Yellow tungsten oxide, or tungsten trioxide, has excellent electrochromic property, that is, thermal insulation property, so it can be applied to building thermal insulating glass in the form of a heat-insulating film. So, how to apply tungsten trioxide nano particles to architectural glass? The electrochromic glass can be prepared by a coating process.

For the coating process, experts have introduced that, in recent years, nano-ink technology is expected to replace the vacuum coating process, and therefore it has attracted much attention of researchers. Nano-ink technology includes the preparation of high quality nano-inks and the research of nano-ink film-forming processes. Although researchers have done a lot of work on nano-inks, how to apply nano-ink technology to electrochromic electrodes is still a topic that needs further study. In other words, it requires further research on applying the nano-ink technology to electrochromic film of nano particle size tungsten trioxide.
