Yellow Tungsten Oxide Nanopowder Applied for Smart Window Film

Yellow tungsten oxide nanopowder may be applied for producing smart window film. The prepared film is a new environmentally-friendly heat-insulation film that may be applied to car window glass. It is safer and more practical than common film.

Compared with the current ordinary automobile film-mounted glass, the tungsten trioxide electrochromic film not only effectively avoids the problems of foaming, aging, deterioration and falling off of these heat insulation films on the market, but also avoids many disadvantages such as shielding signal. In addition, it can not only shield ultraviolet rays, but also block the infrared rays that give the skin a burning sensation to show a significant heat insulation effect. Further, the obtained heat insulating glass also has excellent visible light transmission properties. Article 11 of the National Mandatory Standard GB7258 "Safety Technical Conditions for Motor Vehicle Operation" stipulates: "The visible light transmittance of the glass such as the windshield for the driver's viewport shall be greater than or equal to 70%." At present, most of China's glass film does not meet this requirement, which not only may lead to traffic accidents, but also affect the safety of vehicles. Moreover, the price of imported film in the current film market is also very expensive. Therefore, yellow tungsten oxide heat insulating film that has a visible light transmittance of nearly 80% with higher safety and cost performance is more and more popular.
