Influence of Vibrations in the Interfacial Layer on the Wettability of an Adhered Material of Interfacial Formations in Systems with d and f Elements

Abstract

The effect of local vibration in an interfacial layer of a heterogeneous liquid system on the wettability of the material of interfacial formations based on a d- or f-metal di-(2-ethylhexyl)phosphate salt adhered to glass has been studied. It has been demonstrated that, in the field of mechanical vibrations, one can obtain a hydrophobic material with a desired wetting angle value. It has been established that the influence of mechanical vibrations is caused by changes in the hydrodynamic situation in the transition region and is a result of complex interplay mainly between hydrodynamic and coagulation processes in the interfacial layer of the di-(2-ethylhexyl)phosphoric acid–solvent/aqueous solution of a d- or f-metal salt system. The wettability of the material of interfacial formations adhered to glass turns out to depend on the parameters of the force field (vibration frequency and amplitude), the design features of the experimental setup, and the composition of the system.
