Composite membrane containing highly sulfonated polymer grafted graphene oxide for proton exchange membrane fuel cells (PEMFCs) application |
| 초록 |
For proton exchange membrane fuel cells application, sulfonated poly(arylene ether sulfone) (SPAES)-based composite membranes containing highly sulfonated polymer grafted graphene oxide (SATS-GO) were prepared. SATS-GO was obtained by the reaction between sulfonated poly(arylene thioether sulfone) (SATS) and graphene oxide (GO) in mild reaction condition. Pristine GO composite membrane was also fabricated as a control group for the study of the effect of SATS-GO on composite membrane. SATS-GO composite membranes exhibited improved physicochemical properties such as mechanical properties and oxidative stability and proton conductivity compared to pristine SPAES membrane. It was found that SPAES/SATS-GO-2.0 composite membrane expecially exhibited the highest proton conductivity values of 4.63 mS cm-1 at 80 °C and 40% RH. |
