| Summary: | TiO<sub>2</sub> nanowires were prepared on fluorine-doped tin oxide(FTO) glass by hydrothermal synthesis, and then the MoO<sub>3</sub>/TiO<sub>2</sub> composite films were prepared by electrodepositing MoO<sub>3</sub> films onto TiO<sub>2</sub> nanowire arrays. The parameters such as diffusion coefficient(<i>D</i>), the responding time of colored and bleached, optical density(ΔOD), electrochromic reversibility and coloration efficiency of MoO<sub>3</sub>/TiO<sub>2</sub> composite film were obtained by electrochromical measurement technologies and spectrum tests. The effect of TiO<sub>2</sub> nanowire substrates with different hydrothermal growth time on the electrochromic properties of MoO<sub>3</sub>/TiO<sub>2</sub> composite films was studied. The results show that the MoO<sub>3</sub>/TiO<sub>2</sub> composite films with 6 hours of hydrothermal growth TiO<sub>2</sub> nanowires have the best electrochromic properties. The diffusion coefficient is 2.86×10<sup>-12</sup> cm<sup>2</sup>·s<sup>-1</sup>, the cyclic reversibility is 60.88%, the optical density is 0.41, the coloring efficiency reaches 124.49 cm<sup>2</sup>·C<sup>-1</sup>, and its responding time of colored and bleached is 13.53 s and 12.65 s. |
