Dynamic dilational viscoelasticity of surfactant layers at liquid–liquid interfaces
Dynamic dilational viscoelasticity is an important physical characteristic of interfacial layers because it influences the dynamics and stability of multiphase systems, such as thin liquid films, foams and emulsions. Dilational viscoelasticity depends on many factors. Less studied, but very important, factors are the solubility of the solution components in two contacting liquids, the simultaneous presence of two solution components within a mixed adsorption layer and the curvature of the interface. In this review, we considered several new developments of previously proposed models, which can be used for the analysis of new experimental data. In the presence of such effects, the behaviour of the dilational viscoelasticity becomes more complicated and requires more parameters for its description. An alternative way is to use phenomenological models, which do not identify the particular relaxation processes but propose a description of the dilational viscoelasticity in general terms.
期刊介绍:
Current Opinion in Colloid and Interface Science (COCIS) is an international journal that focuses on the molecular and nanoscopic aspects of colloidal systems and interfaces in various scientific and technological fields. These include materials science, biologically-relevant systems, energy and environmental technologies, and industrial applications.
Unlike primary journals, COCIS primarily serves as a guide for researchers, helping them navigate through the vast landscape of recently published literature. It critically analyzes the state of the art, identifies bottlenecks and unsolved issues, and proposes future developments.
Moreover, COCIS emphasizes certain areas and papers that are considered particularly interesting and significant by the Editors and Section Editors. Its goal is to provide valuable insights and updates to the research community in these specialized areas.
