Process for In-situ Functionalization of Graphene
28 Jul 22
A process for in situ functionalization of graphene including placing a graphitic precursor in an exfoliation cannister with exfoliation media; creating an inert atmosphere in the exfoliation cannister; exfoliating the graphitic precursor to form graphene having carboxyl moieties; and reacting the carboxyl moieties in the exfoliation cannister under conditions, such as a temperature of between 260 and 500° C., and in the presence of a substance to chemically reduce or react the carboxyl moieties during the exfoliating to produce hydrophobic graphene.
