Synthesis and characterization of sulfonated DOPO base poly(arylene ether sulfone) multiblock copolymers for fuel cell application |
| 초록 |
Sulfonated multiblock poly(arylene ether sulfone) copolymers containing DOPO group were prepared from the precursors of hydrophilic and hydrophobic block oligomers. The hydrophobic oligomer was prepared by 4,4’-dihydroxydiphenylsulfone and 4,4’-difluorodiphenylsulfone. And the hydrophilic oligomer prepared by DOPO and 4,4’-difluorodiphenylsulfone. Post-sulfonation process wes applied to add sulfonic acid on DOPO unit by using conc. Sulfuric acid. A series of membranes were studied by 1H-NMR spectroscopy, FT-IR, TGA, and DSC etc. The IEC and Proton conductivity of S-DOPDs were evaluated with increase of DS. |
