摘　　要：氟化石墨烯(FG)作为1种石墨烯衍生物,兼具石墨烯材料低剪切、高承载的力学性能以及氟化碳材料独特的理化性能.相较于其他固体润滑材料,FG在极压性与减摩抗磨性等方面表现出了巨大的性能优势,成为当前固体润滑领域研究的热点材料.本文中梳理总结了近年来FG在制备方法、修饰改性、分散稳定性、润滑机制与润滑应用等方面的研究进展以及在应用过程中存在的主要问题,并对未来FG在摩擦学领域的主要研究方向与应用前景提出了一些建议和展望.Research has shown that FG’s physicochemical properties are closely related to its honeycomb carbon skeleton structure and carbon-fluorine bond strength.Therefore,this article first systematically summarizes the influence of fluorine content and carbon-skeleton microstructure on FG’s lattice parameters,chemical stability,and physical properties;then,it discusses the possible regulation mechanism of its mechanical properties and tribological characteristics.FG’s preparation process is a crucial factor affecting and regulating its microstructure and physicochemical properties.Therefore,this article subsequently summarizes the latest research progress on preparation of FG based on the two basic strategies(exfoliation and fluorination),expecting to provide guidance for the development of FG’s new preparation processes and hoping to obtain FG materials suitable for different lubrication applications at controllable costs.FG materials have deficiencies in film formation on substrate,medium dispersion,and non-covalent binding strength,which limit their applications in lubrication,corrosion protection,and material reinforcement.Therefore,this article summarizes the main process routes and problems faced in FG material’s physical and chemical modifications,aiming to provide feasible solutions for controllable modification and functionalization.Clarifying the lubrication mechanism is the key to exploring FG material’s application in lubrication and protection fields.Therefore,this article systematically summarizes the research progress on micro and macro lubrication mechanisms of FG,further clarifies the key factors affecting its lubrication performance,and outlines FG’s main application progress in tribological fields,including its applications as water-based or oil-based lubricant additives,polymer fillers,and solid lubricating coatings.Finally,based on the current research hotspots in tribological fields and FG’s reported advantages and disadvantages in lubrication capacities,this article discusses FG’
