Nanografite dispersion (concentration of nanographite to 1 mg/ml) - is the dispersion of nanographite in water of dark gray color. Particles of nanographite have a metallic luster. As a stabilizer for aqueous dispersions, the addition of surfactants is possible. The precursor of nanografite is natural graphite (purity 99.99%). The content of low-layer graphenes in the nanographite dispersion is 1-3%.

* Between graphite and its structural element - graphene there is an "intermediate state", which is commonly called nanographite.
