有机硅改性聚甲基丙烯酸甲酯—聚苯胺复合材料的制备及其电致变色性能研究

PREPARATION AND ELECTROCHROMIC BEHAVIOR OF POLY (MMA-MSMA) /POLYANILINE COMPOSITE

本文采用溶液聚合法及乳液聚合法合成了可溶性聚苯胺 ,用光电子能谱、X -射线衍射对其本征态及掺杂态的结构进行了表征。以甲基丙烯酸甲酯 -甲基丙烯酰丙基三甲氧基硅烷共聚物为基体 ,用溶液复合法制备了聚苯胺复合电致变色膜 ,并采用扫描电镜、循环伏安法等对其结构和电致变色性能进行研究。结果表明复合电致变色膜在稳定态时仅出现第二氧化峰 ,在外加电压作用下其颜色在绿色至蓝黑色之间可逆变化。

In this article dissoluble PAn by ways of liquor and latex and electrochromic composite film by compounding doped PAn with P(MMA-MSMA)in solution were prepared.The structures and electrochromic behaviors of the films were analyzed by XPS spectrum,X-radial diffraction,scanning electron microscope,cyclic voltammetry,etc.The results show that the electrochromic composite films have just undergone a second oxidation stage after the eighth cycles in cyclic voltammetry and can reversibly change their color from green to dark blue.
