SYNTHESIS OF POLY(BENZYLMETHACRYLATE-CO-PERFLUOROOCTYLETHYLMETHACRYLATE) AND ELECTROOPTICAL PROPERTIES OF THE RESULTANT POLYMER LIQUID CRYSTAL COMPOSITE FILMS

摘要

Methacrylate copolymers of benzylmethacylate (BMA) and perfluorooctylethylmethacrylate (FMA) were synthesized and applied to the polymer/liquid crystal (LC) composite films. The copolymers were prepared by a radical solution polymerization. The high composition of FMA resulted in a precipitation during the polymerization. The contact angle of the LC on the copolymer films decreased with increasing FMA composition. Due to a small interaction between the LC and the copolymers, the copolymer/LC composite films showed low driving voltage in the range of 18-25 V-max corresponding to about 1/3 the value of the poly(methyl methacrylate) (PMMA)/LC composite film.
