The frictional properties of molecules physisorbed on a graphite surface were investigated on the macroscale using a pin-on-plate tribometer and on the nanoscale using atomic force microscopy (AFM). Hydrodynamic lubrication was observed even at a contact pressure of about 1 GPa under the AFM tip. Selection of the Stribeck parameter of η_<eff>V/(W/R), which accounts for the change in effective viscosity, is proved effective for comparing the frictional properties of the physisorbed layers of self-organized molecules on nanoscale with the properties on macroscale.
