全固态电致变色器件用聚合物电解质研究进展

Research progress of polymer electrolyte used in all solid-state electrochromic device

固体电解质是构成全固态电致变色器件(ECD)的关键材料之一,其在器件中作为电解质和电极间隔膜,为电致变色反应提供所需要的补偿离子。主要概述了ECD的结构及其对聚合物电解质的要求,重点介绍固体聚合物电解质的类别和改性方法,综述其在ECD方面应用的最新研究及发展方向。

Polymer electrolyte is a fundamental part in an all solid-state electrochromic device （ECD）. It works as electrolyte and inter-electrode diaphragm, and provides ions for electrochromism occurrence. The paper introduces the structure of a typical ECD and its requirements for polymer electrolyte. The classification and modificating ways of some solid polymer electrolyte are presented, and their application progress in ECDs is reviewed.
