Synthesis and Characterization ofSulfonated Poly(ether sulfone)sfor Proton Exchange Membrane Fuel cell |
| 초록 |
poly(ether sulfone)s with bisphenol-TP and bisphenol-A ＜PBTP-BPA＞, or bisphenol -AF ＜PBTP-BAF＞ were prepared with Bisphenol-TP ＜4,4-dihydroxy tetraphenyl methane＞, 4-Fluorophenyl sulfone and bisphenol-A or bisphenol-AF ＜4,4-(hexafluoroisopropylidene)diphenol＞ using potassium carbonate in sulfolane ＜tetramethylene sulfone＞ at 210 ℃. Sulfonated PBTP-BPA and PBTP-BAF were obtained by reaction of chlorosulfuric acid with copolymers. A series of copolymers were studied by 1H-NMR spectroscopy, differential scanning calorimeter (DSC), and thermo gravimetric analysis (TGA). Sorption experiments were conducted to observe the interaction of sulfonated polymers with water and methanol. |
