摘要

石墨烯基材料具有巨大的摩擦学应用潜力。石墨烯的独特性能,如低剪切阻力、高刚度和导热性,使其成为一种有吸引力的材料,用于改善广泛工业应用中的润滑剂性能,从车辆到家用冰箱和工业机械,如齿轮箱、大型压缩机等。目前的综述旨在从工程角度考虑,将更多的重点放在商用石墨烯和完全配方的润滑油上,而不是实验室规模生产的石墨烯和不含添加剂的基础油。使用含石墨烯添加剂的润滑油可以提高机械效率,从而使家用冰箱的能耗和二氧化碳排放量降低20%,ICE车辆的能耗和二氧化碳排放量降低6%。除了纯粹的摩擦减少之外,对这些好处的潜在影响也进行了简要的介绍和讨论。

Review of Graphene-Based Materials for Tribological Engineering Applications
Graphene-based materials have great potential for tribological applications. Graphene’s unique properties such as low shear resistance, high stiffness, and thermal conductivity make it an attractive material for improving the properties of lubricants in a wide range of industrial applications, from vehicles to house refrigerators and industrial machinery such as gearboxes, large compressors, etc. The current review aims to give an engineering perspective, attributing more importance to commercially available graphene and fully formulated lubricants instead of laboratory-scaled produced graphene and base oils without additives. The use of lubricants with graphene-based additives has produced e.g., an increase in mechanical efficiency, consequently reducing energy consumption and CO2 emissions by up to 20% for domestic refrigerators and up to 6% for ICE vehicles. Potential effects, other than purely friction reduction, contributing to such benefits are also briefly covered and discussed.
