Nano yellow tungsten oxide may be used to prepare a new smart glass coating – a transparent thermal insulation coating, which is mainly applied to building glass with excellent heat insulation effect. By spraying such environmentally-friendly thermal insulation nano-coating on the glass doors or glass windows, the obtained tungsten oxide heat insulation film has a thickness of 8-12um and a visible light transmittance of more than 85%. Therefore, the glass doors and windows of the house can be kept in a good visual appearance.

Nano tungsten trioxide may be used to prepare an energy-saving building glass thermal insulation coating, which is environmentally-friendly to shield infrared rays, ultraviolet rays and other harmful light waves.

WO3 may be applied to produce a thermal insulation coating for applying in building glass. Such coating is mainly used for heat insulation and heat preservation of glass doors and glass windows. At the same time, as the prepared coating has high transparency, indoor lighting is good. The environmentally-friendly glass coating can be applied to the architectural glasses of the southern provinces, whose main function is to shield the solar heat energy, prevent the glass from absorbing and storing a large amount of solar heat and avoid transferring more heat into the room to cause high temperature.

Tungsten oxide may be used to prepare a building glass thermal insulation coating, which is energy-saving and environmentally-friendly. It is a type of smart glass coating. It does not contain toxic and harmful substances. It does not volatilize formaldehyde, dialdehyde and other harmful gases that do harm to the human body. It reduces the indoor temperature and effectively reduces the use of air conditioner and fan. The effect of energy conservation and consumption reduction is more obvious.
