WO3 thin film is promising in the application of electrochromic smart window as WO3 is the most studied electrochromic material of significance. Some researchers have adopted sol-gel spin-coating method to deposit WO3 thin films on indium tin oxide (ITO) coated glasses.

Doped tungsten oxide is an active material for the absorption of radiation in the near infrared wavelength range so that it is often used as a near-infrared absorber in the production of heat insulation coating for obtaining energy efficient window/ smart window. Wherein, doped tungsten oxide may be cesium doped tungsten oxide, which is also known as cesium tungsten bronze with the formula of CsxWO3.

Tungsten oxide film is designed to fabricate electrochromic window, which is also called smart window. Some researchers have adopted a spin-coating technique to deposit tungsten oxide (WO3) film by using sol-gel peroxotungstic acid sol. And the prepared tungsten oxide thin film was used to produce smart window.

Nanocrystalline tungsten oxide is an important electrochromic material for producing electrochromic coating. It has been reported that nanocrystalline tungsten oxide electrochromic coating with excellent cycling stability can be prepared via a complexation-assisted sol–gel method. For the preparation process, a small amount of dopamine is added into the peroxotungstic acid precursor sol to form complexes with tungsten on the surface of peroxotungstic acid colloidal nanoparticles to enhance the electrochromic performance of WO3 coating, especially the electrochemical cycling stability.

Yellow tungsten oxide nanoparticles, or tungsten trioxide nanoparticles, or WO3 nanoparticles, may be applied to prepare building glass thermal insulation coating. Also, WO3 nano powder is of interest as an oxidant for metals in metastable intermolecular composites, which is useful for such applications as electric matches and gun primers.

Nano tungsten oxide for preparing glass heat insulation coating is a new type of functional nano material. It has been reported that such glass heat insulation coating can be obtained by using high-tech nanomaterial technology to apply a micron-scale nano tungsten oxide coating layer on the glass surface. And the architectural glass will achieve the purpose of high heat insulation in hot summer and prevent the indoor heat from being dissipated to the outside in the cold winter, while ensuring high visible light transmittance, and ultimately achieving the goal of high efficiency and energy saving.

Nano tungsten oxide is well-known as it is the most important functional material for producing new energy-saving glass coating with high heat insulation and heat preservation. Well, do you know why nano tungsten oxide can be produced by wire explosion process?

Nano tungsten oxide for preparing nano heat insulation material such as heat insulation film may be high-purity yellow tungsten oxide nano powder with the characteristics of excellent heat shielding, UV-proof performance, good dispersibility and dispersion stability. It is reported that such a new type of nano thermal insulation material has the absorbing and reflecting abilities of near-infrared wavelengths in the 800-1000nm region and ultraviolet rays below 380nm.

Nano tungsten oxide for preparing nano heat insulation coating is usually nano aqueous heat insulation dispersion of tungsten oxide nano particles. Experts said that the prepared nano heat insulation coating is an environmentally friendly functional material that can shield most of the solar heat radiation and ultraviolet radiation to reduce the temperature inside buildings and cars and improve human comfort.

Nano tungsten oxide is a kind of heat insulation medium that may be used to prepare nano heat insulation dispersion with a blue liquid appearance. Such a transparent dispersion solution has good absorption effect on ultraviolet and near infrared rays, especially the shielding performance in the near infrared region is far greater than ATO and ITO.
