| 中文摘要 | a series of novel multiblock copolymers based on sulfonated copolyimides were developed and evaluated for use as proton exchange membranes (pems). in these multiblock copolyimides, the hydrophilic blocks were composed of the sulfonated dianhydride and the sulfonated diamine, with sulfonic acid groups on every aromatic ring (i.e., fully sulfonated). this molecular design was implemented to effectively enhance the proton conductivity. the properties of the multiblock copolyimides with varying iec values or block lengths were investigated to obtain a better understanding of the relationship between molecular structure and properties of proton exchange membranes. the water uptake and proton conductivity were found to be highly dependent upon their structure. the block copolymers displayed significantly higher proton conductivities, especially at low relative humidity than the random copolymers with a similar iec. |
