Pore Filled Ion-Conducting Materials Based on Track-Etched Membranes and Sulfonated Polystyrene

Abstract Synthesis of proton-conducting materials based on track-etched membranes from polyvinylidene fluoride and sulfonated cross-linked polystyrene is described. The synthesis has been carried out by filling the pores original or gamma-irradiated membrane copolymerization styrene/divinylbenzene followed sulfonation with chlorosulfonic acid. resulting have studied scanning electron microscopy ATR IR spectroscopy. Membrane ionic conductivity, hydrogen gas permeability, ion-exchange capacity, water absorption were measured. conductivity at 30°C reaches 51.7 mS/cm, which almost three times higher than for Nafion®212 membranes; however, permeability obtained also increases simultaneously.
