中文摘要：

采用紫外光聚合诱导相分离法制备聚合物稳定胆甾相液晶（PSCT），研究了单体4,4′-二［6-（丙烯酰氧基）己氧基］联苯（BAB6）、2-甲基-1，4-二［4-（3-丙烯酰氧基己氧基）苯甲酸基］对苯二酚（HCM-009）、2-甲基-1，4-二［4-（3-丙烯酰氧基丙氧基）苯甲酸基］对苯二酚（LCM）对常黑和常白模式PSCT光电性能的影响。结果表明：BAB6不具备液晶性，与液晶的相容性差，形成的聚合物网络疏松，网孔较大；HCM-009和LCM均具有液晶性，能很好地溶于液晶中。BAB6、HCM-009、LCM 3种单体形成的聚合物网络对液晶分子的锚定作用依次增强，常黑模式PSCT的阈值（饱和）电压减小，下降时间变长，迟滞宽度变大；而常白模式PSCT的驱动电压增大，响应速率变快。

英文摘要：

Polymer-stabilized cholesteric texture （PSCT） films were prepared by means of polymerization induced phase separation. The influence of different monomers, including 4,4′-bis[6-（acryloyloxy）-hexyloxy]biphenyl（BAB6）, 1,4-di-[4-（3-acryloyloxyhexyloxy） benzoyloxy]-2-methyl benzene （HCM-009） and 1,4-di-[4-（3-acryloyloxypropoxy） benzoyloxy]-2-methyl benzene （LCM）, on the electro-optic property of normal-mode and reverse-mode PSCT films was investigated. It was indicated that the monomer of BAB6 has poor solubility in liqiud crystals due to the absence of liquid crystal phase. The polymer network formed by BAB6 is loose and the averaged void size is large. While for the monomers of HCM-009 and LCM, liquid crystal phases were observed resulting in good solubility. As anchoring effect of polymer networks formed by BAB6, HCM-009 and LCM increased grandually, smaller threshold （saturated） voltage, longer decay time and larger hysteresis width were observed for normal-mode PSCT. Whereas for reverse-mode PSCT, higher driving voltage and faster response time were found.
