Abstrakt

We apply density functional theory to study the interfacial properties of a phase-separating binary fluid of ultrasoft particles, whose interaction potentials belong to the family of the so-called generalized exponential models (GEM). By using the formalism of the density functional theory within the mean-field approximation, we investigate the equilibrium density profiles for each component at the free interface as well as at a repulsive, flat wall. We show that the studied system can lead to first-order wetting transition which is characterized by a layering-like behaviour due to the clustering properties of GEM particles.
