Hydrocarbon based BPSH-BPS Multiblock Copolymers as Novel Proton Exchange Membranes

There have been growing evidences, both experimental and theoretical, that block copolymer systems with well-defined sulfonated regions may provide enhanced transport of protons, especially at low relative humidity. We have recently demonstrated a novel way to make nearly all hydrocarbon, hydrophobichydrophilic block copolymers. The chemical structure and chemical composition are very similar to BPSH copolymers. However the microstructure and the morphology are very different. This paper will try to unfold the structure property relationships of the multiblock copolymers for application as potential proton exchange membranes. Introduction
