Monodisperse tungsten oxide nanorod can be prepared by solvothermal methods and then be used to produce an electrochromic film. Some experts used solvothermal method to synthesize monodisperse tungsten oxide nanorods. By adjusting the concentration of oleylamine in the precursor, the particle size of the nanorods was controlled. The grain size of the WO3 nanorods increased from 38nm x 3.2nm to 89nm x 4.5nm. The experts also heat-treated the WO3 nanorod to obtain an electrochromic thin film at a certain temperature.

Tungsten oxide may be used to prepare car heat insulation glass coating. Specifically, some experts have obtained high transparent heat-insulating glass coating with good thermal insulation effect and excellent performance to resist ultraviolet by the following steps:

Tungsten oxide may be used to prepare a new type of environmentally friendly heat insulation glass coating. Some experts weighed the mixed slurry of nano tungsten oxide and antimony tin oxide, resin and diluent by weight percentage, and then the slurry was mixed and dissolved by conventional techniques to obtain tungsten oxide heat insulation glass coating.

Ti doped tungsten oxide electrochromic film can be prepared by two main processes: The preparation of Ti-doped tungsten oxide sol and the production of Ti-doped WO3 electrochromic film by immersing the ITO conductive glass into the obtained sol and pulling. Specifically, the expert proposes a method for preparing a Ti-doped tungsten oxide film as follows:

Tungsten oxide may be used to produce electrochromic film, and then a new type of energy-saving window – smart window can be assembled with such an electrochromic thin film. With the development of economy and the improvement of people's living standards, people are increasingly aware of the importance of natural environment. Therefore, people hope to reduce the indoor temperature while save energy.

Yellow tungsten oxide may be used to produce heat insulation masterbatch so that it may have high thermal insulation with high transparency, thereby cooling the room without affecting day lighting. It is reported that the tungsten oxide thermal insulating masterbatch can be used alone or in combination with other heat insulating masterbatch of the same type. And it can be used for various plastic substrates such as PET, PE, PC, PMMA, and PVC, etc. Generally, it can be produced by mixing with ordinary plastic chips with certain added amount according to the original process.

Tungsten trioxide may be used to prepare a new type of car heat shielding coating. And such heat insulation coating is also a long-lasting hydrophilic anti-fog coating with self-cleaning performance.

Tungsten trioxide may be used to prepare heat-insulation and heat-preservation coating, which has high shielding performance to infrared rays, UV rays and other harmful light waves. So such smart heat insulation coating may be used on building glasses to help create a comfortable and healthy indoor environment. And you can enjoy your lives more comfortably.

Tungsten trioxide may be used to prepare a new type of heat shielding coating, which has high heat insulation performance and high visible light transmittance. So, such smart coating is more and more widely applied to replace curtains, heat insulation films and low-e glass and many other thermal insulating materials.

Tungsten trioxide may be used to produce a new type of environmentally friendly heat insulation coating - a smart heat insulation material that is considered to have a large application market for building energy-efficient windows and doors. But why do people think so?
