Electrophoretic mobility of silica particles in a mixture of toluene and ethanol at different particle concentrations

Résumé

In this paper we present measurements of the electrophoretic mobility of colloidal particles by using heterodyne detection of light scattering. The measurements have been done up to concentrations of 5.4 % of silica nanoparticles, with a diameter of the order of 80 nm, in a mixture of 70 % toluene and 30 % ethanol. In order to make possible the measurements at these concentrations the liquid mixture is chosen as to match the index of refraction of the particles, thus resulting in a transparent suspension.
