Low friction and rotational dynamics of crystalline flakes in solid lubrication
Solids at incommensurate contact display low-friction, ’superlubric’, sliding. For graphene flakes on a graphite surface, superlubric sliding is only temporary due to rotation of the flakes from incommensurate to commensurate contact with the substrate. We examine this rotational channel of friction in a prototype geometry of mesoand macroscopic solid lubrication. By molecular dynamics simulati...
متن کاملAn asymmetric dimer in a periodic potential: a minimal model for friction of graphene flakes
We discuss the friction and motion of a model of a dimer with asymmetric interactions with a substrate potential. Starting from the consideration that a rigid dimer with spacing equal to half of the period of the potential has exactly zero static friction like the infinite incommensurate Frenkel Kontorova model, we show how stick-slip behaviour and friction arise as a function of asymmetry. We ...
متن کاملSuperlubricity of Graphite Induced by Multiple Transferred Graphene Nanoflakes
2D or 3D layered materials, such as graphene, graphite, and molybdenum disulfide, usually exhibit superlubricity properties when sliding occurs between the incommensurate interface lattices. This study reports the superlubricity between graphite and silica under ambient conditions, induced by the formation of multiple transferred graphene nanoflakes on the asperities of silica surfaces after th...
متن کاملPuckering stick-slip friction induced by a sliding nanoscale contact.
An atomic force microscope reveals that the sliding of a nanotip on a graphite surface occurs through a nanoscale stick-slip mechanism. The angle between the sliding direction and a stiff crystallographic axis determines the periodicity of the slip events defining domains of various friction properties. The experimental data are interpreted using the reaction rate theory, with the energy barrie...
متن کاملGraphene Nanoflakes: Superlubricity of Graphite Induced by Multiple Transferred Graphene Nanoflakes (Adv. Sci. 3/2018)
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 sl...
