Sulfonated Poly

A new series of hydrophobic-hydrophilic multiblock sulfonated poly (arylene ether ketone)-b-poly (arylene ether ketone) copolymers were successfully synthesized and evaluated for use as proton exchange membranes (PEMs). The membrane properties of block copolymers including ion exchange capacities (IECs), water uptake and proton conductivities were characterized for the multiblock copolymers and compared with random sulfonated poly (arylene ether) s and other multiblock copolymer membranes at similar ion exchange capacity value. This series of multiblock copolymers showed moderate conductivities up to 0.063 S/cm at 80 °C with very low water uptake of 19%. Therefore, they are considered to be promising PEM materials for fuel cells.

Abstract Sulfonated poly(arylene thioether ketone ketone sulfone)s (SPATKKS) were synthesized by nucleophilic polycondensation of various amounts of 1,3- bis(4-fluorobenzoyl)benzene, 1,3-bis(3-sodium sulfonate-4-fluorobenzoyl)benzene, and 4,4’-dichlorodiphenylsulfone with 4,4’-thiobisbenzenethiol. Sulfonated poly- (arylene ether ketone ketone sulfone)s were also prepared in order to compare their oxidation resistance to peroxides with that of SPATKKS. SPATKKS show high oxidation resistance to peroxides. The resulting ionomers with moderate ion exchange capacity present excellent thermal stability (the 5% weight loss temperature is about 500°C) and low water uptake and swelling ratio until 85°C. The materials hold promise for application as proton exchange membranes in fuel cells.
