一种红色电致变色材料及其制备方法与组件
摘要：
本发明涉及一种红色噻吩类聚合物电致变色材料，所述材料为[3,4-二(2-乙己氧基)噻吩]-噻吩-[3,4-二甲氧基噻吩]共聚物，GPC(THF vs PS standards):Mw ca.1.17*105g/mol,Mn ca.4.34*104g/mol,分子量分布系数PDI=2.71;δH(400MHz，CDCl3):7.00(br,1H),3.90(br,5H),3.00-0.50(br,35H)。所述聚合物薄膜颜色可以在红色和透明之间转变，循环寿命大于10000次，具有驱动电压低，氧化态透明且透过率高、响应时间短、可喷涂操作等特点，可用于电致变色窗、电致变色显示器等器件，具有广阔的应用前景。
摘要（英）：

The invention relates to a red thiophene type polymer electrochromic material. The material is a [3,4-di(2-ethyloxy)thiophene]-thiophene-[3,4-dimethoxy thiophene] copolymer, GPC (THF vs PS standards):Mw ca.1.17*10<5>g/mol, Mn ca.4.34*10<4>g/mol, and the molecular weight distribution coefficient PDI is 2.71; and delta H (400MHz,CDCl3):7.00(br,1H), 3.90(br,5H), 3.00-0.50(br,35H). The color of a thin polymer film can be changed between red and transparency, the cycle life is more than 10000 times, the material has the characteristics that the driving voltage is low, the oxidation state is transparent, the transmittance is high, the response time is short, spraying operation can be realized and the like, and the material can be used for devices such as electrochromic windows, electrochromic displayers and the like and has broad application prospects.
