This paper presents a scalable and high-yield method for producing high-quality, un-oxidized graphene from graphite through liquid-phase exfoliation. The authors demonstrate that graphene dispersions with concentrations up to ~0.01 mg/ml can be achieved by exfoliating graphite in organic solvents such as N-methyl-pyrrolidone (NMP). The energy required for exfoliation is balanced by the solvent-graphene interaction, leading to individual graphene sheets with yields of up to 12% by mass. The presence of individual graphene sheets is confirmed using absorption spectroscopy, transmission electron microscopy, and electron diffraction. The absence of defects or oxides is verified by X-ray photoelectron, infra-red, and Raman spectroscopies. The method is versatile and can be used to produce conductive, semi-transparent films and composites, opening up potential applications in device fabrication, sensors, and liquid-phase chemistry. The process involves sonication and centrifugation to disperse and exfoliate graphite, followed by characterization to ensure the quality and yield of the graphene.This paper presents a scalable and high-yield method for producing high-quality, un-oxidized graphene from graphite through liquid-phase exfoliation.
