选用1,4-双[4-(6-丙烯酰氧基己氧基)苯甲酰氧基]-2-甲苯(C6M)/(S)-4'-(2-甲基丁基)-4-联苯腈(CB15)/安息香二甲醚(IRG651)/SLC1717复合体系,通过紫外光聚合诱导相分离法制备了反式聚合物稳定胆甾相织构(R-PSCT)膜.研究了聚合温度和紫外光辐照度对所制备的R-PSCT膜电光性能的影响.随着聚合温度的升高或紫外光辐照度的减小,R-PSCT膜的驱动电压、对比度和开态响应时间减小,而关态响应时间增大.在聚合温度为293 K和紫外光辐照度为0.75 mW·cm-2时,所制备的R-PSCT膜具有较佳的电光性能.

ABSTRACT Reverse-mode polymer-stabilized cholesteric texture ( R-PSCT) films were prepared from ultraviolet polymerization-in-duced phase separation in a mixture of 1,4-di[4-(6-acryloyloxyhexyloxy) benzoyloxy]-2-methylbenzene(C6M)/ (S)-4’-(2-methyl-butyl)biphenyl-4-carbonitrile(CB15)/2,2-dimethopxy-1,2-diphenyl-ethanone(IRG651)/SLC1717. The effects of curing temperature and ultraviolet ( UV) irradiance on the electro-optical properties of R-PSCT films were studied. When the curing temperature increases or the ultraviolet irradiance decreases, the driving voltage, the contrast ratio and the on-state response time decrease, but the off-state response time increases. The R-PSCT film prepared at a curing temperature of 293 K and an ultraviolet irradiance of 0.75 mW·cm-2 has better electro-optical properties.
