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.
