The graphite oxide (GO) sample has been generated by the well-known Hummers’ method, that is a chemical reaction based on the oxidation of graphite flakes by a solution of potassium permanganate (KMnO4) and sodium nitrate (NaNO3) in absolute sulfuric acid (oleum, H2SO4). Graphite oxide is a very useful chemical compound since it is the precursor of single-layer graphene; indeed, it is an unstable compound that spontaneously decomposes with time or can be very easily reduced by heating or by treatment with a mild chemical reluctant (e.g., ascorbic acid). The obtained thermally/chemically reduced graphene oxide has a number of structural defects due to the presence of residual oxygen-containing groups (epoxies) and holes in the graphene plane structure. While GO is a non-electrically conductive nanostructure because electron conjugation is interrupt for the presence of a large amount of oxygen-containing groups (hydroxyls, carboxylic groups, epoxies, etc.), the thermally/chemically reduced graphene oxide is a good electrical conductor, that is useful for different technological applications [1].
