Superlubricity behavior of surfactant micelles at the nanoscale
Li, Jinjin1, Li, Jianfeng2.
Attaching appropriate molecular layers on the two sliding
surfaces is one of the most effective methods to achieve
liquid superlubricity at the nanoscale. In this paper, the
recent advances in the nanoscale superlubricity achieved
by using surfactant micelles in our group was reviewed
and discussed. First, the superlubricity conditions for
surfactant micelles is established by using atomic force
microscopy (AFM), which are the adsorption of surfactant
micelles on the two friction surfaces and the formation of
the hydration on the exposed headgroups. Second, the
nonlinear behavior of dissipation of frictional energy in
the superlubricity regime of surfactant micelles is
observed and discussed, which is attributed to the elastic
deformation of the adsorbed surfactant micelle layer.
Third, the fluorinated cationic surfactant micelle layer
exhibits the self-recovery behavior after a rupture caused
by high normal pressure, and the difference between the
rupture and recovery pressures leads to the hysteresis of
friction force. Fourth, the superlubricity of layered
materials is achieved through attaching sodium dodecyl
sulfate micelles on the friction surfaces, which is
attributed to the extremely low shear strength between
the carbon chain and layered materials. Finally, the
problems and future on the superlubricity of surfactant
micelles at the nanoscale are discussed.
