Soft Block Sulfonated Styrene-Butadiene-Styrene (SBS) Triblock Copolymer Proton Exchange Membranes†

A new synthetic method that generates a middle block sulfonated SEBS proton exchange membrane through partial hydrogenation of polystyrene-b-polybutadiene-b-polystyrene and subsequent thiol-ene click reaction and oxidation. By switching the sulfonation...
