中文摘要：
以紫外光聚合的聚氨酯丙烯酸酯（PUA）为基体，通过紫外光聚合诱导相分离法制备了不同液晶含量、不同引发剂含量的聚合物分散液晶（PDLC）薄膜。使用改装的紫外分光光度计和超景深显微镜研究了不同液晶含量、不同引发剂含量对PDLC薄膜的电光性能和微观形貌的影响。研究表明，随着液晶含量的增加，PUA基的PDLC的液晶微滴尺寸变大，电光性能变好；随着引发剂含量的增加，PUA基的PDLC液晶微滴变小，Ton增加。
英文摘要：
The reactive PUA was used as the matrices to prepare PDLC films with various liq- uid crystal contents and different concentrations of initiator by UV polymerization induced phase separation. The influence of concentrations of initiator and liquid crystal contents on the morphology and electro-optical property of PDLC films was studied through modified ultraviolet spectroscopy and digital microscope. It indicated that with the increase of the liq- uid crystal contents, the diameter of the liquid crystal droplets increased and the electro-opti- cal property of PDLC films get better obviously and with the increase of the concentrations of initiator, the size of the liquid crystal droplets became smaller and Ton increased.
