Japan developed "smart" glass

Japan's Fuji XEROX Corporation announced that it has successfully developed "smart" glass that adjusts transparency based on temperature changes. It is reported that this newly developed "smart" glass will have less transparency when the temperature rises, and will have greater transparency when the temperature drops. This glass is used in the windows of buildings to improve the working efficiency of air conditioners and achieve energy saving. The structure of the "smart" glass is actually filled with a pigmented polymer microparticle between two glass layers. This tiny particle can change its volume with the change of temperature. When the temperature rises, its volume can be increased by a maximum of 30 times. When the temperature decreases, it can be restored to its original shape. "Smart" glass is less transparent when the temperature exceeds 30 degrees Celsius, and can block 80% of the light; if the temperature is below 30 degrees Celsius, 80% of the light can pass. The degree to which the air temperature exceeds the maximum does not begin to be shaded. This can be set by processing the material itself. Japan has developed glass that uses electricity to regulate light. In 2000, the world's market for dimmable glass reached 200 billion yen, and in Japan alone it reached 130 billion yen. Compared with dimming glass, the smart glass developed this time has a simpler structure and the cost is only 1/4 of that of dimming glass. A survey in Japan has found that 15% of the heat in office buildings that use air conditioners is the sunlight coming through the windows. If you use this "smart" glass, you can save energy. Fuji XEROX plans to put this "smart" glass on the market two years later.
