A modified lubricant includes lubricant grease and nano-graphite plates dispersed thoroughly in the lubricant grease. The content of the nano-graphite plates is 0.0001 wt % to 10 wt %. Each nano-graphite plate has a length or a width between 1 and 100 μm, a thickness within 10 nm and 100 nm, and N graphene layers stacked together and a surface modifying layer disposed on the top or bottom of the nano-graphite plates, wherein N is 30 to 300. The surface modifying layer has a surface modifying agent which includes at least two functional groups located at two ends of the surface modifying agent, one of the two functional groups is chemically bonded with certain organic functional group remaining on the surface of the nano-graphite plate, and the other of the two functional groups forms the functional surface of the nano-graphite plate. |

1. A modified lubricant, comprising:
lubricant grease; and a plurality of nano-graphite plates dispersed thoroughly in the lubricant grease, wherein the content of the nano-graphite plates is 0.0001 wt % to 10 wt % in the lubricant grease, each nano-graphite plate has a length or a width between 1 and 100 μm, and a thickness within 10 nm and 100 nm, and each nano-graphite plate has N graphene layers stacked together and at least one surface modifying layer disposed on the top and/or bottom of the nano-graphite plates, wherein N is 30 to 300, the surface modifying layer has a surface modifying agent which includes at least two functional groups located at two ends of the surface modifying agent, one of the two functional groups is chemically bonded with certain organic functional group remaining on the surface of the nano-graphite plate, and the other of the two functional groups forms the functional surface of the nano-graphite plate, wherein the coupling agent has a chemical structure of Mx(R)y(R′)z, M is a metal element, R is a hydrophilic functional group, and R′ is a hydrophobic functional group, 0≦x≦6, 1≦y≦20, and 1≦z≦20. |
