Tungsten trioxide can be prepared into an electrochromic film. And when such a film is applied to the glass curtain walls of office. It is an office thermal insulating film. Well, how to synthesize the raw material - tungsten trioxide nanoparticles?

Tungsten trioxide for preparing dining room thermal insulating film is often doping an element to produce a tungsten bronze structure, which in turn exhibits broadband near-infrared (NIR) absorption properties. And the developed general structure of tungsten bronze materials is MxWO3, where M = Cs, Rb, K, Na, and NH4.

Tungsten trioxide for exhibition hall thermal insulating film is WO3 doping with an element. That is MxWO3, which further enhances the optical absorption of tungsten trioxide powder in the solar spectrum. MxWO3, such as CsxWO3, has attracted considerable attention because it offers a wide variety of crystal structures and has many interesting attributes such as electrochromic, optical-electrical, and superconductive properties.

Tungsten trioxide, or WO3, is a near-infrared absorbing photothermal material, which is also known as NIR-absorbing photothermal material or PTM. And it is reported that tungsten trioxide nano particles may be applied for preparing hotel thermal insulating film.

Tungsten trioxide, or WO3, is a main functional material for preparing windshield thermal insulating film. There are a few methods for the preparation of tungsten trioxide powder such as electrochemical processes, solution-based colloidal approaches, bioligation processes and chemical vapor deposition techniques.

Tungsten trioxide for preparing glass curtain wall thermal insulating film are often tungsten trioxide nano particles doping with other elements. And these elements may be alkali metal elements or rare earth elements.

Tungsten trioxide for preparing nano heat insulating film is a new type of near-infrared absorbing material that has gained research interest. You know, the near-infrared (NIR) irradiation has a broad wavelength in the range of 780-2,500 nm.

Tungsten trioxide nanopowder applied for preparing explosion-proof heat insulation film is nano particle size tungsten trioxide doping with alkali metal element. And the film can satisfy the requirements of high heat shielding capability and high transparency.

Tungsten trioxide nanopowder with alkali metal element doping is widely used in the preparation of nano heat insulating film due to its excellent visible light transmittance and near-infrared light absorption properties. Wherein, the obtained transparent heat-shielding film has a transmittance of ultraviolet light of less than 1%, a transmittance of near-infrared light of less than 15%, and a transmittance of visible light of more than 70%.

Tungsten trioxide doping with alkali metal element is mainly applied for preparing a study thermal insulating film – a transparent heat-shielding film that can shield against infrared light. The infrared light shielding ability of such a smart film is excellent and the visible light transmission is greater than 70%.
