POLY(ARYL PIPERIDINIUM) COPOLYMER IONOMER GRAFTED WITH PROPARGYL GROUP, CROSS-LINKED ANION-EXCHANGE MEMBRANE, AND METHOD FOR PREPARING SAME

The present disclosure 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 bond in the polymer backbone; an anion-exchange membrane cross-linked therefrom, and a method for preparing the same. The poly(aryl piperidinium) copolymer ionomer grafted with the 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 the interaction between the ionomer and the membrane and stabilizing the catalyst layer to remarkably improve the durability of a fuel cell.
