Tungsten Oxide Applied for Electrochromic Film

Tungsten oxide may be used to produce electrochromic film, and then a new type of energy-saving window – smart window can be assembled with such an electrochromic thin film. With the development of economy and the improvement of people's living standards, people are increasingly aware of the importance of natural environment. Therefore, people hope to reduce the indoor temperature while save energy.

And at this sometimes people may want to know more about electrochromism. So, what is the history of electrochromism? It is reported that the concept of electrochromism was first proposed by Platt, and the electrochromic phenomenon has caused widespread concern. From the mid-1970s to the early 1980s, the study of electrochromic phenomena was mostly limited to electronic display devices and their response time. During this period, American scientists and Swedish scientists proposed a new energy-saving window based on electrochromic film, called smart window. And the concept of smart window is considered to be a milestone in electrochromic research.
