电致变色材料的变色机理及其研究进展

Color-changing Mechanism of Electrochromic Materials and Their Research Progress

电致变色材料是目前公认的最有发展前途的智能材料之一。简要介绍了无机电致变色材料(如WO3、MoO3、NiO、IrOx等)和有机电致变色材料(如紫罗精、稀土酞花菁、聚苯胺等)这两种不同类型的变色材料及其研究现状,阐述了电致变色现象及其变色机理,并展望了其应用前景和发展方向。

Electrochromic material is one kind of acknowledged prospective intelligence materials at present. In this article, inorganic electrochromic materials such as WO3, MoO3, NiO, IrOx and organic elctrochromic materials such as viologen, rare earth phthaloeyanin, polyaniline and their current situation are briefly introduced. At the same time, their color-changing mechanisms are explained, and their application foreground and developing direction are presented.
