摘要
电致变色材料具有可逆的颜色转变特性,在智能窗、显示器、防眩后视镜、电子纸、军事伪装等领域应用广泛。相对于其它种类的显示器件,电致变色显示器件具有色彩丰富、对比度高、无视盲角、断电后仍显色等优点。作为一种典型的阴极着色电致变色材料,氧化钼具有响应时间短和着色态更接近于人眼对光线的敏感波段等优点,使得由氧化钼组成的电致变色器件具有重要的研究价值。本文简要介绍了电致变色、电致变色材料与器件的定义及其应用,尤其电致变色技术最近在智能手机上得到了示范应用,表明电致变色技术未来有良好的发展前景。然后,详细综述了氧化钼薄膜的制备、氧化钼的改性、氧化钼电致变色器件的研究进展。最后提出了氧化钼电致变色薄膜与器件当前存在的问题和解决的途径,并对其发展前景进行了展望。
Electrochromic materials show reversible color-changeable characteristics,which are widely used in smart windows,displays,adjustable reflective mirrors,electronic paper,military camouflage and other fields.Compared with other kinds of display devices,electrochromic display devices have advantages of multi-colors,high contrast,no blind visual angles,and maintainable color after power off.As a typical cathodic colored electrochromic material,molybdenum oxide exhibits advantages of short response time and colored state closer to the sensitive wavelength band of the human eye to light,so that the electrochromic devices composed of molybdenum oxide is important in the research.This paper briefly introduces the definitions and applications of electrochromism,electrochromic materials and devices.In particular,electrochromic technology recently realized a demonstration application in smart phones,indicating the good prospects for the future development of electrochromic technology.We summarized mainly the research progress of the preparation of molybdenum oxide films,the modification of molybdenum oxide,and the molybdenum oxide based electrochromic devices.Finally,we presented current existing problems and solutions to molybdenum oxide based electrochromic films and devices with development prospects.
