| 摘 要： | 以室温离子液体1-丁基-3-甲基咪唑六氟磷酸盐[BMIM]PF6为溶剂及支持电解质，通过电化学方法制备聚(3-己基噻吩)(PHexT)膜。采用循环伏安法和扫描电子显微镜，对膜的电化学性质及形貌结构进行表征。同时通过紫外可见光谱、计时电流、计时库仑以及计时吸收曲线等方法研究聚合物膜的光谱电化学和电致变色特性，并在此基础上制备PHexT膜的电致变色器件。实验结果表明，在离子液体中制备的PHexT膜光滑致密，掺杂态时为蓝色，脱掺杂时为桔红色，并且具有高的颜色对比度 (40%)，较短的响应时间 (2.5 s) 和高的电致变色着色效率 (230cm2/C)，该膜制成的固态电致变色器件具有很好的电致变色性能和长的循环寿命。

| Abstract: | Electrochemical polymerization in a room temperature ionic liquid, 1‐butyl‐3‐methylimidazolium hexafluorophosphate ([BMIM]PF6), was used to prepare electrochromic poly(3‐hexylthiophene) (PHexT). Characterization of the resulting polymer was performed by cyclic voltammetry and scanning electron microscopy analyses. Spectroelectrochemistry and electrochromic properties were also characterized using various experimental techniques in the same pure ionic liquid. The thin film of PHexT was orange red in its fully reduced state. After oxidization of the undoped polymer, the film underwent a reversible change to the blue form. The PHexT film exhibited high chromatic contrast (40%), comparative switching time (2.5 s) and great electrochromic efficiency (230 cm2/C). A PHexT‐based electrochromic device was constructed and its electrochromic properties were also investigated in this paper. |
