Abstract: 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 molecules with active
functional groups would react with graphene to form low-dimensional graphene-organic architectures. The
controlled functionalization of organic molecules onto the defective sites of graphene is a very effective route for fabrication of graphenebased
composite materials. The aim of this article is to present an overview of the surface functionalization methodologies which are
valuable for the selective construction of highly functionalized graphene with controllable properties. The interactions between graphene
and organic molecules were discussed in detail. We hope to provide some useful references and enlightened views for scientific research
groups.
