PEO-doping WO3 electrochromic film referred to the WO3 electrochromic film doped with PEO, which has obvious changes in the coloring transmittance and bleaching transmittance in the visible light region. Also, the cycle reversibility of the PEO-doped WO3 film is better. In addition, the coloring response speed and bleaching response speed of the doped tungsten trioxide film are also faster, so it can be used for the preparation of electrochromic devices and smart windows. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html Some experts…

WO3-PEO electrochromic thin film can be prepared by the following two major processes. First, prepare the sol, and then prepare the doped electrochromic film. The specific steps are as follows. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html 1.0 Preparation of sol: The tungsten powder and hydrogen peroxide are reacted in a certain ratio, and the lower layer precipitate is filtered off, and then an appropriate amount of absolute ethanol, glacial acetic acid, and PEO are added, stirred uniformly, and sealed for use.…

WO3 can be prepared into a WO3 film, and then be applied for the production of a new electrochromic device. Wherein, the WO3 electrochromic film is the typical representative of the earliest and most studied cathode electrochromic material. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html Experts say that the electrochromic device is a typical optoelectronic device that combines an electronic film with an optical film. By applying a lower external voltage to the device, a reversible change in color can be achieved.…
