摘要
研究了光聚合物材料聚甲基丙烯酸肉桂酰氧基乙酯 (CEMC)对液晶材料LC 6 710A的取向作用 ,取向层表面在光化学反应前后的变化 ;测量了光控取向膜液晶盒中液晶分子的预倾角及单面光控取向扭曲向列液晶显示器(TNLCD)的电光特性和时间响应特性 ,研究了这种材料的光化学反应过程 ,以及液晶分子排列取向的机理 .
We have investigated the alignment of liquid crystal LC\|6710A molecules with Cinnamate material 2\|(cinnamoyloxy) ethyl methacrylate (CEMC).The change of alignment of substrate surface was observed before and after photochemical reaction.The pretilt angle of LC molecules in photo\|alignment cell was measured.The electro\|optical property and time response curves of twisted nematic liquid crystal display (TNLCD) with single side photo\|alignment substrate were obtained.The process of photochemical reaction of the material CEMC using linear polarized photopolymerization method by UV\|light was studied in this paper.The mechanism of liquid crystal molecules alignment on substrate surface was discussed.
