Influence of molecular processes at liquid interfaces on dynamic surface tensions and wetting kinetics

The application of theories on the wetting kinetics of surfactant solutions requires accurate knowledge of the adsorption kinetics of the surfactant molecules at the involved interfaces. Studies on dynamic surface tensions give access to a quantitative understanding of the mechanisms governing this part of the complex wetting process. It is shown that besides the surface activity and the bulk concentration of a surfactant, the adsorption mechanism and the peculiarities of the interfacial dynamics play a significant role at the liquid–air interface. Due to interfacial processes, such as change in orientation or aggregation of molecules in the surface layer, differences in the adsorption time of more than one order of magnitude are observed.
