Sulfonated hydrocarbon based composite membrane having sulfonated polytriazole grafted graphene oxide for proton exchange membrane fuel cell applications |
| 초록 |
Sulfonated poly(arylene ether sulfone)(SPAES) composite membranes were prepared using thermally treated graphene oxide (GO) and sulfonated polytriazole grafted graphene oxide(SPTA-GO) as fillers for proton exchange membrane fuel cell(PEMFC) applications. SPTA-GO was prepared through an click reaction using ethynylterminated sulfonated polytriazole and azide functionalized GO(N3-GO). In particular the SPAES/SPTA-GO composite membrane exhibited improved proton conductivity than SPAES/GO composite membrane due to the SPTA moiety attached to GO had both sulfonic acid and triazole groups that could form additional proton conduction channels. Furthermore, the cell performance of the membrane electrode assembly(MEA) employing the SPEAS composite membrane with SPTA-GO was found to be better than that employing Nafion 212 under various operationg conditions. |
