Abstract

A calculation is performed to quantify the dispersion interactions associated with a spherical cap on a semi-infinite solid. Expressions are derived for the difference between the actual value of the interfacial energy of the spherical cap/semi-infinite solid interface and the value which assumes the phases to be of infinite extent. Applying these considerations to macroscopic, noncompletely wetting liquids on flat solids indicates that neglect of the finite extent of the liquid is normally appropriate.
