摘要

研究了聚合电场波形对常黑模式聚合物稳定胆甾相液晶（PSCT）网络形貌和光电性能的影响。采用紫外光聚合诱导相分离法（PIPS）制备聚合物稳定胆甾相液晶，通过使用3种不同的聚合电场波形（方波、正弦波和三角波）来控制聚合物网络的形貌，改善PSCT的光电性能。聚合电场为方波时，聚合物网络最为疏松，阈值饱和电压最小，响应时间最长，迟滞宽度最大；而聚合电场为三角波时，聚合物网络最为致密，阈值饱和电压最大，响应时间最短，迟滞宽度最小。

Abstract

The effect of curing electric field waveform on the morphology of polymer network and the electro-optic properties of polymer-stabilized cholesteric texture (PSCT) was investigated. PSCT was prepared by means of polymerization induced phase separation (PIPS). By using three kinds of curing electric field waveform

the network morphology of PSCT can be controlled and the electro-optic properties of PSCT can be improved. When the curing electric field waveform is square

the polymer network is loosest

which results in the lowest threshold (saturation) voltage

longest response time

and largest hysteresis width. And the tightest polymer network can be observed with the triangle curing electric field waveform

which leads to the highest threshold (saturation) voltage

the shortest response time

and the smallest hysteresis width.
