Abstract

π-π stacking between GO and benzene sulfonic acid (BS), naphthalene sulfonic acid (NS), pyrene sulfonic acid (PS), and naphthalene disulfonic acid (ND) results in the formation of respective GO-BS, GO-NS, GO-PS and GO-ND hybrid materials. The proton conductivities of these materials follow the trend as GO-NS>GO-BS>GO-PS>GO>GO-ND. GO-NS, possessing the highest interlayer distance, exhibits the optimum proton conductivity. Evidently, GO-sulfonic acid hybrids reveal excellent superionic conductivity.
