Effects of Mesogenic Compound with High Birefringence on Electro-Optical Properties of Heat-Cured Polymer-Dispersed Liquid Crystal Films

Addition of mesogenic compound with high birefringence in nematic liquid crystal resulted change in the electro-optical properties of polymer-dispersed liquid crystal (PDLC) films considerably. The PDLC films were prepared from thermally polymerization-induced phase separation in heat curable monomers/nematic liquid crystal mixtures, and the effect of mesogenic compound with high birefringence on the electro-optical properties of PDLC films was studied. Therefore, when the mesogenic compound was doped in different concentrations, their quality fraction played considerable role in deciding the electro-optical parameters of the PDLC films.
