WO3 nanorod array film is an important electrochromic material. Some experts have prepared such an electrochromic film by replacing the conventional WO3 seed layer with a TiO2 seed layer that is matched with the FTO lattice. The prepared tungsten trioxide electrochromic film has a large light modulation range, high coloring efficiency, and significantly improved cycle stability.

Why is the seed layer the focus of current research? This is because the dense seed layer not only generates energy consumption due to annealing treatment during the preparation process, but reduces electron transport efficiency in the electrochromic process, so excessive energy consumption is generated in application. In addition, the seed layer is cumbersome to prepare. And the uniformity of the seed layer directly affects the uniformity of the prepared tungsten trioxide electrochromic film, thereby affecting its electrochromic properties. Therefore, the research of seed layer has become the focus of current research for the production of tungsten trioxide thin film.
