摘要
三氧化钨(WO_(3))是最早被发现的阴极电致变色材料,具有光学调制幅度大、驱动电压低、循环稳定性好等优点,受到国内外研究者的广泛关注.WO_(3)薄膜在智能调光窗、玻璃幕墙和防眩反光镜等诸多领域有着广阔的应用前景.目前,改善全器件的响应速度、循环稳定性等综合性能仍是电致变色WO_(3)薄膜大规模产业化急需解决的问题.文章介绍了多种WO_(3)薄膜电致变色机理,概述了WO_(3)薄膜的主要制备方法,重点综述了提升WO_(3)薄膜电致变色性能的两种方法:构筑纳米结构和掺杂(金属元素和复合改性)以及近几年利用这两种方法制备WO_(3)电致变色薄膜的相关工作.最后,文章对该领域未来的研究方向和应用前景进行了展望.
Tungsten trioxide(WO_(3))is the first cathodic electrochromic material discovered.It has the advantages of high optical modulation amplitude,low driving voltage and good cycle stability,and has attracted extensive attention from researchers at home and abroad.Tungsten oxide film has broad application prospects in many fields such as intelligent dimming window glass curtain wall and anti-glare reflectance mirror.At present,improving the response speed and cycle stability of the whole device is still a problem that needs to be solved in the large-scale industrialization of electrochromic tungsten oxide film.The article introduces several electrochromic mechanisms,summarizes the preparation methods of WO_(3)thin films,and focuses on two methods to improve the electrochromic properties of WO_(3)thin films:nanostructure construction and doping(metal elements and composite modification),and the preparation of WO_(3)electrochromic films by these two methods in recent years.Finally,the future research directions and application prospects in this field are also prospected.
