Nanomaterials as oil-based lubricant additives improve the tribological properties of oils, and its enormous potential in oil-based applications has attracted increasing attention. However, 2D materials have limited applications in industry due to its high price. 3D graphene (3D Gr) has become a substitute of 2D graphene because of its low price. Hexagonal boron nitride (h-BN) is known as white graphene and is a material with potential lubrication applications. In this paper, the combination of the two different dimensions materials not only plays a significant role in reducing environmental pollution, but also exerts excellent properties of both materials. The results show that the mixed-dimensional nanomaterials have good macroscopic lubricity under oil.
