Curvature Dependence of Interfacial Properties for Associating Lennard–Jones Fluids: A Density Functional Study

Classical density functional theory is used to study the associating Lennard–Jones fluids in contact with spherical hard wall of different curvature radii. The interfacial properties including contact density and fluid-solid interfacial tension are investigated. The influences of associating energy, curvature of hard wall and the bulk density of fluids on these properties are analyzed in detail. The results may provide helpful clues to understand the interfacial properties of other complex fluids.
