In order to accomplish RIGP of SSA, we used acceleration vinyl monomers such as styrene (St) and acrylic acid (AAc) for preparing ion-exchange membrane. As results, we successfully prepared the poly(St-co-SSA)-g-PVDF and poly(AAc-co-SSA)-g-PVDF membrane by RIGP method. We also characterized for the prepared membranes as follows.The ion-exchange group content of poly(St-co-SSA) and poly(AAc-co-SSA) were 9.65 and 26.3 meq/g by titration method, respectively. The proton conductivities were 0.0018 S/cm and 0.0019 S/cm at room temperature by impedance analysis, for poly(St-co-SSA)-g-PVDF and poly(AAc-co-SSA)-g-PVDF, respectively.From these results, the membranes prepared by RIGP can be used in methanol fuel cell separator. |
