SULFONATED POLY(ARYLENE SULFONE), CROSSLINKED MATERIAL THEREOF, CLAY NANO-COMPOSITE USING THE SAME, AND FUEL CELL USING THE SAME

摘要

PURPOSE: Sulfonated poly(arylene sulfone), a crosslinked material thereof, and a clay nano-composite are provided to improve mechanical properties and ion conductivity by improving brittleness and solvent resistance and to obtain an electrolyte membrane reducing crossover of fuel. CONSTITUTION: Sulfonated poly(arylene sulfone) includes a first repeating unit which is marked as a chemical formula 1a, a second repeating unit which is marked as a chemical formula 1b, a third repeating unit which is marked as a chemical formula 1c, and a fourth repeating unit which is marked as a chemical formula 1d. In the chemical formulas, R1 is an alkyl group with C1-C10, an alkyenyl group with C2-C10, or a nitro group and p is an integer of 0-4.
