Abstract
A theory is presented for the rheology of dense, electrically stabilized, colloidal suspensions under shear. It is based on a combination of an activation model (microsocopic scale) and a Landau theory (mesoscopic scale). Shear thickening is described here as a structural transition induced by an electroviscous effect in concentrated suspensions. A set of phenomenological equations are established that describe the shear-rate dependent viscosity. The results will be compared to experimental investigations on monodisperse and polydisperse suspensions of different volume fractions. A good agreement between theory and experimental results can be obtained.
