Abstract

The invention relates to an inorganic electrochromism ion transport layer and assembly composite film system preparation method, which is characterized in that a WO3-based film, an AlPO4-based film, a NiO-based film and a TCO layer are sequentially prepared on a glass substrate / TCO layer through a chemical liquid phase method or a magnetron sputtering method, the WO3-based film, the NiO-based film and the TCO layer are prepared through the magnetron sputtering method, and the WO3-based film, the AlPO4-based film, the NiO-based film and the TCO layer are arranged on the glass substrate / TCO layer. The ion transmission layer AlPO4-based thin film is prepared by adopting a magnetron sputtering method or a chemical liquid phase deposition method. The invention has the advantages that: a novel solid electrolyte material, namely an AlPO4-based material, is adopted as the ion transmission layer; and the AlPO4-based ion transport layer can be prepared by adopting a chemical liquid phase deposition method. Compared with a radio frequency mode needed by magnetron sputtering, the liquid phase method is lower in cost and higher in efficiency. Meanwhile, the AlPO4-based ion transport layer prepared by the liquid phase method enables the film structure to be loose and the ion mobility to be higher due to the characteristics of the preparation method, and the finally prepared assembly has higher color changing efficiency.

Description

technical field [0001] The invention belongs to the field of thin film preparation, and in particular relates to a method for preparing an ion transport layer and component composite film system for inorganic electrochromism. [0002] technical background [0003] Electrochromic components are divided into all-solid-state inorganic electrochromic, organic electrochromic, and electrodeless-organic combined electrochromic components. For future-oriented industrialization, organic electrochromic has the advantages of large color change range and fast response speed. , color is easy to control, etc., but its service life and environmental tolerance have certain defects, and the all-solid-state electrochromic component adopts all-solid inorganic materials, its service life is guaranteed to a large extent, and its color-changing performance although It is not as good as organic components, but it still has a wide range of application scenarios and space, and the market potential ...
