1. A method of preparing an aqueous graphene dispersion, said method comprising:
providing a composition comprising a graphite composition comprising natural graphene, at least one non-ionic surface active polymeric component, said polymeric component a block copolymer of oxyethylene and oxypropylene, and an aqueous medium; sonicating said composition to exfoliate said graphite composition and disperse said graphene component within said aqueous medium; and centrifuging said sonicated composition to separate said dispersed graphene component therefrom. |
