Yellow tungsten oxide nanopowder, namely tungsten trioxide nano powder, may be applied in smart window, as a cathode electrochromic material, more specifically, as the most widely studied cathode electrochromic material, which has the advantages of large light modulation range and better cycle stability. And such smart window glass is more and more widely used in villa for high transparency and high heat insulation.

Yellow tungsten oxide, namely tungsten trioxide, is an important smart heat insulation coating with the advantages of high heat insulation, high heat preservation and high transparency. Therefore, the new environmentally-friendly film has a wide range of applications. For example, it can be used in applications such as building doors and windows, automotive glasses, greenhouses, and so on.

Yellow tungsten oxide, or tungsten trioxide, can be used as a cathode electrochromic material on the smart heat insulation window glass. So, these glasses will have excellent heat insulation effect, thereby reducing the air conditioning refrigeration cost in the hot summer, and also achieving the purpose of energy conservation and environmental protection.

Yellow tungsten oxide, or WO3, can be used to prepare smart heat insulation film for smart windows, including building smart windows and car smart windows, which provide good heat insulation performance and high UV resistance.

Nano yellow tungsten oxide, or nano particle size tungsten trioxide, or nano WO3, can be used as a cathode coloring material for smart window, mainly in the form of an electrochromic film, which can maintain very high light transmittance in both the colored state and the bleached state. In other words, such thin film will not affect the field of view with good thermal insulation effect. Therefore, WO3 has broad application prospects in the field of electrochromic smart windows.

Mo doped tungsten trioxide nano film can be prepared by in-situ thermal oxidation spraying method. the doped tungsten oxide raw material can be prepared by a simple, green solution method. The obtained nanoparticles of a grain size of about 20nm, which can be uniformly dispersed in water to form a stable nano ink. So why to use an in-situ thermal oxidation spray technology to prepare a doped tungsten oxide electrochromic film?

Mo-doping WO3 electrochromic film may be applied in smart windows for heat insulation, that is, for energy conservation and environmental protection. So, with the promotion of the application prospect of doped tungsten trioxide in the field of smart windows, more and more experts have shown great interest in this electrochromic material.

Tungsten trioxide nanosheet can be used to prepare electrochromic film, which may be applied to building smart windows to save energy and reduce consumption. That is to say, WO3 nano particles have good thermal insulation effect that everyone cares about.

Mo-doping WO3 nanoparticles film, which may be applied in window glass for high heat insulation effect, can be prepared by the following steps: prepare the reaction precursor liquid; prepare the water-based Mo-doped WO3 nanoparticle ink; prepare the WO3 electrochromic film by spraying.

Hydrated WO3 nanosheet can be prepared by a simple, green solution process of high quality, and the prepared WO3 can be used to prepare flexible electrochromic electrode, i.e., electrochromic film, by low pressure electrodeposition method. And the obtained WO3 electrochromic film has good thermal insulating performance for applying in building window glass or car window glass.
