摘要

动态扩张粘弹性是界面层的一个重要物理特性,因为它影响着液体薄膜、泡沫和乳液等多相系统的动态和稳定性。稀释粘弹性取决于许多因素。研究较少但非常重要的因素包括溶液成分在两种接触液体中的溶解度、混合吸附层中同时存在两种溶液成分以及界面曲率。在本综述中,我们考虑了以前提出的模型的一些新发展,这些模型可用于分析新的实验数据。在存在这些效应的情况下,扩张粘弹性的行为变得更加复杂,需要更多的参数来描述。另一种方法是使用现象学模型,这种模型不确定特定的弛豫过程,但提出了对扩张粘弹性的一般描述。

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.
