Abstract
Film morphology and electrooptic performance of poly (styrene-co-ethyl methacrylate) (PSEMA)/E7 composite films have been studied for various copolymer compositions. The effects of copolymer composition on the o ptical response of the films were measured as function of voltage and frequency of applied AC electric field. It was found that the LC domai n size increased significantly with styrene content of PSEMA up to 32. 5%, beyond which a decrease was noted. The electrooptic responses were mainly governed by the film morphology.
