The frictional behavior of the C60 intercalated graphite films with a large size of 2.3×2.3mm2 is reported. The C60 intercalated graphite films consist of alternating close-packed C60 monolayers and graphite layers (graphenes), and thus many sliding planes are formed between each C60 monolayer and graphene. The intercalation of C60 molecules into graphite films results in superlubricity where frictional forces are observed to be stationarily zero.
