| Abstract: | A new sulfonated dendrimer with an arylene ether sulfone backbone has been synthesized, fully characterized, and blended with PBIOO® to prepare acid‐base proton‐conducting membranes under different conditions and with different composition ratios. Water‐soluble sulfonated hyperbranched polyglycerols of different molecular weights were also used as the acidic components. Membrane properties such as ion‐exchange capacity, water uptake, thermal stability, proton conductivity, and morphology have been studied and discussed. The nature of the acidic component and the morphology of the membranes had a marked influence on the final properties. © 2015 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.
