| 中文摘要 | a series of novel oxidation and water stable sulfonated polyimides (spis) were synthesized from 4,4'-binaphthyl-1,1',8,8'-tetracarboxylic dianhydride (btda), and wholly aromatic diamine 2,2'-bis(3-sulfobenzoyl) benzidine (2,2'-bsbb) for proton exchange membrane fuel cells. these polyimides could be cast into flexible and tough membranes from m-cresol solutions. the copolymer membranes exhibited excellent oxidative stability and mechanical properties due to their fully aromatic structure extending through the backbone and pendant groups. moreover, all btda-based spi membranes exhibited much better water stability than those based on the conventional 1,4,5,8-naphthalenecarboxylic dianhydride. the improved water stability of btda-based polyimides was attributed to its unique binaphthalimide structure. the spi membranes with ion exchange capacity (iec) of 1.36-1.90 mequiv g(-1) had proton conductivity in the range of 0.41 x 10(-1) to 1. 12 x 10(-1) s cm(-1) at 20 degrees c. the membrane with iec value of 1.90 mequiv g(-1) displayed reasonably higher proton conductivity than nafion((r)) 117 (0.9 x 10(-1) s cm(-1)) under the same test condition and the high conductivity of 0.184 s cm(-1) was obtained at 80 degrees c. microscopic analyses revealed that well-dispersed hydrophilic domains contribute to better proton conducting properties. these results showed that the synthesized materials might have the potential to be applied as the proton exchange membranes for pemfcs. |
