- Abstract:
- Herein, graphene oxide (GO) was synthesized through the improved Hummers method, and then phosphoric acid was intercalated into the interlayers to fabricate phosphoric acid intercalated graphene oxide (PGO). GO and PGO were incorporated into sulfonated poly(ether ether ketone) (SPEEK) matrix to prepare composite membranes through solution casting method. The physicochemical property and proton conduction property of composite membranes were investigated in detail. The results suggested that all the membranes were thermally stable up to 290℃. Under anhydrous condition, the PGO formed highly efficient transfer channels in composite membrane, which significantly enhanced the proton conduction property of membrane. Particularly, the proton conductivity of SPEEK/PGO-50 reached 7.92 mS• cm-1 at 150℃, which was 5.7 times of that of SPEEK control membrane and 4.6 times of that of SPEEK/GO.
