Solvent-free ionic molybdenum disulfide (MoS 2 ) nanofluids with self-healing lubricating behaviors

Solvent-free ionic molybdenum disulfide (MoS 2 ) nanofluids with self-healing lubricating behaviors. Nanoscale ionic materials (NIMs) which have a core-corona-canopy structure are innovative materials that have drawn great attention. In our work, homogeneous and stable solvent-free ionic MoS 2 nanofluids, falling under the category of typical NIMs, were obtained by surface functionalizing and ionically tethering nanoscale graphite-like MoS 2 from hydrothermal synthesis. Rheological results and the fluidity of nanofluids showed the Newtonian liquid behaviors of the nanofluids, which is favorable for lubrication. Furthermore, nanotribological results reveal that the nanofluids show lower, more stable friction coefficients and self-healing lubricating behaviors under a certain limit of normal load. The nanofluids can protect the substrates from scratching an
