Owning to its large surface area and atomic thickness, graphene possesses exceptional mechanical, optical and electrical properties. Up to now, graphene and its composites/ hybrids have been widely used in various scientific fields such as drug carriers, electronics, transistors, sensors, conductive materials and so on. Unfortunately, the prospects of more extensive applications of graphene have been impeded by its poor dispersibility, processability and tunability. However, graphene can be chemically modified, and the well-chosen organic molec...
