Studies on Preparation and Properties of PVDF-PSSA Membrane

Abstract:

A proton exchange membrane, poly (vinylidene fluoride)(PVDF) blended polystyrene sulfonated acid(PSSA) was prepared by Blend polymerization method. Mechanical properties of membranes were investigated by the multi-functional material experiment machine.The influences of the content of the styrene on the proton conductivity and methanol permeability of the membranes were studied by the impedance analyzer and gas chromatography instrument. The results showed that Polystyrene is easily blended into PVDF and mechanical properties were improved, with increasing of the content of styrene, the proton conductivity of PVDF-PSSA membranes was increased, and arrived at maximum as the styrene content was 20%, correspondingly, methanol permeability became large gradually.
