over the years, the market has successively developed "smart glass" windows with energy-saving functions, which can electronically shield the solar radiation and heat rays, thereby reducing the need to operate air conditioning systems, Reduce energy consumption and carbon dioxide emissions. However, these systems often require electricity to operate. Now, scientists from RMIT in Australia have developed a new coating that can make existing glass smart without power

the new coating is mainly composed of relatively cheap vanadium dioxide, with self-adjusting function. The coating thickness is only 50 ~ 150 nm, which is about 10 times thinner than human hair. After repeated attempts and efforts with customers, it is 00 times thinner

when the surface temperature is lower than 67 ℃ (153 ℉), vanadium dioxide can act as a heat insulator, which helps to prevent indoor heat from escaping through the window glass, and also allows all visible light from the outside but from the overall level of production capacity. However, when the surface temperature is higher than 67 ℃, the coating usually claims to reach the new national standard flame retardant B1 grade material, which will be transformed into a metal layer to prevent the solar infrared radiation that generates heat from entering the room

this means that when the temperature is low, the room will remain warm, while when the temperature is high, the room will become cooler, which can effectively reduce the use of heating and air conditioning systems. In addition, if users want, they can also use dimmer switches to enhance the light blocking effect of the coating

in terms of construction, in order to apply vanadium dioxide coating, a special base or platform must be created on the surface of the material. To this end, the RMIT team specially developed a method to apply the coating directly to the surface of window glass without the need for a special base or platform. At present, RMIT is promoting the commercialization of the system as soon as possible

Professor Madhu Bhaskaran, the chief scientist of the project, said: "our technology will probably reduce the cost rise caused by the use of air conditioning and heating, and significantly reduce the carbon footprint of buildings of all sizes. This is an intelligent technology that can not only come from renewable energy, but also eliminate energy waste. It is absolutely important to the solution of the energy crisis to (5) the innovation and development of new aerospace materials in China."

this research achievement was recently published in the journal scientific reports – nature, and British scientists have also developed smart windows coated with vanadium dioxide
