✦ Synopsis

Varoqui's theory [Nouv. J. Chim. 6, 187 (1982)] for the electrophoretic mobility of a charged colloidal particle adsorbed by neutral polymers with an exponential distribution of the polymer segments is extended to the case where adsorbed polymers are charged. An analytic mobility expression is derived on the basis of the linearized Poisson-Boltzmann equation. Comparison is made with the case of particles coated with a polyelectrolyte layer of fixed thickness with uniform segment distribution.

The electrophoretic mobility of a particle coated with an ionpenetrable charged membrane in a uniform electric field is investigated. In particular, the effects of the distribution of fixed charges and that of the dielectric constant in the membrane phase on the electrophoretic mobility are investig
