ABSTRACT:
A novel PDLC film composition that contains a mixture of acrylate monomers that provide certain advantages when combined with a liquid crystal. The mixture of acrylate monomers contains one monofunctional monomer that gives rise to a homeotropic anchoring condition, and one monofunctional monomer that gives rise to homogeneous anchoring condition in the PDLC film made from the composition of the present invention at a selected temperature. The monomer mixture also contains a polyfunctional acrylate monomer. PDLC films made from these compositions have advantages over films made from compositions that have only one monofunctional acrylate monomer. Also, by using the process of the present invention, one can prepare a PDLC film that exhibits a low switching voltage in a desired temperature range.
