DIELECTRIC AND ELECTROPHORETIC RESPONSE OF ELECTROCHEMICAL DOUBLE LAYER.

The authors analyze the problem of a charged sphere in an electrolytic solution under the excitation of an electric field. The system displays dielectric dispersion with dielectric enhancement as much as 3,000 at low frequency for a zeta potential of 100 mv and a volume fraction of 30%. The system also displays electro-osmotic effect if the spheres are held fixed and it displays electrophoretic effect if they are freely suspended in an electrolyte.
