On the mechanism of solvation forces

Abstract

The generally observed experimental features of solvation forces were considered. It was shown that the phonon mechanism of long range surface forces can be applied directly to explain solvation forces. In terms of this mechanism, the oscillations of interaction forces arise due to spatial dispersion; they result in oscillations of collective vibration states density varying with film thickness. The peculiarities of solvation forces revealed in different systems and the correlation between oscillation parameters and the characteristics of interacting media have been discussed. © Springer-Verlag 1999.
