Abstract:

Graphene research develops dramatically in diverse fields，such as materials，physics，chemistry，biology and so on，and mainly concentrates on its synthesis，functionalization and applications. However，graphene also possesses some drawbacks，such as low solubility and poor dispersion that limit its performance，therefore functionalization of graphene-sheets is of crucial importance for making the best of their potential applications. Non-covalent functionalization is paid much attention due to its less damage and full maintenance of the intrinsic structure and properties of graphene. The recent research about non-covalent functionalization of graphene，including π-π interaction，hydrophobic attraction between surfactant and graphene，and hydrogen bonding interactions，is reviewed and applications of these functional graphene，such as electrode materials，electrocatalysis，field effect transistors and transparent conductors are outlined and prospected.
