摘　　要：全息高分子纳米复合材料(holographic polymer nanocomposites, HPNC)是基于相干激光聚合诱导相分离原理制备的具有周期性有序结构的高分子纳米复合材料,属于多维度、跨尺度的新概念信息材料.不仅通过微米/亚微米尺度的周期性有序相分离结构存储光波的振幅、相位等全部信息,还通过引入的纳米粒子、液晶、发光分子等存储其他信息,具有信息存储容量大、光调制能力强的特点.在高端防伪、裸眼三维显示、增强现实、高密度数据存储、全息传感等高新技术领域具有重要应用价值.本文重点概述HPNC的高性能化与多功能化研究进展,并展望了HPNC的发展方向.Holography is a revolutionary technique to reconstruct the whole information of light including amplitude and phase, which has displayed transformative impacts on a myriad of fields such as display, data storage, anti-counterfeiting and stereo-advertising. For these applications, holographic polymer materials have been widely applied due to the lightweight, easy-processing and cost-effective characteristics. However, due to the small box of material pool and limited protocols to tune the properties, it is difficult for traditional holographic polymer materials to meet the increasing requirements of emerging optical and electro-optical applications.Holographic polymer nanocomposites(HPNC), which are novel polymer nanocomposites with periodically ordered structures, show transformative potential compared with traditional holographic polymer materials. They can be fabricated through photopolymerizationinduced phase separation upon laser interference patterns, during which the whole information of light is stored in the micron/submicron gratings. More excitingly, as conceptual information materials, HPNC can record added information using the incorporated functional components including nanoparticles, liquid crystals, and photoluminescent molecules. Thus, they show great application potential in high-tech fields such as advanced anti-counterfeiting, three-dimensional display to the naked eye, augmented reality and high-density data storage.Functions and performances of HPNC are not only determined by the phase separation structure, but also highly dependent on the spatial location of functional components. This minireview intends to summarize the methods for boosting the phase separation and performance of HPNC, and to introduce several useful protocols for endowing added functions to HPNC.(1) “Photoinitibitors”, which are conceptual and distinct from traditional photoinitiators or inhibitors, are of vital significance for boosting the phase separation and diffraction efficiency of HPNC gratings by the unique syn
