基于国内外最新研究文献 ,系统论述了新型功能性侧链液晶聚丙烯酸酯的液晶性质、光电性质及应用前景。指出这类聚合物一般显示热致性向列型或近晶型液晶相 ,液晶相转变温度和液晶态温度范围随链结构的不同发生显著变化 ,具有较短的电场及光场响应时间 ,对某些有机物质具有选择吸附能力。可望用作光学信息储存材料、气相色谱固定相材料以及复合材料的界面改性材料等。
Based on the latest research literature at home and abroad, the liquid crystal properties, photoelectric properties and application prospects of the new functional side-chain liquid crystal polyacrylate are systematically discussed. It is pointed out that these polymers generally show thermotropic nematic or smectic liquid crystal phases. The liquid crystal phase transition temperature and the liquid crystal temperature range vary significantly with the chain structure, and have short electric field and light field response time. Some organic substances have selective adsorption capacity. Expected to be used as optical information storage materials, gas phase stationary phase materials and composite materials such as interfacial modification.
