Nano tungsten trioxide is a functional material that has special optical properties, including high shielding ratio in the infrared and ultraviolet regions and high transmittance in the visible region, so it can be used for the preparation a new type of energy saving glass coating - thermal insulation coating. And the obtained coating not only has the function of shielding infrared rays and ultraviolet rays, but also has the advantages of high visible light transmission and environmental protection.

Yellow tungsten oxide may be used to prepare an energy saving glass coating, which is applied to glasses of buildings such as glass doors and windows, glass curtain walls, and glass windows of airplanes, automobiles, trains, ships, and the like.

Tungsten oxide may be applied to prepare an energy saving glass coating, which has been developed to shield infrared light and ultraviolet light in sunlight while maintaining high visible light transmittance in recent years. This new nano heat insulation coating has the following advantages:

WO3 may be used to prepare an energy saving glass coating, which is a new environmentally friendly thermal insulation coating. That is to say, the appearance of transparent heat insulating coating provides a new direction for the heat insulation problem of building glass. Therefore, tungsten oxide and tungsten oxide thermal insulation coating prepared therefrom have a good application prospect in the field of architectural glass.
