摘要

为了调节聚合物网络与液晶分子之间的相互作用，从而改善聚合物稳定胆甾相液晶（PSCLC）的光电性能，本文采用紫外光聚合诱导相分离法（PIPS）制备了聚合物稳定胆甾相液晶，通过控制2种单体RM257与BAB6的比例来改善器件性能。随着RM257含量的减少，聚合物网络由取向排列的纤维状结构向疏松不规整的交联状结构转变，形成的聚合物网络对液晶分子的锚定作用减弱，聚合物稳定胆甾相液晶的饱和电压降低，关闭时间增大。当RM257与BAB6质量比为1：4时，聚合物稳定胆甾相液晶器件具有较好的对比度。

Abstract

The interaction force between polymer network and liquid crystal molecules was adjusted by controlling two monomer ratio

the photoelectric performance of the PSCLC was also improved by the method. Polymer stabilized cholesteric liquid crystal was prepared by the method of UV polymerization induced phase separation (PIPS). As the concentration of RM257 decreased

the saturated voltage reduced and the field-off response times of PSCLC increased with the polymer network changing from fiber-like to crosslink-like. When the proportion of RM257 and BAB6 is 1:4

the contrast reach maximum.
