Abstract
New series of polymer composite membranes were prepared from sulfonated polystyrene-<i>block</i>-poly(ethylene-ran-butylene)-<i>block</i>-polystyrene (S-PSEBS) and copper oxide loaded in graphitic carbon nitride (CuO@N-C) embedded with an ionic liquid, 2,4,6-triphenylpyrylium tetrafluoroborate. The structural and physicochemical properties of the composite membranes were studied in detail. Electrolyte membrane loaded with 8.0 wt% of CuO@N-C exhibited the maximum ion-exchange capacity of 3.1 meq. g<sup>-1</sup>, whereas that of the pristine membrane was restricted to 1.8 meq. g<sup>-1</sup>. From the TGA profile of the composite membrane, it was found to exhibit adequate thermal stability to be employed as electrolyte in fuel cells. Proton conductivity of the composite membranes was found to be in the range between 0.0179 S cm<sup>-1</sup> and 0.0229 S cm<sup>-1</sup>. Indeed, the substantial results achieved with the S-PSEBS/CuO@N-C composite membranes were indicative of the notable features of the membranes for use in fuel cells.
