We performed the exfoliation of graphene by a co-mixing of graphite (1 mg/ml) and gum Arabic (1 mg/ml) in a mixing volume of 400 ml.
To investigate the possibility of graphene exfoliation in a bio-surfactant medium, we have produced graphene from the co-mixing of graphite and gum Arabic.
As conclusion, we have shown that it is possible to produce gum Arabic-modified graphene from the co-mixing of graphite and gum Arabic in a commercial kitchen mixer.

The graphite balls manufactured with reasonable mix-ratio of graphite powders and process method show very good properties.
The CPE was prepared by mixing 1.0 g of graphite powder and 0.5 ml of paraffin oil in a small agate mortar, and this mixture was then homogenized.
Graphene oxide solution was prepared by mixing 50 mg of graphite oxide in 30 mL of ethanol followed by sonication for a period of 30 min.
Bare carbon paste electrodes (CPEs) were prepared by mixing 400 mg of graphite powder and 150 mg solid paraffin with a mortar and pestle.
AMS targets of GCI and GCIP each produced a mix of nanocrystalline graphite (or g-C), and Fe3C crystal, intense C− current consistently, with only traces of isotopic fragmentation, and accurately estimated the Fm values.
The GCI and GCIP were also a mix of nanocrystalline graphite (or g-C) and Fe3C crystal based on FT-IR (C=C), Raman spectra (D, G, G′, and D + G bands), and XRD (Fe3C crystal).
Because our FT-IR and Raman results suggested that ICM, GCI, and GCIP consisted of a mix of nanocrystalline graphite (or g-C), and Fe3C crystal, we further examined the AMS targets using XRD to distinguish between crystal and amorphous structures.
