石墨烯(Graphene)是一种具有优异的电学、热学、力学等物理化学性能的二维碳纳米材料。其应用涵盖电池、传感器、超级电容器和复合材料等领域。但石墨烯片层之间具有很强的π-π相互作用以及高比表面能导致其具有很强的化学惰性,易趋于聚集,限制其优异的性能的发挥。因此石墨烯必须经过适当的改性以促进其在溶剂或基体树脂的分散,进一步拓展石墨烯的应用范围。石墨烯表面改性方式一般分为化学改性(共价键改性)、物理改性(非共价键改性)以及元素掺杂改性。本文从这三种改性方式综述了石墨烯的表面处理方法目前取得的进展,并展望了石墨烯改性未来的发展。
Graphene is a kind of two-dimensional carbon nanomaterial with excellent physical and chemical properties. The applications of graphene covered batteries, sensors, supercapacitors and compo-sites. However, the strong π-π interaction between the graphene sheets and the high specific surface energy limit its excellent performance, because of the strong chemical inertness and aggregate. Therefore, graphene must be appropriately modified to promote its dispersion in a solvent or matrix resin, expanding the application. The surface modification methods of graphene are generally classified into chemical modification (covalent bond modification), physical modification (non-covalent bond modification), and element doping modification. In this paper, the preparation methods of graphene are reviewed from these three modification methods, and it prospected the future development.
