Quaternized poly(ether ether ketone) hydroxide exchange membranes for fuel cells
TL;DR: In this article, a quaternized PEEK hydroxide (QAPEEKOH) membrane was synthesized for the first time by concentrated sulfuric acid as the solvent and its degree of chloromethylation (DC) was controlled (38-98%) by varying the CH time.
