Graphite oxide - a product of the deep oxidation of graphite, it has a simple formula C2OOH and contains a large amount of oxygen-containing functional groups. Graphite Oxide - a hydrophilic material, it is capable of forming colloidal solutions in water, dimethylformamide, N-metilpirroliidone, ethanol and aqueous solutions of other polar solvents, where it exfoliated thin (up to one carbon layer) sheets of graphene oxide (GO).

Application of graphene oxide Properties

•Solar Ceils

•Semiconductor Electronics •Conductive graphene films and coatings (including transparent •Electrode materia! for chemical power sources (batteries and supercapacitors) •Catalysts and sorbents •Graphene-poiymer composite materials

•Conductive inks including for 3D-printing
