Dynamic electrophoretic mobility of a spherical colloidal particle with a hydrodynamically slipping surface in an oscillating electric field

A theory of the dynamic electrophoresis of a spherical colloidal particle with a slip surface in an oscillating electric field is developed. The slipping length on the particle surface, which is the measure of the degree of the particle surface hydrophobicity, is introduced. The general expression of the particle electrophoretic mobility and its approximate analytic expressions for a particle carrying a low zeta potential are derived.
