Description

technical field [0001] The invention relates to the technical field of electronic materials, in particular to a photocurable electrolyte, an electrochromic device and a preparation method thereof. Background technique [0002] Electrochromism refers to the phenomenon that the optical properties of materials undergo stable and reversible color changes under the action of an external electric field. This phenomenon makes electrochromic materials a typical smart material, and devices made of electrochromic materials are electrochromic devices. Electrochromic devices have the advantages of bistable state, no blind angle, low manufacturing cost, wide operating temperature range, and low driving voltage. For example, the electrochromic windows used in buildings and aircraft can adjust the intensity of sunlight through the coloring degree of electrochromic materials, making the room more comfortable and energy-saving. [0003] The electrochromic device mainly includes a transpare...
