| Pure Graphene Platelets. These are produced in three grades: Grade H, which are platelets with ~15 nanometer thickness (50-80 m2/g) and mean diameters of 5, 15, and 25 microns. Grade M, which are platelets with ~7 nanometer thickness (120-150 m2/g)and mean diameters of 5, 15, and 25 microns. Grade C, which are platelets with thickness less than 2 nanometer, overall diameter less than 2 microns, and are available in surface areas of 150, 300, 500, and 750 m2/g. These materials are furnished as dry black powders (granules) or can be obtained in a dispersion. When used as a filler for polymers, a loading between 3 and 10% is suggested. |
