Dispersion of graphene oxide (1–4 mg/ml) – concentrated graphene oxide dark brown dispersion in water. Based material dispersion - graphene oxide. Below is a specification of graphene oxide powder

Graphene oxide - is a dark gray fine-dispersed powder. Under the action of ultrasound in polar and hydrophilic solvents forms stable dispersions (water, alcohols, etc.). Under the action of ultrasound in nonpolar hydrophobic solvents forms unstable dispersions (hexane). Keep the powder at room temperature in a closed weighing bottle.
