Abstract
A method for preparing aqueous or organic suspensions of fully exfoliated nanocarbon materials includes a) dissolving a nanocarbon intercalation compound in an aprotic organic solvent (A) or a mixture (A') of aprotic organic solvents under inert atmosphere; b) re-oxidation to revert the reduced nanocarbon material to its neutral state; and c) mixing the organic suspension of neutral nanocarbon obtained in step b) with a suitable amount of degassed water, degassed ionic aqueous solution, degassed organic solvent (B), degassed mixture (B′) of organic solvents, or degassed mixture of (B) or (B′) with water or an aqueous ionic solution; wherein solvent (A) or solvent mixture (A′) is fully or partially water-miscible or fully or partially miscible with solvent (B) or solvent mixture (B′); thereby leading to an air-metastable aqueous or organic suspension of nanocarbon material.
