Title:
POLYFLUORENE-BASED ANION EXCHANGE COMPOSITE MEMBRANE AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2022/131666
Kind Code:
A1
Abstract:
The present invention relates to a technology for manufacturing an anion exchange composite membrane comprising: a porous polymer support; and a polyfluorene-based anion exchange membrane or a polyfluorene-based anion exchange membrane having a crosslinked structure, formed on the support, wherein the anion exchange composite membrane is applied to alkaline fuel cells, water electrolysis, carbon dioxide reduction, metal-air batteries, and the like. The polyfluorene-based anion exchange composite membrane comprising a porous polymer support, according to the present invention, has remarkably improved mechanical properties, dimensional stability, durability, long-term stability and the like.
