| 中文摘要 | a cross-linked network is obtained by an end-group cross-linkable pbi (e-pbi) and 4,4'-diglycidyl (3,3',5,5'-tetramethylbiphenyl) epoxy resin (tmbp). the formation of the network is proved by ft-ir and gel fraction test. then, high temperature proton exchange membranes are constructed by incorporating the cross-linked network into poly(2,2'-(1,3-phenylene)-5,5'-bibenzimidazole) (m-pbi). the influences of the end-group cross-linked network on the properties of membranes are studied, such as, phosphonate acid doping ability, thermal stability, mechanical property, oxidative stability and proton conductivity. the e-pbi/tmbp in the membranes contributes to the improvement of acid doping ability, proton conductivity, mechanical properties and oxidative stabilities. the blend membranes with 20-90 wt% e-pbi/tmbp show higher proton conductivity than pristine pbi at 120 degrees c-180 degrees c. these results indicate that the end-group cross-linked blend membranes are promising materials as high temperature proton exchange membranes.
