Liquid-exfoliated graphene can be stably dispersed in water and concurrently maintain its high quality (average 1 nm thick, low content of defects and oxides). The high stability is attributed to the reduction of flake size and thus the enhanced edge effects. This work opens up a whole new vista on how to disperse graphene.
