Ultra thin coating makes smart glass possible and does not require electricity
according to foreign media new atlas, there are already energy-saving "smart glass" that can shield the heat rays from the sun in some ways, thereby reducing the need to operate the air conditioning system. However, such a system still needs electricity to operate. Now, scientists from the Royal Melbourne Institute of technology in Australia have developed a coating that can make existing glass smart without electricity
more than 40 million self regulating profits and taxes. The coating is composed of relatively cheap vanadium dioxide, with a thickness of only nm. This is about 1000 times thinner than a human hair
at surface temperatures below 67 ℃, vanadium dioxide can act as an insulator, helping to prevent indoor heat from being dissipated through the glass - while also allowing the full spectrum of the sun to enter the full spectrum from the outside. However, at temperatures higher than 67 ℃, it turns into a metal that blocks the entry of infrared solar radiation caused by heat
this means that when the temperature is low, the room will be warmer, while when the temperature is high, the room will be cooler, which can reduce the use of heating and air conditioning systems. In addition, users can also use the dimmer switch to cover the light blocking effect of the coating
previously, in order to apply a vanadium dioxide coating, a special layer or platform must be created on the surface. However, the RMIT team has developed a method of coating directly on the surface of glass without the need for a platform. Now the research team hopes that the system can be commercialized as soon as possible
professor Madhu bhask, the chief scientist, developed cold chain logistics Aran, said: "our technology will likely reduce the rise in air conditioning and heating costs, and significantly reduce the carbon footprint of various buildings. Our energy crisis solution comes not only from renewable energy, but also intelligent technology that can eliminate energy waste is absolutely crucial."
