摘要：

The wetting of the planar interface between air saturated with octane vapor and an aqueous solution by octane is investigated by ellipsometry and interfacial tension measurements. The interfacial interactions are varied through the concentration of the uncharged solute (glucose). We observe abrupt and continuous increases of the octane coverage with growing solute concentration. This we attribute to short- and long-range (dispersion) interactions, respectively. The continuous thickness growth is analyzed as a critical wetting transition.
