摘要
液晶光控取向材料是近年来国际上的一个研究热点,其在液晶显示及防伪等领域有着广阔的应用前景。光控取向材料根据光反应机理的不同可分为光异构类、光降解类和光交联类材料,本文介绍了这3种类型光控取向材料的反应机理、分类特点、研究状况,并分析了存在的问题及应用前景。
LC light control materials has attracted much attention and interest because of its great applications in liquid crystal display, anti-counterfeiting techniques and so forth. According to the different photoreaction mechanism, photo-aligned material is categorized as photo-isomerization, photo-degradation and photo-crosslinking materials. Characteristics and development of study of LC light control materials are introduced and their existed problems and future applications are also analyzed.
