Diffusiophoresis in electrolyte solutions and its application to the formation of surface coatings

Abstract

1. Both potential and concentration gradients can give rise to particle motion in electrolyte solutions, movement of the latter type being designated as diffusiophoresis. 2. A theory of diffusiophoresis has been developed and checked against the results of laboratory experiments. 3. Studies on diffusiophoresis have been limited, despite the significance of the effect itself. 4. Unless account is taken of this effect it is impossible to understand the technological processes involved in the formation of latex film by ion deposition on a base substrate. 5. By using diffusiophoretic methods it is possible to lay down metallopolymeric and other types of films on any surface. These procedures can even be applied in cases in which the base is conducting, thus ruling out the use of electrophoretic methods.
