The results of the study of electrochemical dispersion of flake graphite in sulfuric acid were presented. It was shown that the highest dispersion efficiency was achieved while using large fractions of graphite with a particle size being more than 200 microns. The formation of the multilayer graphene oxide structures with the thickness of 0.1–1.0 microns and lateral dimensions up to 100 microns during anodic oxidation of graphite was established. The graphene structures were identified by the x-ray phase analysis and IR-Fourier spectroscopy. The possibility of obtaining base-free films from multilayer graphene oxide particles without the participation of a binder was shown, with the prospect of using them to create the flexible electrodes for supercapacitors and chemical current sources.
