Problems solved by technology

However, the resistance of existing transparent materials is usually high, and the transmission resistance of electrons in the conductive layer is relatively large, which leads to different speeds of gaining and losing electrons in different parts of the conductive layer. After the area changes color, the visual experience is that the color change speed of the electrochromic device is slow and the color change is uneven

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...
