摘　　要：许多无机和有机材料表现出氧化还原状态(还原/氧化形式),且具有明显差异性的紫外-可见(电子)吸收带。通过对材料薄膜施加电压,使其发生氧化和还原状态间的转换,从而导致颜色的改变,即为电致变色。主要从电致变色材料的发展历程、变色机理、分类及应用等方面进行了简单概述,最后对电致变色材料的未来发展进行了展望。Many inorganic and organic materials exhibit REDOX states(reduced/oxidized forms)with significantly different UV-visible(electron)absorption bands.By applying a voltage to the material film,the transition between oxidation and reduction states occurs,resulting in a change in color,which is called electrochromism.In this paper,the development history,mechanism,classification and application of electrochromic materials are briefly summarized.Finally,the future development of electrochromic materials is prospected.
