Abstract
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.
