▎ 摘　　要

NOVELTY - Preparing engine oil additive with bionic non-smooth surface structure, comprises mixing graphene oxide and ferrocene in a solvent at specific mass ratio, and then subjecting the mixture to ultrasonic treatment, washing, and drying to obtain final product. USE - The method is useful for preparing engine oil additive with bionic non-smooth surface structure. ADVANTAGE - The additive: involves construction of graphene oxide-ferrocene nanocomposite on the basis that graphene oxide has a special two-dimensional nano-layered structure, high mechanical strength and excellent thermal conductivity, thus the introduction of ferrocene can reduce the microscopic contact area of graphene oxide sheets, playing the role of reducing friction and drag and improving lubrication performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for engine oil additive with bionic non-smooth surface structure prepared by above method.
