제목 Synthesis and Characterization of Sulfonated Poly(Phenylene Sulfide Sulfone Nitrile) for Direct Methanol Fule Cell Applications
초록 High molecular weight sulfonated poly(phenylene sulfide sulfone nitrile) (SPSSN) with various degrees of sulfonation (DS) were prepared by polycondensation of monomers in N-methyl-2-pyrrolidone. The chemical structures of SPSSNs were confirmed by FT-IR and 1H NMR spectroscopy. SPSSN membranes with DS lower than 50% show relatively higher oxidative stability than any other sulfonated poly(arylene ether)s. Furthermore, SPSSN membranes exhibit improved methanol barrier property and proton conductivity as compared with Nafion membrane. Consequently, the membrane-electrode assemblies based on SPSSN membranes show excellent electrochemical DMFC performances at high temperature of 90 oC.
