Graphene Oxide (GO) is a product of deep oxidation of graphite, has the simplest formula C2OH and contains a large number of oxygen-containing functional groups. The Graphene Oxide is a hydrophilic material and therefore is able to form colloidal solutions in water, dimethylformamide, N-methyl-pyrrolidone, aqueous solutions of ethanol and other polar solvents.
Reduced Graphene Oxide (RGO) is a product of the reduction of GO under thermal exposure (heating or microwave irradiation) or chemical reduction. The Reduced Graphene Oxide has a large specific surface and high conductive characteristics in contrast to GO. The Reduced Graphene Oxide is a black powder with a low density (~0.7 g/100 ccm) and contains more than 96 weight % of carbon.
