We prepared anion-exchange membranes based on -ray crosslinked ethylene-tetrafluoroethylene copolymer (ETFE) by -ray-induced graft polymerization of chloromethylstyrene (CMS) and the subsequent quaternization reaction. Little effect of radiation crosslinking was observed for the degree of CMS grafting and the quaternization ratio. Interestingly, however, the crosslinking structure in ETFE was found to lower water uptake of the resulting membranes in the OH form, thereby restricting excessive swelling during hydrazine-fuel-cell operation.
