Abstract

The frictional behavior of the C₆₀ intercalated graphite films with a large size of 2.3 × 2.3 mm² is reported. The C₆₀ intercalated graphite films consist of alternating close-packed C₆₀ monolayers and graphite layers (graphenes), and thus infinite sliding planes are formed between each C₆₀ monolayer and graphene. The intercalation of C₆₀ molecules into graphite films results in superlubricity where both static and dynamic frictional forces are observed to be zero. [DOI: 10.1380/ejssnt.2005.21]
