摘要：
Sulfonated phenolphthalein poly(ether sulfone) (SPES-C) with various sulfonation degree were synthesized by reaction of PES-C with sulfonic acid as sulfonating agent and solvent. Their proton conductivity and methanol permeability as a function of the degree of sulfonation were investigated. For 70.21 % degree of sulfonation, proton conductivity was 3.45 x 10(-2) S/cm at 100degreesC which is closed to or superior to that of Nafion(R) 115 membrane at the same conditions (4.19 x 10(-2) S/cm). Methanol permeability of SPES-C was considerable smaller than that of Nafion(R) 115 membrane. Because of their high conductivity and low methanol permeability, SPES-C membranes appear to be excellent candidate for use in DMFC applications.
