TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Process: The step of preparing a graphite intercalation compound or graphite oxide comprises subjecting the laminar graphite material to an acid and/or an oxidizer comprising sulfuric acid, nitric acid, carboxylic acid, sodium or potassium nitrate, potassium permanganate, sodium or potassium chlorate and/or hydrogen peroxide. The process further comprises a step of contacting the nano graphene platelet material formed in the step of exposing the exfoliated graphite, with a reactant such that a functional group is added to a surface or edge of the nano graphene platelet material. Preferred Components: The protective atmosphere comprises an inert gas, nitrogen and/or hydrogen, or vacuum. The second temperature is higher than the first temperature. The oxygen content is below 20 wt.%, preferably 5-20 wt.%. The first temperature is approximately 200-1500 degrees C, preferably approximately 800-1300 degrees C. The second temperature is approximately 800-1500 degrees C, preferably at least 1000 degrees C, 1100 degrees C or 1200 degrees C, at the second period of time of at least 10 minutes, at least 5 minutes or at least 2 minutes respectively. The dispersible nano graphene platelet material, when formed into a thin film with a thickness not greater than 100 nm, exhibits an electrical conductivity of at least 10 S/cm, preferably at least 600 S/cm. The laminar graphite material is also natural graphite and/or graphite oxide. The nano graphene material has a specific surface area of approximately 300-2600 m2/g. The nano graphene platelet material comprises single-layer graphene.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The functional group is alkyl or aryl silane, alkyl, aralkyl, hydroxyl, carboxyl, amine, sulfonate, aldehydic, quinoidal and/or fluorocarbon. EXAMPLE - Mesophase carbon microbead (MCMB) 2528 (10 g) were intercalated with an acid solution (sulfuric acid, nitric acid and potassium permanganate at a ratio of 4:1:0.05) for 24 hours. Upon completion of the reaction, the mixture was poured into deionized water and filtered. The intercalated MCMBs were repeatedly washed in a 5% solution of hydrochloric acid to remove most of the sulfate ions. The sample was then washed repeatedly with deionized water until the pH of the filtrate was neutral. The slurry was spray-dried and stored in a vacuum oven at 60 degrees C for 24 hours. The dried powder sample was placed in a quartz tube and inserted into a horizontal tube furnace pre-set at 600 degrees C for 30 seconds to give exfoliated oxidized MCMB platelets. Approximately one half of the exfoliated MCMB sample was subjected to de-oxygenation treatment at 1250 degrees C for 15 minutes in an argon environment to give de-oxygenated sample. A small quantity of each sample was mixed with water and ultra-sonicated at a 60 W power for 10 minutes to give a suspension and thin films were prepared from each suspension by dip coating. The conductivity of the film prepared from exfoliated oxidized MCMB platelets was approximately 1.8x 102 S/cm and that of de-oxygenated sample was 67 S/cm and both types of platelets were well-dispersed in water.
