The polyperfluorinated sulfonic acid membranes are state-of-the-art PEMs, used for both hydrogen and methanol fuel cells. We synthesized a non-fluorine resin poly (arylene thioether sulfone) and compared to Nafion. The composition and incorporation of the sulfonated repeat unit into the copolymers were confirmed by ¹H-NMR and Fourier transform infrared Spectroscopy. The memebranes were prepared from the casting and the degree of sulfonation were controlled by using various the ratio of 3,3-disulfonate-4,4’-dichlorodiphenyl sulfone. Detailed results will be discuss additional characteristics of these copolymers using ion exchange capacity, water uptake, proton conductivity, permeability. This oxidated polymers with extremely electron-deficient aromatics shows very high thermal, thermooxidative and hydrolytic stabilities, low solubilities, and reduced swelling in water. |
