Title:
NOVEL POLYFLUORENE-BASED CROSS-LINKED COPOLYMER, METHOD FOR PRODUCING SAME, AND ANION EXCHANGE MEMBRANE FOR ALKALINE FUEL CELL USING SAME
Document Type and Number:
WIPO Patent Application WO/2022/131665
Kind Code:
A1
Abstract:
The present invention relates to: synthesizing an aromatic polyfluorene-based copolymer which has a cross-linked structure and does not have an aryl ether bond in the polymer skeleton, and in which a piperidinium group is introduced in a repeating unit; producing an anion exchange membrane from the copolymer; and applying the anion exchange membrane to an alkaline fuel cell, water electrolysis, carbon dioxide reduction, a metal-air battery, etc. According to the present invention, an anion exchange membrane having a cross-linked structure has excellent thermal/chemical stability and mechanical properties, as well as high water-holding capacity, ionic conductivity, and durability, and exhibits an excellent dispersed phase.
