Electrochromic film and preparation equipment thereof

The utility model discloses an electrochromic film and preparation equipment thereof, and mainly relates to the field of functional materials. The electrochromic film provided by the utility model has good electrochromic performance; according to the thin film preparation equipment, a precise coating method (including but not limited to slit coating, micro-concave coating and the like) is adopted for coating, the coating thickness of an electrolyte layer can be accurately controlled, coating is more uniform and stable, and the product quality is improved; after the WO3 thin film is coated with the electrolyte layer, the WO3 thin film can be compounded with the NiOx thin film to directly obtain the electrochromic film, so that the pollution time of the electrolyte layer is shortened, the product quality is improved, and the production cost is reduced. Therefore, the electrochromic film and the preparation equipment thereof provided by the utility model have important industrial popularization and application v
