Tungsten trioxide can be applied for the preparation of smart window as WO3 has the advantages of high electrochromic color contrast, good cycle stability and good thermal stability. And therefore tungsten trioxide nano particles have become the most researched and commercialized inorganic electrochromic material in recent years. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html The smart window was proposed by American scientist C.M.Lampert and Swedish scientist C.G.Granqvist in the 1980s. At the time, they proposed an electrochromic device with a “sandwich” structure…

Tungsten oxide smart window has excellent energy saving effect. According to statistics, if such new type of smart glass is used in glass curtain wall, it can reduce the operating cost of the building by 20%, including reducing its peak demand for electricity by 24%, reducing the load on the HVAC system by 25%, and reducing the lighting cost by 60%. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html Experts say that this kind of smart window adopts electrochromic technology. They also said…

Tungsten oxide smart glass not only can adjust the transmittance in the visible light region, but also has a shielding effect on the infrared light in the colored state. This is because the electrochromic glass of tungsten oxide nano particles can actively block the heat loss caused by the indoor and outdoor temperature difference and reduce the energy consumption caused by building cooling and heating. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html Experts say that the term electrochromism was first proposed by…

Mo doped WO3 electrochromic film has much similar electrochromic properties as the WO3 electrochromic film. As you may have known, tungsten trioxide electrochromic film has been more and more widely used in building glass. Thus, the Mo-doped WO3 electrochromic film has also become a hot spot of current research. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html Some experts have studied the electrochromic properties of Mo doped tungsten trioxide electrochromic film.

By doping (Ti), the tungsten trioxide electrochromic material can be improved in response time, coloring efficiency, color…

WO3 based electrochromic film has excellent intelligent dimming ding. As you may know, in order to improve the coloring efficiency of traditional tungsten trioxide electrochromic materials and devices, it is often necessary to implant ions and electrons deep into the tungsten trioxide material. Besides, due to the poor conductivity of tungsten trioxide itself, its electrochromic response times tend to be longer. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html Therefore, in order to shorten the response time of tungsten trioxide based electrochromic materials,…

Tungsten trioxide based inorganic electrochromic film can be prepared by an inkjet printing film forming process. As you may have known, with the rapid development of electronic devices, printing electronic technology has increasingly become the focus of academic field and industrial circles.
