Enhanced tribological properties of the composite films based on ionic liquid with MoS2 nanosheets as additives

Abstract

High-performance composite films based on ionic liquid (IL) and two-dimensional MoS2 have attracted considerable attention because of their unique structure and properties, especially in the field of lubrication. Ultrathin MoS2 nanosheets obtained via a liquid exfoliation process exhibited a well dispersion in the organic solution of 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM]BF4) without the addition of any other assistants. A series of uniform composite films with different amount of MoS2 were spin-coated on the hydroxylated Si/SiO2 wafers, and the tribological performance of the composite films was studied. The load-carrying capacity and anti-wear properties of the IL films were greatly improved with the addition of MoS2 nanosheets, and the enhanced tribological properties of the compsoite films were attributed to the synergistic effect of IL and MoS2. The low-friction composite films may provide a kind of reference and be useful for the design of ultralow friction films in the practical lubrication applications.
