Graphene Nanoflakes: Superlubricity of Graphite Induced by Multiple Transferred Graphene Nanoflakes (Adv. Sci. 3/2018)

摘要

Superlubricity between graphite and silica is achieved under ambient conditions, induced by the formation of multiple transferred graphene nanoflakes (GNFs) on a silica surface. As reported by Jinjin Li and co‐workers in article number 1700616 , the friction coefficient could be reduced to 0.0003 at a maximal local contact pressure of 700 MPa because of the extremely weak interaction and easy sliding between transferred GNFs and graphite in the incommensurate contact.
