We systematically discuss frictional properties occurring in atomic-force microscope (AFM) tip on graphite system, the graphite/C60/graphite system, and the C60 intercalated graphite system. Several possible mechanism to induced superlubricity of C60 intercalated graphite system are proposed and discussed. It can be expected that the superlubricity is induced by internal sliding between close-packed C60 monolayers and graphite layers. Our results propose one of the simple guidelines of designing practical superlubric system—reduction of the contact area between intercalated C60 and graphite sheet to the point-like contact. We anticipate our novel lubrication system to be a startpoint for developing more practical superlubricant using intercalated graphite, which will contribute to solving the energy and environmental problems.
