Abstract:

Graphene has been attracted lots of attention for its unique properties and various applications in transistors, transparent conductors, sensors, etc. Many applications require stable and individual dispersion of graphene sheets in liquid phase. There are two ways to obtain graphene dispersion: 1) to disperse graphene powder in aqueous solution or organic solvents, 2) to exfoliate graphite into monolayer sheets in liquid phase directly. Usually, surfactants are needed to stabilize the dispersion. In this paper, recent work on preparation of graphene dispersion is reviewed, including dispersing, exfoliating, and stabilizing graphene in a variety of liquids. The dispersion of chemically derived graphene and liquidphase exfoliation of graphite are focused.

Keywords: Graphene, exfoliation, dispersion, chemically derived, graphene oxide.
