Research progress of smart windows based on polymer stabilized liquid crystals

聚合物稳定液晶(Polymer Stabilized Liquid Crystals,PSLCs)是一种含少量聚合物网络的液晶-聚合物复合材料,凭借良好的光学性能及外场响应性,PSLCs可被用作电子纸、调光膜、传感器等器件。近年来,随着能源供应的紧张以及保护环境的实际需求,调光膜的重要性逐渐被凸显。PSLCs调光膜作为其中的一个重要分支,根据响应方式的不同其又可分为多种类型。为了进一步改善PSLCs调光膜的光学性能,丰富其外场调控性,研究者从纳米粒子掺杂、染料掺杂以及聚合物网络结构改进等方面入手开展了许多研究。本文主要对近些年基于聚合物稳定液晶材料的智能调光膜领域研究进展进行了系统总结,并对未来PSLCs调光膜的发展趋势做出了展望。

Polymer stabilized liquid crystals(PSLCs)are a class of liquid crystal/polymer composite materials containing a small amount of polymer network.Due to their good optical properties and field responsive characteristics,they can be used as electronic paper,smart windows,sensors and other devices.In recent years,with the pressure of energy supply and the actual need of environment protecting,the importance of smart windows has gradually been highlighted.As the important of the branches,there is a variety of classification of PSLCs-based smart windows depending on the different response mode.In order to further improve their optical properties and enrich its field regulation styles,many researches have been carried out recently from the aspects of nano-particle doping,dye doping and polymer network structure improvement,etc.In this paper,the research progress of PSLCs-based smart windows in the past few years is reviewed and discussed,and the future development trend of PSLCs-based smart windows is forecasted.
