S-DDM was prepared by the direct sulfonation of DDM monomer. The degree of sulfonation of the sulfonated copolyimide was varied by using various molar concentrations of S-DDM. The sulfonated copolyimide with the highest degree of sulfonation possessed the proton conductivity of 0.0032 S.cm-1 in a wet state. The highest methanol permeability of the sulfonated copolyimide was 2.75 × 10-8 cm2.s-1 which is ~425 times lower than that of the Nafion 117. The highest membrane selectivity belonged to the membrane with 34% degree of sulfonation with the value of 1.65 × 106 s.S.cm-3 which is three orders of magnitude higher than the commercial Nafion 117.","descriptionType":"Abstract"}],"geoLocations":[],"fundingReferences":[],"xml":"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","url":"https://scielo.figshare.com/articles/Proton_Exchange_Membrane_Based_on_Sulfonated_Poly_Aromatic_Imide-Co-Aliphatic_Imide_for_Direct_Methanol_Fuel_Cell/5719237/1","contentUrl":null,"metadataVersion":2,"schemaVersion":"http://datacite.org/schema/kernel-4","source":"mds","isActive":true,"state":"find
