Electrochromism refers to the phenomenon that the optical properties of materials (reflectivity, transmittance, absorptivity, etc.) change stably and reversibly under the action of an applied electric field. It is a reversible change of color and transparency in appearance. Materials with electrochromic properties are called electrochromic materials. Electrochromic materials are a new type of functional materials, which are widely used in information, electronics, energy, architecture and so on.

1. Electrochromic glass can insulate 99% infrared ray and 99% ultraviolet ray. It has good performance in heat insulation and sunscreen.
2. Electrochromic glass can effectively prevent indoor precious cultural relics, furniture and carpet from fading and aging.
3. The application of electrochromic glass in medical buildings can increase the recovery speed of patients by 20%.
4. The use of electrochromic windows in school buildings can reduce glare, improve students' reading comprehension ability and test accuracy by 30%.
5. By using electrochromic window, the energy consumption of air conditioner can be reduced by 30% and the installed power of air conditioner can be reduced by 25%.

Electrochromic glass is suitable for glass curtain walls of museums, sunshine rooms, airports, daylighting roofs, passive rooms, high-end business buildings and large shopping malls.
