End-group cross-linked membranes based on thiolate terminated sulfonated poly(arylene ether sulfone) and vinyl functionalized graphene oxide for fuel cell application |
| 초록 |
Vinyl functionalized graphene oxide (VGO) composite membranes are fabricated using thiolate terminated sulfonated poly(arylene ether sulfone) (SPAES) with very high degree of sulfonation (DS=90). Since end group cross-linked network is developed between VGO and SPAES90 through the thiol-Michael addition reaction, free-standing cross-linked cSPAES90 membrane could be obtained although pristine SPAES90 membrane is water soluble. The cSPAES90 membranes are found to have excellent physiochemical properties with high proton conductivity. For example, cSPAES90 membrane containing 1 wt% VGO shows good dimensional stablity than SPAES membrane with DS of 70 mol% and the proton conductivities are larger than those of the Nafion 211 under 40%-90% relative humidity at 80oC |
