제목 Synthesis and Characterization of Isatin biphenylene block copolymer with Sulfonyl Imide via Super Acid Catalyzed Polymerization for PEMFC Applications
초록 Over the past few decades, many researchers have been developing hydrocarbon polymers which have better characteristics than Nafion. Our research group has made an effort to improve the membranes properties In this study, carbon-carboned polymer was synthesized by using superacid catalyst. Poly(isatin biphenylene)s were prepared by super acid catalyzed polyhydroxyalkylation Sulfonyl imide monomer was prepared from chlorosulfuric acid and fluorosulfonylisocyanate. Sulfonyl imide group have higher acidity than sulfonic acid group. Therefore, these membranes expect to improve performance of proton conductivity, water uptake, and dimensional stability. The structure of the synthesized polymer was investigated by 1H NMR spectroscopy. These membranes will be studied by proton conductivity, water uptake, dimensional stability, and ion exchange capacity (IEC). Surface morphologies will also be assessed by atomic force microscope (AFM).
