NOVELTY - A lubricant oil containing graphene comprises lubricant grease and a plurality of modified graphene powders accounting for 0.001 wt% to 10 wt% and evenly dispersed in the lubricant grease. Each modified graphene powder comprises at least a surface modification layer, each surface modification layer at least includes a surface modifier which having at least two functional groups respectively located at two ends of the surface modifier, wherein one of the at least two functional groups forms chemical bond with the organic functional groups on the surface of the graphene powder, and the other of the at least two functional groups forms the surface property of the modified graphene powder, and the modification layer can provide high affinity for the modified graphene powder with lubricant oil.
