摘    要:通过真空镀膜方法制备的纳米Ag薄膜均匀致密, 表面光滑. 然后通过电化学方法在Ag纳米薄膜上沉积一层三氧化钨(WO3), 制备纳米Ag/WO3复合膜. 并在此基础上构筑五层式玻璃/ITO/纳米Ag-WO3复合膜/固态电解质/聚(3-甲基噻吩)/ITO/玻璃电致变色器件. 实验结果表明, 与传统的WO3膜相比, 纳米Ag/WO3复合膜具有更好的电化学活性、更高的对比度、更短的响应时间, 以及更好的稳定性. 由该复合膜组装的电致变色器件工艺简单, 电致变色性能良好.

关 键 词:Ag/WO3纳米复合膜  聚3-烷基噻吩(PMeT)  离子液体[BMIM]PF6  电致变色器件(ECD)

Abstract:n Ag nanoparticle film, which was fabricated by a vacuum deposition method from high purity Ag wire onto cleaned ITO, was uniform and smooth. An Ag/WO3 composite film was prepared by cathodic electrodeposition of WO3 onto the surface of the Ag nanoparticle film. Moreover, an Ag/WO3 nanocomposite film based 5-layer electrochromic device (glass/ITO/Ag-WO3 nanocomposite film/solid electrolyte/poly(3-methythiophene)/ITO/glass) was constructed and its electrochromic properties were also investigated in this paper. In comparison with a single component system (WO3), a substantial enhancement in the electrochromic performance for the Ag embedded WO3 composite system was clearly observed. The method of constructing this electrochromic device was simple and its electrochromic properties appeared good.
Keywords:Ag/WO3 nanocomposite film  poly(3-methylthiophene) (PMeT)  ionic liquid [BMIM]PF6  electrochromic device (ECD)
