In the prior art, electrochromic method is mostly used to change the color of glass to improve the aesthetics and aesthetic value of glass, but it can only be applied to electrified glass, which has limited service life, is difficult to be widely used and wastes energy. The patent with the application number of CN 105607374A manufactures electrochromic glass, in which a transparent conductive layer, an electrochromic layer, a lithium oxide electrolyte layer and an ion storage layer are sequentially deposited on a glass substrate. Compared with the traditional electrochromic glass, the color change rate and color change range are improved, but it still can't change color without the action of external electric field, and there is great resistance to its wide popularization.
The invention can effectively improve the surface hardness and corrosion resistance of glass, reduce indoor and outdoor heat exchange, and can generate redox reaction through the change of wavelength and frequency of light. As long as the plated metal is not damaged, the color will always change without any external electric field, and the reversibility and fatigue resistance are good, so that the glass has good daylighting rate.
