Title:
NOVEL BRANCH-CONTAINING POLY(ARYL PIPERIDINIUM) COPOLYMER IONOMER, ANION EXCHANGE MEMBRANE, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/234725
Kind Code:
A1
Abstract:
The present invention relates to a poly(aryl piperidinium) copolymer ionomer which does not have aryl ester bonds in the polymer skeleton and have branch-containing piperidinium groups introduced into repeating units, having excellent chemical stability, excellent mechanical properties while having a high molecular weight, and a low expansion rate and high dimensional stability and high ionic conductivity, and a limited phenyl absorption effect. In addition, an anion exchange membrane prepared from the branch-containing poly(aryl piperidinium) copolymer ionomer is operable under low-humidity conditions and is excellent in water management, and thus can be applied to films and binders for alkali fuel cells, water electrolysis devices, carbon dioxide reduction, vanadium redox flow batteries, or metal-air batteries.
