INFLUENCE OF AN ELECTRIC FIELD ON THE STRUCTURE OF NONAQUEOUS DISPERSION SYSTEMS WITH ANISODIAMETRIC PARTICLES,

Abstract

The behavior of soap lubricants and soap suspensions in hydrocarbon media in the presence of an applied electric field was investigated, with the effect produced by the electric field observed in polarized light. It was found that the application of an electric field up to 15 kv/cm produced a kind of flocculation in the suspension, viz: the suspended material became concentrated at one electrode and the suspension medium at the other electrode. Reversal of current direction produced a corresponding reversal of the effect. The applied electric field also produced some structural order in the suspension, and the ordering effect of the field was enhanced by the addition of surface-active agents such as a 50 percent solution of barium dialkyldithiophosphate in mineral oil. Photographs of the suspension in various stages of electrolysis are presented. A mechanism for the observed phenomena in terms of dipole ordering and dipole discharge by the applied field is proposed. It is concluded that further studies on the effect of electric fields applied to hydrocarbon media should prove interesting.
