Abstract

The stickiness of acacia gum was used to assist in the ball milling of graphite in aqueous media. Graphite is successfully exfoliated through a “sticky tape” mechanism, to give a 2.06 mg mL−1 aqueous dispersion of graphene. PEG6000 doped with 0.4 wt% of as-prepared graphene nanosheets (GN) exhibited obviously growing enthalpies and increasing thermal conductivity by 260% over pure PEG6000.
