Crosslinked ion exchange resin composite membranes were prepared by casting sulfonated polystyrene(SPS) solution with suspended ion exchange resin(crosslinked SPS) and crosslinker (trimethylolpropane ethoxylate triacrylate (TMPETA)) follow by gamma-ray irradiation. The physicochemical properties of the composite membranes were evaluated by measuring gel-fraction, ion exchange capacity, water-uptake and dimensional stability. We confirmed that the introduction of ion exchange resin and radiation crosslinking in the membranes improved the water uptake, dimensional stability and permselectivity.
