Abstract
Liquid crystal/polymer composite (LCPC) films were prepared by electron beam polymerization of nematic liquid crystal and two-functional monomer (EB-LCPC) and by emulsification of nematic liquid crystal using polyvinylalcohol (PVA-LCPC). A factor related to hysteresis of these film was investigated by analyzing the dependence of transmittance and capacitance on applied voltage. EB-LCPC was smaller in the hysteresis and the applied voltage dependence of hysteresis than PVA-LCPC. It was assumed that hysteresis occurs by structure change of LCPC film due to molecular motion of its polymer matrix.
