Surfactant-free exfoliation of graphite in aqueous solutions

Author affiliations

Abstract

We report an ultrasound exfoliation of graphite in a weakly basic solution to produce multi-layer graphene dispersion. A unique feature of this process is that no surfactant was added to stabilize the exfoliated graphene in water. The concentration of the graphene dispersion prepared by this approach can be up to 0.02 mg mL−1 and it was stable at room temperature for several months.
