| 英文摘要 | a series of disulfonated poly(sulfide sulfone)s (spssf)s copolymers are synthesized via direct aromatic nucleophilic substitution polycondensation of 4,4'-dichlorodiphenylsulfone (dcdps), 3,3'-disulfonate4,4'-dichlorodiphenylsulfone (sdcdps) and 4,4'-thiobisbenzenethiol at various molar ratios. tough and flexible membranes with 30 mol% (spssf30) to 50 mol% (spssf50) sdcdps monomers are obtained by casting from dmac solution. their physicochemical properties including thermal properties, mechanical properties, water uptake, swelling ratio and oxidative stability are fully investigated. and the fuel cell performance of spssf membranes at different temperature and relative humidity is evaluated comprehensively for the first time. it is found that the spssf40 membrane exhibited low dimensional change in the temperature range of 20-100 degrees c, good mechanical properties, high oxidative stability and comparable fuel cell performance to nafion 212 membrane. besides, the h-2 crossover density of the spssf40 membrane is only 50% of that of naflon 212 membrane. consequently, spssf40 membranes prove to be promising candidates as new polymeric electrolyte materials for proton exchange membrane (pem) fuel cells operated at medium temperatures.
