In this work we investigate how combined data on dielectric dispersion and electrophoretic mobility of colloidal suspensions at different temperatures can be used to evaluate the two main quantities characterizing the solid/liquid interface, namely, the zeta potential and the stagnant layer conductivity (SLC). This is possible because the electric permittivity depends on the total surface conductivity, while the electrophoretic mobility is governed by both the zeta potential and that… CONTINUE READING
