IMPLEMENTATION OF AN ACOUSTO-ELECTRIC CONVERTER. 1. DEPENDENCE OF ELECTROKINETIC PHENOMENA ON THE STRUCTURE OF MEMBRANE MATERIALS IN AQUEOUS ELECTROLYTE SOLUTIONS
The features of the flow potential in the electrolyte that are significant for implementing a liquid acousto-electric converter are presented. The electrochemistry of the flow potential in electrolytes is considered. The peculiarities of the process in the electrolyte solutions associated with the influence of the ion strength of the electrolyte and its dependence on the electrokinetic radius are noted. It is shown that at small values of the electrokinetic radius, the effect of overlapping the electric double layer occurs, leading to a sharp decrease in the absolute values of the flow potential and, consequently, to the practical impossibility of implementing the acoustoelectric transformation. The results obtained can find wide practical application.
