Synthesis and characterization of polyphenylene containing tetraphenylethylene moiety by nickel catalyzed polymerization for PEM application |
| 초록 |
The synthesis of polyphenylenes containing tetraphenylethylene moiety, their functionalization with sulfonic acid groups, and the measurement of apposite parameters for PEMs are described. The polymers were prepared by Ni-catalyzed carbon-carbon coupling polymerization of dichlorotetraphenylethylene and 2,5-dichlorobenzophenone. These polymers have all carbon-carbon linkages without any ether linkage on polymer backbone, which were not attacked by nucleophiles, and the twisted structure provided good solubility in aprotic polar solvent. The sulfonic acid groups were introduced by sulfonation reaction with concentrated sulfuric acid. All these membranes were prepared from dimethylacetamide (DMAc) polymer solution. The membranes were studied by ion exchange capacity (IEC), water uptake, proton conductivity, Fenton test, and single cell performance. |
