▎ 摘　　要

NOVELTY - Ionic liquid-based nanofluid cutting fluid comprises ionic liquid and nanoparticles in a mass fraction of 0.002-0.5%. The nanoparticles include graphene, carbon nanotubes, molybdenum disulfide, tungsten disulfide, and boron nitride. USE - Ionic liquid-based nanofluid cutting fluid. ADVANTAGE - The ionic liquid-based nanofluid cutting fluid has better dispersion stability, better lubricating performance, higher permeability, better penetration performance, better heat transfer performance and higher heat capacity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing ionic liquid-based nanofluid cutting fluid, which involves adding nanoparticles to the ionic liquid ultrasonic dispersion, and then homogenizing to form a uniform and stable suspension.
