Application of the methods of the dilational surface rheology to adsorbed and spread layers of nano- and microparticles at liquid – fluid interfaces gives insight in the structure and formation mechanism of the layers. This is especially important in view of the limited applicability of standard experimental methods of the interface science to heterogeneous surface layers. The literature in this field almost has doubled for the last few years and recent articles are discussed in this review. All the systems are divided into two groups of the layers of solid and soft particles depending on the influence of the particle deformability on surface properties. In the latter case the peculiarities of surface dilational rheological properties of adsorbed and spread layers of polylelctrolyte/surfactant aggregates, solid particles grafted by polymers, polymer microgels, and protein fibrils and microgelsare briefly discussed together with the merits and drawbacks of the existing experimental methods of the surface dilational theology.

液-液界面处纳米和微颗粒单层的扩张流变学

将膨胀表面流变学方法应用于液-液界面处吸附和扩散的纳米和微粒层,可以深入了解层的结构和形成机理。鉴于界面科学的标准实验方法对异质表面层的适用性有限,这一点尤其重要。在过去的几年中,该领域的文献几乎翻了一番,并且在这篇评论中讨论了最近的文章。根据颗粒变形性对表面性能的影响,将所有系统分为固体颗粒层和软颗粒层的两组。在后一种情况下,表面膨胀流变特性具有特殊性 简要讨论了聚电解质/表面活性剂聚集体的吸附和铺展层,由聚合物,聚合物微凝胶,蛋白质原纤维和微凝胶接枝的固体颗粒,以及现有的表面膨胀神学实验方法的优缺点。
