Interestingly, proper solvation of the potassium cations was beneficial to the covalent functionalization, while excessive solvation led to destabilization and floccula-tion, with decreased reactivity of graphenide. The results were confirmed by scanning Raman spectroscopy (SRS) and x-ray photoelectron spectroscopy (XPS).engAtribución 3.0https://creativecommons.org/licenses/by/3.0/GrapheneGraphenideReactivitySolvationjournal articleopen access10.1088/2053-1583/aafd9b
