High-yield production of graphene by liquid-phase exfoliation of graphite.
Fully exploiting the properties of graphene will require a method for the mass production of this remarkable material. Two main routes are possible: large-scale growth or large-scale exfoliation. Here, we demonstrate graphene dispersions with concentrations up to approximately 0.01 mg ml(-1), produced by dispersion and exfoliation of graphite in organic solvents such as N-methyl-pyrrolidone. Th...
متن کاملFew-layer graphene obtained by electrochemical exfoliation of graphite cathode
Few-layer graphene has been prepared by electrochemical intercalation of graphite cathode using Na/ dimethyl sulfoxide complexes as intercalation agent. By adding thionin acetate salt into the electrolyte, the exfoliated graphite is stabilized and further exfoliated into few-layer graphene. Raman and X-ray photoelectron spectra indicate that the graphene material has lower content of defects an...
متن کاملHigh-quality thin graphene films from fast electrochemical exfoliation.
Flexible and ultratransparent conductors based on graphene sheets have been considered as one promising candidate for replacing currently used indium tin oxide films that are unlikely to satisfy future needs due to their increasing cost and losses in conductivity on bending. Here we demonstrate a simple and fast electrochemical method to exfoliate graphite into thin graphene sheets, mainly AB-s...

متن کاملHigh-yield exfoliation of three-dimensional graphite into two-dimensional graphene-like sheets.
Edge-functionalized graphite (EFG) is prepared via a "direct" covalent attachment of organic molecular wedges. The EFG is dispersed in N-methyl-2-pyrrolidone with a concentration as high as 0.27 mg mL(-1), leading to high-yield exfoliation of the three-dimensional graphite into two-dimensional graphene-like sheets.
