Nanometer yellow tungsten oxide may be used to produce transparent thermal insulation nanopowder. In fact, the nanopowder is not transparent. But, thermal insulation film using nano grain size yellow tungsten oxide as raw material is transparent. Besides, yellow tungsten oxide is also a typical representative of inorganic electrochromic materials. At present, electrochromic devices using yellow tungsten oxide as dingal material have been industrialized.
In practical applications, especially in the preparation of electrochromic devices, electrochromic materials meet the following requirements generally: Stable chemical properties; high cycle life; fast color change response; reversible color change; highly sensitive to color change. It should also have a certain storage memory ding and good electrochemical redox reversibility.
The so-called electrochromic material refers to the material that can undergo reversible color change under a lower driving voltage or current, which causes the valence state and composition of the material to undergo a reversible change, so that the optical properties of the material are changed or maintained.
