Abstract

Abstract A series of polyphosphazene-based copolymers containing alkylsulfonated side chains were prepared and made into the corresponding membranes by the reaction with 2,6-bis(hydroxymethyl)-4-methylphenol (BHMP) as the cross-linking reagent. All the cross-linked membranes showed lower water uptake and dimensional swelling. They displayed significant methanol resistance ranging from 1.35 to 7.18 × 10^-7 cm²/s and high oxidative stabilities. The individual membrane PFMPP₁-r-PFSPP₉ showed good proton conductivity (0.14 S/cm) under fully hydrated conditions at 80 °C.
