Title:
POLY(ARYL PEPERIDINIUM) COPOLYMER IONOMER GRAFTED WITH PROPARGYL GROUP, CROSS-LINKED ANION EXCHANGE MEMBRANE, AND METHOD FOR PREPARING SAME
Document Type and Number:
WIPO Patent Application WO/2024/096396
Kind Code:
A1
Abstract:
The present invention relates to: a poly(aryl piperidinium) copolymer ionomer which is grafted with a propargyl group, contains a piperidinium group, and does not have any aryl ether bonds in the polymer backbone; an anion exchange membrane cross-linked therefrom; and a method for preparing same. The poly(aryl piperidinium) copolymer ionomer grafted with a propargyl group has excellent chemical and thermal stability, ionic conductivity, mechanical properties, dimensional stability, and durability. In addition, the cross-linked anion exchange membrane prepared therefrom is greatly improved in the peel strength of the catalyst layer, thus promoting interaction between the ionomer and the membrane and stabilizing the catalyst layer to remarkably improve the durability of a fuel cell.
