Producing pristine graphene nanoplatelets used in e.g. paints, comprises expanding flakes of intercalated graphite, dispersing expanded graphite in water in absence of surfactant and subjecting to exfoliation and size reduction treatment.

CESAREO G, PARRINI M R, RIZZI L G

Preparing graphene sheet by performing electrochemical reduction of graphite and alkali metal under condition of non-aqueous electrolyte, which is used as intercalation agent and short circuit environment.

SHI P, XIANG H

Producing flake graphene by direct exfoliation of graphite involves preparing an aqueous suspension of graphite with addition of surface active agents or surfactants, freezing the suspension, and drying the suspension.
