A novel terminally crosslinked block SPES-b membrane was prepared using an azide-assisted thermal curing of sulfonated multiblock poly(arylene ether sulfone). The membrane morphologies and conductivities were investigated as a function of temperature. The crosslinked block SPES-b membrane showed higher proton conductivities than Nafion® both at 20 °C (0.09 S/cm) and 100 °C (0.77 S/cm). High temperatures induced significant conduction enhancements and morphological changes for SPES-b.
