摘要:

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.

Abstract:

WO3 nanoblocks were prepared by hydrothermal method on FTO glass, and WO3/Ag composite film was prepared by electrodepositing different content (20 s, 50 s, 80 s) of Ag nanoparticles onto WO3 nanoblocks. Characterization of WO3/Ag composite films was confirmed by X-ray diffraction analysis, scanning electron microscopy and energy spectroscopy. The parameters of electrochromic reversibility, response time, coloration efficiency and spectral transmittance were obtained by electrochomical measurement technologies and spectral tests. Then, the electrochromic properties were analyzed. The WO3/Ag composite films show the higher electrochromic properties compared with the WO3 nanoblock film. The effects of different Ag nanoparticle content on the electrochromic properties of WO3/Ag composite films were also studied. The results show that the WO3/Ag composite film deposited for 50 s has the best electrochromic properties.

Key words: Electrochromic, WO3/Ag composite films, Electrochomical measurement, WO3 nanoblocks, Spectral test
