摘要
电致变色器件具有轻巧、响应速度快、可重复使用性能好、易于制备柔性器件等优点,在智能传感器、智能窗户、柔性可穿戴设备和储能设备等领域具有广泛应用.相较于易泄漏、安全性低的液态器件,全固态电致变色器件易于封装且安全性高,具有更好的综合应用性.本文首先介绍了电致变色器件的结构,详细综述了无机与有机固态电致变色器件的性能及应用,并对比分析了两者之间的优缺点.最后,从性能瓶颈、工艺难点及产业化等角度展望全固态电致变色器件的发展应用前景.
Abstract
Electrochromic devices have the advantages of lightweight,fast response speed,good reusability,and easy preparation of flexible devices.They are widely used in fields such as smart sensors,smart windows,flexible wearable devices,and energy storage devices.Compared to liquid devices that are prone to leakage and have low safety,all solid state electrochromic devices are easy to package and have high safety,making them more versatile for comprehensive applications.This article first introduces the structure of electrochromic devices,provides a de-tailed overview of the performance and applications of inorganic and organic solid-state electrochromic devices,and compares and analyzes the advantages and disadvantages between the two devices.Finally,the development and application prospects of all solid state electrochromic de-vices are discussed from the perspectives of performance bottlenecks,process difficulties,and industrialization.
