Nanorheological behaviour of confined liquid layers for normal contact

Abstract

The rheological analysis of surface force apparatus experiments, usually based on lubrication theory, requires a refined modélisation taking into account the heterogeneity resulting from confinement effects. Such a model is developed and applied both in the incompressible and compressible case. It is shown that compressibility effects are essential for very thin layers. This finally leads to an oedometric thin film model to be applied for analysing the experimental results. © 1996 Eisevier Science B.V. All rights reserved.
