We synthesized a non-fluorine resin poly (arylene thioether sulfone) and compared to Nafion. Directly copolymerized wholly aromatic sulfonated poly (arylene thioether sulfone) copolymers derived from 3,3-disulfonate-4,4’-dichlorodiphenyl sulfone, 4,4’-dichlorodiphenylsulfone, and 4,4’-thiobisbenzenethiol in the presence of potassium carbonate were investigated. 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, ion conductivity, permeability. |
