Preparing anthracite based graphene oxide comprises e.g. preparing ultra-clean anthracite powder, adding dispersant, carrying out ultrasonication to prepare dispersion liquid, and preparing graphene oxide colloid solution.

ZHANG L, ZHANG M

Synthesis of nano-structured polymers containing graphene involves reacting graphite oxide containing bound oxygen dispersed in solvent by ultrasounds, with vinyl monomer and vinyl aromatic monomer, in presence of strong inorganic acid.

GOFFREDI G, LONGO A, VALENTINO O, FELISARI R, CASALINI A

Making graphene oxide or flakes, comprises placing graphite into water containing oxidizing agent, mechanically exfoliating graphite into graphene flakes, and separating graphene flakes from water.

BLAIR R

Graphene-based storage material, useful in a lithium ion battery, comprises graphene sheets disposed in a vertical stack, where the graphene sheets, within the vertical stack, comprise randomly-distributed defect pores.

KUNG H H, ZHAO X, HAYNER C M, KUNG M C

Synthesizing graphene comprises refluxing reaction mixture of solvent e.g. water and carbonaceous material promoting polycyclic aromatic hydrocarbon formation, collecting and directing obtained vapors to substrate and recovering graphene.

SHANKMAN R S, HANKMAN R S

Producing nano-scaled graphene platelet, useful in thermoplastic polymer nanocomposite composition, comprises contacting graphite material with molecular/atomic oxygen to obtain precursor, and chemically or physically reducing the precursor.
