摘要 全息高分子/液晶复合材料是一类具有全息功能的结构有序复合材料,通过富高分子相与富液晶相的周期性排列,存储相干光的振幅、相位等全部信息。依据液晶含量和制备方法,全息高分子/液晶复合材料主要分为全息聚合物分散液晶(HPDLC)、全息聚合物稳定液晶(HPSLC)、聚合物-液晶-聚合物层状物(POLICRYPS)。主要综述了近5年HPDLC的结构及性能调控方法,概述了HPSLC和POLICRYPS的发展动态,总结了它们在高端防伪、增强现实等高新技术领域的应用,并对未来发展方向进行了展望。 Holographic polymer/liquid crystal(LC)composites are one type of structure ordered composites with the holographic function,which represent the unique capability of reconstructing the whole infomation of coherent lasers by using the periodically arranged polymer-rich and LC-rich phases.According to LC contents and preparation methods,holographic polymer/LC composites comprised holographic polymer dispersed liquid crystal(HPDLC),holographic polymer stabilized liquid crystal(HPSLC),and polymer-liquid-crystal-polymer slices(POLICRYPS).This review mainly summarizes the methods to tune the structure and performance of HPDLC in recent 5 years,along with the research progress of HPSLC and POLICRYPS.Applications of holographic polymer/LC composites in high-tech fields such as advanced anti-counterfeiting and augmented reality are also highlighted.Last,research challenges and opportunities are proposed.
