Abstract
The main focus of the zeta potential analysis is information on the surface charge. This charge, which is established on the surface of a solid material in contact with water, determines the behavior of the material in processes where aqueous systems play a role. Electrostatic attraction and repulsion are driven by the surface charge (among other things) and thus by the solid surface zeta potential. Furthermore, the zeta potential provides information about surface functionality, the specific interactions of dissolved compounds with the solid surface and liquid-on-solid surface adsorption processes.
The seminar will cover the theory and practical aspects of the measurements of streaming potential and electrophoretic mobility. The applications of the zeta potential analyses will focus on the characterization of polymer membranes for water treatment, biomaterials and medical devices, semiconductors, and cosmetic formulations.
