Production of graphene powder involves heat-treating graphitizable polymer film, forming heat-treated film having turbostratic graphitic structure, shearing heat-treated film, and forming particulate having thickness in specified range.

SRIVASTAVA I

Making graphene oxide or flakes, comprises placing graphite into water containing oxidizing agent, mechanically exfoliating graphite into graphene flakes, and separating graphene flakes from water.

BLAIR R

Preparation of graphene suspension used as additive for supercapacitor electrode, involves preparing graphene flakes, preparing polar or nonpolar fluid, and suspending graphene flakes in fluid by mixing until suspension is uniform.
