NOVELTY - Preparing nano-hybrid material modified epoxy resin self-lubricating composite coating comprises e. g. disposing aqueous solution of graphene oxide, adding carbon nanotubes, ultrasonically mixing until uniform, and placing the obtained solution in a reaction kettle, performing hydrothermal reaction and freeze-drying overnight to obtain carbon nanotube/graphene oxide hybrid material, dispersing the carbon nanotube/graphene oxide hybrid material and ammonium tetrathiomolybdate in a solvent of N,N-dimethylformamide, mixing the ultrasonic dispersion uniformly, dropping the hydrazine hydrate, placing the obtained mixed solution in the reaction vessel, performing hydrothermal reaction, centrifuging and washing repeatedly with deionized water and absolute ethanol and drying to obtain carbon nanotubes/graphene oxide/molybdenum disulfide nano-hybrid materials, adding epoxy resin and curing agent in a mass ratio of 1:1 into absolute ethanol and acetone solvent and mixing uniformly. USE - The method is useful for preparing nano-hybrid material modified epoxy resin self-lubricating composite coating. ADVANTAGE - The method has mild reaction condition, and is simple, and easy, and suitable for large scale production. The coating is compact, uniform and exhibits a low friction coefficient and high anti-wear performance.
