Abstract

Abstract:

In order to study the effects of the addition of CdS nanoparticles and the number of composite film layers on the electrochromic properties of tri-vanadium substituted Dawson-type tungstate 1-K₉P₂W₁₅V₃O₆₂·18H₂O(P₂W₁₅V₃) polyoxometalate composite films, composite films constructed by P₂W₁₅V₃ and CdS nanoparticles were prepared by layer-by-layer self-assembly method. The structure and properties of the composite films were characterized by UV-Vis spectroscopy, XRD, SEM and cyclic voltammetry, and electrochemical workstation and UV-visible absorption spectroscopy were used to investigate the electrochromic properties of composite films with different layers and with or without CdS nanoparticles in the voltage range of -1.0—+1.0 V. The results show that the perfomanc of 20-layer composite film is the best, for which the optical contrast is 38.05%, response time for recolorstion and bleaching are 3.57 and 6.94 s, respectively, the maximum coloring efficiency is 94.04 cm²/C, compared with the P₂W₁₅V₃ film, the optical contrast increases by 46.07% and the color efficiency increases by 96.53%, the electrochromic performance is improved remarkably.
