Patent ID: 8114375

Claim:
A process for producing a dispersible nano graphene or graphene oxide platelet material, said process comprising: (a) preparing a graphite intercalation compound (GIC) or graphite oxide (GO) from a laminar graphite material selected from the group consisting of artificial graphite, graphite fluoride, graphite fiber, carbon fiber, carbon nano-fiber, carbon nano-tube, mesophase carbon micro-bead (MCMB) or carbonaceous micro-sphere (CMS), soft carbon, hard carbon, and combinations thereof; (b) exposing said GIC or GO to a first temperature for a first period of time to obtain exfoliated graphite; and (c) exposing said exfoliated graphite to a second temperature in a protective atmosphere for a second period of time to obtain said dispersible nano graphene platelet material with an oxygen content no greater than 25% by weight.
