WO3 electrochromic film is a new energy-saving material that has the characteristics of thermal insulation, heat preservation and UV resistance. Therefore, such smart material can be used in energy saving reconstruction of building or aircraft portholes. So, how to prepare WO3 energy-saving thermal insulation film?

WO3, or tungsten trioxide, is an important raw material for the preparation of all-solid-state electrochromic smart window. Nowadays, the prepared smart window is widely used in construction or automobile to achieve the purpose of “warm in winter and cool in summer”. Also, such smart glass has the advantages of anti-UV, non-glare, safety and environmental protection.

Tungsten trioxide is an important raw material for the preparation of inorganic electrochromic film. The prepared electrochromic film is a good helper for achieving the function of heat insulation and heat preservation of architectural glass, automotive glass and even aircraft glass. So, do you know what is the electrochromic mechanism of a tungsten oxide film?

Tungsten trioxide can be prepared into an electrochromic film, and then be used to produce a new energy-saving window - an all-solid-state electrochromic smart window. The prepared smart window is a new type of heat insulation window with high thermal insulation performance and high heat preservation performance. So, how is this smart window made up? We can see from the structure of the electrochromic window.

Tungsten trioxide nanoparticles, as one of the most important raw materials applied in the preparation of smart window, have the characteristics of environmental protection and excellent optical properties. So, this new type of smart glass is increasingly used in the field of construction and auto. Therefore, not only the WO3 film, but also the Ti-doped tungsten trioxide electrochromic film has received much attention.

Tungsten trioxide can be used to prepare a new type of smart window, which has the advantages of safety glass, preventing glass debris from splashing when it is struck by an external force. The prepared window also has good impact strength. Besides, this smart glass has a sound-insulating performance that partially blocks noise.

WO3 nanopowder can be used to prepare a smart window or an electrochromic window. And the window can be freely adjusted according to people's needs to shield heat and ultraviolet, so the application prospect of tungsten trioxide is broad. Since the reversible electrochromism of WO3 vapor-deposited film was published by Webb in 1973, research in electrochromism has been widely done all over the world.

Yellow tungsten oxide nanopowder, or tungsten trioxide nano powder, is an important raw material for preparing an electrochromic film, which is more and more widely applied to building glass to obtain smart glass with excellent optical properties. For example, some experts have prepared WO3 films of different temperatures on FTO conductive glass by pulsed DC reactive magnetron sputtering method.

When it comes to electrochromism, you may think of Ti-doped WO3 thin film – the widely used electrochromic material for obtaining smart glass with heat insulation performance. According to experts, Ti-doped WO3 film is a transparent electrochromic film that can be coated on FTO transparent conductive glass by pulsed DC reactive magnetron sputtering at different substrate temperatures. At the same time, you may also recall the findings of the experts:

When it comes to electrochromism, many people will think of WO3 film and Ti doped tungsten trioxide film, which may be applied to building glass for cooling the room in summer and warming the room in winter. And you may know that experts prepared Ti-doped WO3 films to study the effects of different oxygen partial pressures on the structural properties of the films. You even know the specific preparation steps, just shown as follows:
