Title:
COMPOSITE ELECTROCHROMIC MATERIAL, AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/194125
Kind Code:
A1
Abstract:
A composite electrochromic material, and a preparation method therefor and an application thereof, the material comprising a core layer, a skin layer having an electrochromic function, and a light-transmitting protective layer formed by a flexible polymer material, that are arranged in sequence. The material of the core layer comprises a fluid conductive mixture, and the conductive mixture comprises liquid metal and carboxylated carbon nanotubes. The preparation method comprises: carrying out spinning by co-extrusion using a three-channel nozzle to form hollow double-layer fibers each having a skin layer and a protective layer as well as a cavity, and injecting the conductive mixture into the cavities of the hollow double-layer fibers. The material has excellent deformation ability, stable and sensitive color changing function, and a controllable deformation degree. The material has a stable color changing function even in the case of severe deformation, has good fatigue resistance, and is suitable for the preparation of intelligent textiles.
