石墨烯非共价键功能化及应用研究进展

Research progress of non-covalent functionalization and applications of graphene

为了扩展石墨烯的应用范围,克服石墨烯在溶液中难于溶解和难以分散等缺陷,石墨烯的表面功能化处理势在必行。而非共价键功能化由于对石墨烯结构的非破坏性可以更好地保持发挥石墨烯本身的优异性能而备受研究者的重视。本文重点综述了近年来石墨烯在非共价键功能化研究方面的进展,包括π-π相互作用、表面活性剂与石墨烯之间的疏水作用和氢键作用,并对非共价键功能化石墨烯在电极材料、电催化、场效应晶体管和透明导体方面的应用研究进行了简要的介绍。最后对石墨烯在非共价键功能化方面的发展前景进行了展望和预测。

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.
