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.

钢/钢接触中分散在PAO4中的3D石墨烯和2D六方氮化硼的协同润滑行为

纳米材料作为油基润滑剂添加剂可改善油的摩擦学性能，其在油基应用中的巨大潜力已引起越来越多的关注。但是，由于二维材料价格高昂，因此在工业上的应用受到限制。3D石墨烯（3D Gr）因其低廉的价格已成为2D石墨烯的替代品。六方氮化硼（h-BN）被称为白色石墨烯，是具有潜在润滑应用的材料。在本文中，两种不同尺寸的材料的组合不仅在减少环境污染方面发挥了重要作用，而且还发挥了两种材料的优异性能。结果表明，混合纳米材料在油下具有良好的宏观润滑性。
