Smart Window

More precisely, a new generation of glass makes the window of the house flexible with the sun. In the morning, the glass will be dim when it is cold or when the window glass will quickly switch to transparent.

This new material reduces the cost of cooling in the summer and warms it up in the winter. South Korean scientists and coauthors of the ACS Nano journal say that the new material will have a very large market, from roof glass to windows and even glass. steam.

Hitachi recently pioneered the use of this technology to produce SPD smart lenses for use in homes, while Mercedes-Benz is racing to research the same type of automotive glass. . Hitachi's new factory is capable of producing high-performance, cost-effective SPD glasses, so it is difficult for other manufacturers to enter the market. According to the Daily Mail , previously had similar smart windows, but the price is too high and use some toxic chemicals in the production process, so it was not commercially successful.

Scientists have revealed that this smart glass uses a polymer-based material with an active layer of activated carbon and ethanol, making it cheaper, less toxic, and more stable in harsh environments. Another advantage of smart glass is the aesthetics, the flexibility to switch environment adaptation mode in just a few seconds.
