Abstract Poly (styrenesuflonic) acid (PSSA) and poly (vinylidene fluoride) (PVDF) composite membranes have been prepared by free radical polymerization. By reading the relationship of the reaction–time and the characteristics of microstructural, electrochemistry and physical properties of PVDF/PSSA Composite Membranes by SEM, EDX, EIS and TG, it is found that both the water content of PVDF/PSSA membrane and proton conductivity did increase if the hot–pressing time was extended. When the hot–pressing reactive time approached the optimum values at 8 hour, the water content reached 4.4% at the room temperature, the proton conductivity reached the maximum (0.375 S/cm) and the resisting strength reached to 32.1 MPa, which shows that the conductivity of the SIPN composite membrane can be improved clearly while holding the better mechanical and thermo property by free radical polymerization.
