title: Multicolor and fast electrochromic P(DTB-EDOT)/ZnO nanocomposite film.
abstract: In this work, uniform and controllable size of ZnO nanoparticles were fabricated via solution-phase approach, and the copolymer based on the monomers of 1,4-di(thiophen-3-yl)benzene (DTB) and 3,4-ethylenedioxythiophene (EDOT) was successfully synthesized with electrochemical polymerization. A new P(DTB-EDOT)/ZnO nanocomposite film was obtained via situ preparation. Cyclic voltammogram and spectroelectrochemical characterization showed that the composite film had a stable and well-defined reversible redox process as well as electrochromic behavior. Besides, the composite film exhibited fast switching time (1 s at 746 nm), significant optical contrast and a variety of colors (red, ochre, green and blue) under different potentials.
