热致调光聚合物材料进展

Recent Advances in Thermally Light-adjusting Polymeric Materials

热致调光聚合物材料能随环境温度变化发生可逆的透明度或颜色转变,从而广泛应用于智能窗、温度传感器及热可逆记录等热光学领域。现有的各种热致调光聚合物材料主要分为热致散射、热致变色以及双功能3类。详细介绍了近年来这3类热致调光聚合物材料的研究状况,分析了其调光机理及性能,并展望了其未来的发展。

Thermally light-adjusting polymeric materials that can adjust their transparency or color reversibly with changing environment temperatures, have been widely used in intelligent windows, thermo-sensors, thermo-reversible recording media and other thermo-optical applications. The reported thermally light-adjusting polymeric materials are mainly classified into three types, such as thermotropics, thermochromics and hybrids. A current overview of the research progress in these materials is given in this paper. The relevant mechanisms and properties are analyzed, and then future prospects of these materials are discussed.
