Abstract
The present provides a method of fabricating a polymer dispersed liquid crystal (PDLC) thin film. The method of fabricating the PDLC of the present application forms the first solution by mixing the liquid crystal and the graphene nanoparticles; prepares the prepolymer by using the citric acid and the 1,8-octanediol, or the citric acid, the 1,8-octanediol and the 1,8-octanediol; forms the second solution by dissolving the prepolymer in the anhydrous ethanol; then obtains the mixture prepolymer of the polymer dispersed liquid crystal and the graphene nanoparticles by mixing and uniformly stirring the first solution and the second solution; and obtains the PDLC thin film after the mixture prepolymer is polymerized for several days.
