Investigation of the properties of modified sulfonated poly (Ether sulfone) copolymers as fuel cell membrane via crosslinking

Two-series of sulfonated copolymers of poly (ether sulfone) of bisphenol-p and bisphenol-m, with diflourodiphenyl sulfone (DFDPS) and 3,3- disodiumsulfonyl-4,4#-diflourodiphenyl sulfone (SDFDPS) were synthesized. In order to study the effect of crosslinking on the properties of the final polymers, these copolymers were crosslinked using sulfone bond as the photo-initiator. Physical, mechanical, and thermal properties of the uncrosslinked and crosslinked polymers were studied and compared.
