采用油酸对液相剥离的石墨烯片进行改性，并将其分散在润滑油中作为添加剂。采用四球摩擦磨损试验机研究了含石墨烯润滑油的摩擦学性能。优化的石墨烯浓度为0.02- 0.06wt%的润滑剂显示出增强的摩擦和抗磨性能，摩擦系数和磨痕直径分别降低了17%和14%。
Liquid phase exfoliated graphene sheets were modified by oleic acid and dispersed in lubricant oils as additives. The tribological behaviours of graphene-contained oils were investigated using a four-ball tribometer. The lubricant with optimized graphene concentrations of 0.02-0.06 wt% showed enhanced friction and anti-wear performance, with friction coefficient and wear scar diameter reduced by 17% and 14%, respectively.
