WINDOW FILM AND PREPARATION METHOD THEREOF

摘要

A window film, comprising: a flexible transparent substrate; a first metal target material film disposed on the surface of the flexible transparent substrate; a first high refractive index compound film disposed on the surface of the first metal target material film; a first metal oxide film disposed on the surface of the first high refractive index compound film; a first silver-containing metal film disposed on the surface of the first metal oxide film; a second metal target material film disposed on the surface of the first silver-containing metal film; a second high refractive index compound film disposed on the surface of the second metal target material film. The window film has better adherence, and is less likely to peel off. Moreover, the window film also has better oxidation resistance, and is less likely to be oxidized. Furthermore, the window film also has a better optical effect and thermal insulation effect.
