NOVELTY - Ternary nano self-lubricating composite material comprises nanometer cerium oxide, fluorinated-graphene oxide and carbon nano-tube. The fluorinated-graphene oxide has excellent dispersing characteristics in the reaction solution, and the fluorinated-graphene oxide is used as a surfactant to effectively disperse the carbon nanotubes with poor dispersibility. The carbon nanotubes are mixed with fluorinated-graphene oxide by pi - pi action and the fluorinated-graphene oxide and the carbon nanotubes are mixed to form an interpenetrating network structure. The in-situ growth of nano-cerium dioxide particles, nano-cerium oxide particle in composite by fluorination-graphene oxide/carbon nanotube nano composite by hydrothermal reduction by adsorption of cerium (III) ion by a functional group on the surface of the fluorinated-graphene oxide. The particles are hexagonal with the particle size distribution of 3-3.5 nm. USE - Used as ternary nano self-lubricating composite material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing ternary nano self-lubricating composite material comprising: (i) adding certain amount of fluorinated-graphene oxide into a mixed solution of ethanol and water and ultrasonically mixing to a uniform solution and adding certain amount of carbon nano-tubes and ultrasonically mixing to homogeneous solution to obtain mixed solution of fluorinated-graphene oxide/carbon nanotube nano-composite (FGO/CNTs nanocomposite-1); (ii) taking certain amount of cerium(III) nitrate hexahydrate and ultrasonically dispersing in a mixed solution of ethanol and water to obtain mixed solution-2, mixing the mixed solution-2 into the mixed solution-1 at a constant rate under magnetic stirring conditions and magnetically stirring to obtain mixed solution-3, taking certain amount of sodium hydroxide and adding into the mixed solution-3 to obtain precursor solution; (iii) transferring the precursor solution to the polytetrafluoroethylene liner, sealing the inner liner in a stainless steel jacket, reacting at 140-180 degrees C for 12 hours and naturally cooling the reactor to room temperature; and (iv) centrifuging the product using absolute ethanol, washing in distilled water and freeze-drying.
