TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Process: The process further comprises a procedure of essentially repeating step (i) and step (ii) that includes (a) subjecting the NGP material to a supercritical fluid at a second temperature and a second pressure for a second period of time in a pressure vessel and then (b) rapidly depressurizing the fluid at a fluid release rate sufficient for effecting further exfoliation of the NGP material. The second temperature differs from the first temperature and the second pressure differs from the first pressure. The process further comprises: mixing the nano graphene material with a thermosetting resin; and imparting a chemical group to the nano graphene material in the pressure vessel. Preferred Components: The NGP material, when formed into a thin film with a thickness no greater than 100 nm, exhibits an electrical conductivity of at least 100 S/cm, preferably at least 1000 S/cm. The nano graphene material has a specific surface area of approximately 300-2600 m2/g. The NGP material comprises single-layer graphene. The graphitic material is natural graphite, artificial graphite, graphite oxide, graphite fluoride, graphite fiber, carbon fiber, carbon nano-fiber, carbon nanotube, mesophase carbon micro-bead, soft carbon and/or hard carbon.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The supercritical fluid comprises: a fluid comprising carbon dioxide, water, water oxidation, hydrogen peroxide, methane, ethane, ethylene, ozone and/or sulfonic group; a surfactant or dispersing agent dissolved in it; a reactive chemical group; a coating agent dissolved in it; and a curing agent dissolved in it.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The coating agent comprises a monomer, a prepolymer or oligomer, a polymer, a resin and/or a curing agent. EXAMPLE - A natural graphite sample ( approximately 5 g) was placed in a vessel. The vessel was in fluid communication with high-pressure carbon dioxide. High pressure carbon dioxide was introduced into the vessel and maintained at approximately 1100 psig (7.58 MPa). Subsequently, the vessel was heated to about 70 degrees C and maintained for about 3 hours, allowing carbon dioxide to diffuse into inter-graphene spaces. Then, the vessel was immediately depressurized catastrophically at a rate of 3 milliliters per second to give graphene layers containing pristine nano graphene platelets with an average thickness of below 10 nm.
