▎ 摘  要

NOVELTY - Lubricating composition comprises: ionic liquid; and unmodified graphene particles dispersed in the ionic liquid. The ionic liquid is dicyanamide of 1-ethyl-3-methylimidazolium, and the viscosity of the composition is increased with increasing temperature. USE - The composition is useful as a lubricating agent in metal/ceramic contacts or metal/metal contacts (all claimed). ADVANTAGE - The composition utilizes unmodified graphene particles dispersed in the ionic liquid which result in a fluid free of toxic elements and whose viscosity increases with temperature under the action of a high shear gradient, as well as addition of graphene decreases friction between surfaces, preferably in metal/ceramic or metal/meta contacts.
