickel, lead, zinc, iron, manganese, and other metals are also components of common pesticides. (Gimeno-Garcia, E, Andreu, V., Boluda, R., Heavy Metals Incidence in the Application of Inorganic Fertilizers and Pesticides to Rice Farming Soils, Environmental Pollution, 92(1): 19-25 (1996)). A pesticide means is at least one of the group of pesticide components which includes copper, cadmium, cobalt, nickel, lead, zinc, iron, and manganese.
These polymers can also be used as a “catalyst means”. Numerous investigators have reported on the use of platinum-polyacid, palladium polyacid, rhodium metal-polymer, and other transition metal-polymer catalysts.
When used herein the term “catalyst means” is at least one of the group of polymer catalysts that includes a transition metal (Mayer, A. B. R., Mark, J. E., and Hausner, S. N. Collodial platinum-polyacid nanocatalyst systems), or a non transition metal. The non-transition Metals being Aluminum and Lead. The transition Metals being Scandium, Titanium, Vanadium, Chromium, Manganese, Iron, Cobalt, Nickel, Copper, Zinc, Yttrium, Zirconium, Niobium, Molybdenum, Technetium, Ruthenium, Rhodium, Palladium, Silver, Cadmium, Hafnium, Tantalum, Tungsten, Osmium, Iridium, Platinum, Gold, Mercury, Lutentium, and Rhenium.

Sci., 70(6):1209-1219 (1998); Banavali, R., Deetz, M. J., and Schultz, A. K. Transition Metal Catalysts, in The Power of Functional Resins in Organic Synthesis (eds. J. Tulla-Puche and F. Albericio), Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim, Germany (2009).)

10 grams of the polycarboxylate is added to a solution of the metal nitrate at room temperature. The reaction mixture is allowed to react for 5 minutes, vacuum filtered, and the solid conducting polymer dried.
There are other methods to produce the conducing polymers, 1-Octadecene, Polymer with 2,5-Furandione, Metal Salts. One method is to use the corresponding polyester. Subsequent hydrolysis of the polyester would produce the polycarboxylate, which could then be reacted with the metal nitrate solution. Additionally, other soluble metal salts can be used to prepare the conducting polymer from the polycarboxylate. These reaction schemes would be obvious to someone skilled in the art of organic synthesis or polymer synthesis.
It should also be noted that the polycarboxylate has two different binding site populations. In
