Tetrazole tethered polymers for alkaline anion exchange membranes

Abstract

Poly(2,6-dimethyl-1,4-phenylene oxide) was tethered with a 1,5-disubstituted tetrazole through a quaternary ammonium linkage. The formation of a tetrazole-ion network in the resulting polymers was found to promote the hydroxide ion transport through the Grotthus-type mechanism.

Key words： anion exchange membrane; fuel cell; phase separation; tetrazole
