Abstract
Thermodynamic criteria of the “positive” (a decrease in surface hardness) and “negative” (an increase in surface hardness) Rehbinder effect are studied in terms of an earlier-proposed theory of adsorption on a solid surface that takes into account its deformation. Single-component adsorption according to Frumkin isotherm is considered. The conditions for transition from surface stretching in the presence of a “positive” Rehbinder effect to its compression and appearance of the “negative” effect is considered numerically and analytically.
