摘要

研究表明，在液/液异质体系界面层中合成的材料的润湿性可以通过局部振动来控制。研究了有机酸、金属和溶剂的性质对粘附在不同基底上的材料的接触角的影响。研究发现，在局部振动的作用下，合成的材料结构更有序、粗糙度更高、含水量更低，因此接触角更大。在所研究的基底上获得了接触角为 100-163° 的疏水涂层，涂层在大气条件下可长期保持憎水特性。

Control over the Wettability of a Material by Local Vibration on the Interfacial Layer

It has been shown that the wettability of a material synthesized in the interfacial layer of a liquid/liquid heterogeneous system can be controlled by local vibrations. The influence of the nature of an organic acid, a metal, and a solvent on the contact angle of a material adhered to various substrates has been studied. It has been found that, under local vibrations, a material is synthesized with a more ordered structure, a higher roughness, a lower water content, and, as a consequence, a larger contact angle. Hydrophobic coatings with contact angles of 100–163° have been obtained on the studied substrates, with the coatings retaining their water-repellent properties under atmospheric conditions for a long time.

期刊介绍： Colloid Journal (Kolloidnyi Zhurnal) is the only journal in Russia that publishes the results of research in the area of chemical science dealing with the disperse state of matter and surface phenomena in disperse systems. The journal covers experimental and theoretical works on a great variety of colloid and surface phenomena: the structure and properties of interfaces; adsorption phenomena and structure of adsorption layers of surfactants; capillary phenomena; wetting films; wetting and spreading; and detergency. The formation of colloid systems, their molecular-kinetic and optical properties, surface forces, interaction of colloidal particles, stabilization, and criteria of stability loss of different disperse systems (lyosols and aerosols, suspensions, emulsions, foams, and micellar systems) are also topics of the journal. Colloid Journal also includes the phenomena of electro- and diffusiophoresis, electro- and thermoosmosis, and capillary and reverse osmosis, i.e., phenomena dealing with the existence of diffusion layers of molecules and ions in the vicinity of the interface.
