A graphene masterbatch for modification of frost-resistant plastic lubricants

The paper describes the results of a study of the graphene concentration effect on the viscosity of a base oil for preparing plastic lubricants. It was established that the viscosity of the graphene masterbatch reaches the viscosity of the plastic lubricant at 9-11 wt% for few-layered graphene and 5-8 wt% for multi-layered one. Moreover, at graphene concentrations of 0.1 wt% or more, the wear spot diameter decreases by at least 50 %, whereas the load wear index and bearing strength increase almost 3-fold and 4-fold, respectively.
