摘    要:以膨胀石墨为原料,采用不同溶剂,通过液相超声直接剥离法制备多层石墨烯,利用透射电子显微镜、原子力学显微镜对其形貌进行了表征,在多功能往复摩擦磨损试验仪上研究了石墨烯石蜡分散体系的摩擦学性能。通过扫描电镜、能谱仪分析了磨痕形貌及表面元素组成。结果表明:多层石墨烯作为液体石蜡添加剂表现出良好的减摩抗磨性能,主要是因为多层石墨烯在磨损表面形成的物理吸附膜与摩擦化学反应膜的共同作用。

关 键 词:液相超声剥离   多层石墨烯   液体石蜡   摩擦学性能

Abstract:The multi-layer graphene, thickness being 10-180 nm, was prepared by the method of liquid ultrasonic stripping in deionized water, n-butanol, dimethyl sulfoxide and characterized by transmission electron microscope (TEM) and atomic force microscope (AFM). The tribological properties of multi-layer graphene as lubricant additive were investigated using a multi-functional reciprocating friction and wear tester. By the addition of multi-layer graphene in paraffin liquid, the friction coefficient was decreased and the antiwear ability was improved. It is concluded that the formation of physisorption films and tribochemistry reaction films on the worn surface can explain the excellent friction and wear properties of multi-layer graphene.
Keywords:liquid ultrasonic stripping  multi-layer graphene  paraffin liquid  tribological property
