Description

technical field [0001] The invention belongs to the technical field of electrochromism and relates to a conductive substrate, in particular to a conductive substrate, a preparation method thereof and an electrochromic device. Background technique [0002] Electrochromism refers to the reversible discoloration of materials under the action of an electric field. The essence of electrochromism is an electrochemical oxidation-reduction reaction. After the reaction, the material shows a reversible change in color in appearance. Electrochromic materials refer to materials that can change color under the action of an external electric field and current. The essence is that the chemical structure of the material changes under the action of an electric field, which in turn causes changes in the absorption spectrum of the material. [0003] Electrochromic materials with practical value must have the characteristics of reversibility of color change, convenience and sensitivity of colo...
