Claims
- 1. A method of making a film of an encapsulated liquid crystal structure comprising a liquid crystal composition dispersed in a containment medium, which method comprises the steps of
- (a) adding a reactive additive means to the liquid crystal composition, the reactive additive means being selected from the group consisting of acrylic compounds, methacrylic compounds, epoxy compounds, aldehydes, and thiol compounds;
- (b) forming an emulsion of the liquid crystal composition, including the reactive additive means, dispersed in the containment medium;
- (c) coating the emulsion onto a support sheet and drying the emulsion to form a film of encapsulated liquid crystal structure supported by the support sheet; and
- (d) initiating the reaction of the reactive additive means to deposit the reactive additive means on the surfaces of the containment medium in contact with the liquid crystal composition.
- 2. A method according to claim 1, wherein the reactive additive means is an acrylic or methacrylic compound.
- 3. A method according to claim 1, wherein the reactive additive means is an acrylic compound or a methacrylic compound which is a silane coupling agent having acrylic or methacrylic functionality.
- 4. A method according to claim 1, wherein the reactive additive means is an epoxy compound.
- 5. A method according to claim 1, wherein the reaction of the reactive additive means is initiated by irradiation with ultraviolet light.
- 6. A method according to claim 1, wherein the reaction of the reactive additive means is initiated by heating.
