摘　　要：液晶材料作为信息化时代的基础材料已经在显示领域实现了广泛的商业化应用。液晶/高分子复合材料既具有液晶材料的各向异性及外场响应特性,还具有高分子易加工成本低等特点,可以加工成大面积柔性调光薄膜,因而在建筑玻璃、智能车窗中具有广阔的应用前景。此外,液晶与高分子材料之间的相互作用会对液晶小分子取向产生影响,液晶小分子也可以作为模板控制高分子网络的形成的方向,使复合材料薄膜实现一些新的功能和特性,因此激发了大量国内外学者的研究兴趣。本文将详细介绍液晶/高分子复合材料的类型、特点、在调光膜中的应用及反式电控调光膜的最新研究进展。在此框架下,将重点阐述基于液晶/高分子复合材料的反式电控调光膜的一些新的制备方法,同时介绍目前存在的挑战及需要解决的问题,最后对反式电控调光膜近期可能实现的应用进行了展望。Liquid crystals as the basic materials in modern era of information age have been wildly commercially used in displays.Liquid crystal/polymer composites not only have the advantages of anisotropy and stimulus responsive characteristics similar with liquid crystals,but also have the processibility and cost-effectiveness similar with polymers,which have promising applications in building glass and smart car windows.Besides,the interactions between liquid crystals and polymers will affect the molecular alignment of liquid crystals,meanwhile liquid crystals could also affect the formation direction of polymer networks.Thus a lot of interest has been motivated in the study of liquid crystal/polymer composites.Different types of liquid crystal/polymer composites,their characteristics,applications in light-transmittance controllable films and recent advances in reverse-mode films are reviewed.In the framework,we will make emphasis on the summary of the progress in preparation of reverse-mode light-transmittance controllable films based on liquid crystal/polymer composites.Simultaneously,the challenges and applications of reverse-mode film are also discussed and prospected.
