Abstract
A theory of electrophoresis of a colloidal particle coated with a polyelectrolyte layer [H. Ohshima, J. Colloid Interface Sci., 163 (1994) 474] is extended to cover the case where a polyelectrolyte layer is not fully ion-penetrable. Partition coefficients b of the electrolyte ions into the polyelectrolyte layer are introduced. For the extreme case of b = 0, where the polyelectrolyte layer is not ion-penetrable at all so that the ionic shielding effects in the polyelectrolyte layer disappears, the mobility exhibits a significant dependence on the polyelectrolyte layer thickness. This is in contrast to the opposite extreme case of fully ion-penetrable polyelectrolyte layers (b = 1), where the dependence of the mobility on the polyelectrolyte layer thickness is quite small for most cases.
