New graphene/ionic liquid nanolubricants

In this work, we have prepared new graphene/ionic liquid dispersions by adding a 0.1wt.% proportion of 1-2 layers graphene (G1) or 1-10 layers graphene (G2) to the ionic liquid 1-octyl-3-methylimidazolium tetrafluoroborate (IL). The new dispersions (IL+G1) and (IL+G2) have been used as external lubr...
