Abstract

The invention relates to an edge sealing conductive substrate and an electrochromic device. The edge sealing conductive substrate comprises a substrate layer, a transparent conductive layer, at leastone conductive part, at least one sealing part and at least one side extraction electrode connected to the conductive part; the transparent conductive layer is laminated on the top surface of the substrate layer; the conductive part is connected to the transparent conductive layer; and the sealing part is connected to the top surface of the transparent conductive layer. The electrochromic device comprises a first conductive layer, a color-changing material layer and a second conductive layer which are sequentially arranged in a stacked mode; and the color-changing material layer is separatelyconnected to the transparent conductive layers of the first conductive layer and the second conductive layer, and the sealing parts of the conductive layers are used for sealing the edge of the color-changing material layer.

Description

technical field [0001] The invention belongs to the technical field of electrochromism, relates to a conductive substrate, in particular to an edge-sealed conductive substrate 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 color change, controllab...
