Abstract
通过水热法在导电玻璃上合成WO3纳米块，利用电沉积技术在WO3纳米块上负载不同含量（20 s、50 s、80 s）的Ag纳米粒子，成功制备出WO3/Ag复合薄膜.通过X射线衍射分析、扫描电子显微镜与能谱对WO3/Ag复合薄膜进行表征，利用电化学测试与光谱测试，得到电致变色可逆性、响应时间、着色效率和光谱透过率等参数，并对其电致变色性能进行分析.结果表明，对比单一WO3纳米块薄膜的电致变色性能，WO3/Ag复合薄膜的电致变色性能显著增强.同时研究了不同Ag纳米粒子含量对WO3/Ag复合薄膜电致变色性能的影响，研究表明沉积50 s的WO3/Ag复合薄膜具有最优异的电致变色性能.
