The sulfonated PVDF-g-4-vinylbenzene sulfonate membranes(SPVS) were synthesized by graft polymerization. The structure of membranes was investigated by FT-IR, Raman and X-ray Photoelectron Spectroscopy (XPS). The water content, ion exchange capacity, electrical resistance, ion conductivity were measured. The maximum values of IEC and ion conductivity were 1.2 meq/g and 0.0097 S/cm, respectively. The minimum values of water content and electrical resistance were 15.5% and 1.31 Ω • cm2, respectively. |
