  • Title: Electrophoretic mobility of a charged spherical colloidal particle covered with an uncharged polymer layer.
    Author: Ohshima H.
    Journal: Electrophoresis; 2002 Jul; 23(13):1995-2000. PubMed ID: 12210250.
    Abstract:
    A general expression is derived for the electrophoretic mobility of a spherical charged colloidal particle covered with an uncharged polymer layer in an electrolyte solution in an applied electric field for the case where the particle zeta potential is low. It is assumed that electrolyte ions as well as water molecules can penetrate the polymer layer. Approximate analytic expressions for the electrophoretic mobility of particles carrying low zeta potentials are derived for the two extreme cases in which the particle radius is very large or very small.
