Seminarraum A1-A3, Building 04.6

Salt-free suspensions are just composed of charged colloidal particles and the added counterions released by the particles to the solution, that counterbalance their surface charge. By using a cell model approach, we analyze the influence of nite ion size eects in the response of a salt-free concentrated suspension of spherical particles to static and oscillating electric fields.
We study the equilibrium electric double layer, the static and dynamic electrophoretic mobility of the particles, and the conductivity and the dielectric response of the suspension.
