[2Ep05] Behavior of Physisorbed Molecules at Solid-liquid Interface

*Koji Miyake¹ (1. National Institute of Advanced Industrial Science and Technology)

The effect of physisorbed molecules at solid-liquid interface on frictional properties were investigated. In the case of planer molecules, the frictional properties on nanoscale depended on the 2-dimensional molecular structure of molecules. The change in effective viscosity with contact pressure might influence the nanoscopic and macroscopic frictional property. In the case of lubrication film composed of nonpolar base oil and polar additives, the physisorbed nonpolar base oil molecules might contributed to the friction reduction.
