Problems solved by technology

[0004] However, in the existing electrochromic glass, the ion conductor layer and the ion storage layer are mostly made of liquid electrolyte and organic polymer electrolyte, which have a certain corrosion effect on the adjacent film layer, and the ion is easy to diffuse. Therefore, its service life and coloring stability are not ideal
Furthermore, the existing electrochromic glass preparation process is complicated to control and the manufacturing cost is high, which also limits the development of electrochromic glass to large-area and industrial applications.

Description

technical field [0001] The invention relates to an energy-saving glass and a preparation method thereof, in particular to an all-solid thin-film electrochromic glass and a preparation method thereof. Background technique [0002] Electrochromic (Electrochromic, EC) refers to the phenomenon that the optical properties of materials undergo continuous and reversible changes under the action of an external electric field, which is intuitively manifested as a process in which the color and transparency of materials undergo reversible changes. Electrochromic glass can selectively absorb or reflect external heat radiation and prevent internal heat diffusion, reducing the large amount of energy that office buildings and residential buildings must consume to keep cool in summer and warm in winter. The electrochromic energy-saving window made of electrochromic glass can realize the sub-band automatic regulation of light and heat in almost all bands related to comfort and energy saving...
