| 英文摘要 | A series of sulfonated poly(ether ether ketone) (SPEEK) and graphene oxide (GO) blend membranes were prepared with various mixing mass ratios. The water uptake, ion exchange capacity, proton conductivity, vanadium ion permeability, mechanical properties and chemical stability were measured. The blend membranes were characterized by FTIR, SEM and TG. The blend membranes exhibit higher water uptake and ion exchange capacity and lower vanadium ion permeability than Nafion115 membranes, the ion exchange capacity decreases with the increase of GO content. The VO2+ permeability of the blend membranes decreased, while mechanical properties increased with increasing GO content. Random embedding of GO in the membranes can block the transport of vanadium ions effectively, resulting in vanadium ion permeability of the blend membranes decreased obviously. In VRB single cell test, the blend membranes showed higher energy efficiency (EE) compared with Nafion115 membrane, the EE of S/GO-2 (GO, 2 wt%) blend membrane was 80% which increased by 9% compared to that with Nafion115. The S/GO blend membranes showed stable performance up to 100 cycles test. The experimental results indicate that the S/GO blend membranes show favorable development prospects for VRB. |
