Sulfonated graphene oxide/ sulfonated poly(arylene ether sulfone) composite membrane with high selectivity for unitized regenerative fuel cells |
| 초록 |
Composite membranes based on sulfonatedgraphene oxide (sGO)/sulfonatedpoly(arylene ether sulfone) (sPAES) were fabricated for the unitized regenerative fuel cells (URFCs). The sulfonation of and poly(arylene ether sulfone) increased the number of sulfonic acid functional groups (SO3H) in the membrane, which fairly increased the ionic conductivity of composite membrane. The gas permeability of composite membrane decreased due to the introduction of the sGO as a barrier material. Therefore, it was found that the composite membrane based on sGO/sPAES exhibited the high selectivity (conductivity/permeability) and can be useful for URFCs. |
