Electrokinetic Properties and Conductance Relaxation of Polystyrene and Silver Iodide Plugs

“This thesis describes an experimental study on the electrokinetic and electrical properties of concentrated polystyrene and silver iodide dispersions. The purpose of the study is to obtain information on the structure of the electrical double layer at the solid-liquid interface. Special attention is paid to the various
polarization phenomena that may interfere in electrokinetic and conductance measurements on condensed systems. After a general introduction in chapter 1, in chapter 2 we discuss the preparation and characterization of the polystyrene latices. The geometry of these colloids is well-defined and easy to
control, their surface properties, on the contrary, are not. The number and nature of the surface groups may change upon characterization, due to contact with a solution of high ionic strength as well as during storage. In order to preclude any effect of these phenomena on the electrokinetic experiments, after preparation the latices have been treated in a special way.”
