Abstract
Using sol-gel method and dipping coating process, Tetrabutyl titanate and glacial acetic acid were added to the solvent absolute ethanol and boric acid, deionized water, nitric acid and other raw materials were added. B3+ doped TiO2 film was successfully prepared on ITO glass, The optical properties and electrochromic properties of B3+ doped TiO2 films were studied by means of TG-DTA, XRD, UV-Vis, SEM, and electrochemical workstation. The results show that the spectral control range of B3+ doped TiO2 film is significantly improved, The electrochemical cycling stability of the film is also improved. When the volume fraction of B3+ is 9%, the electrochromic effect is best.
