Investigation of Lyophobic Colloids by Electrophoretic Light Scattering Method

The main property of lyophobic colloids is the insolubility or very low solubility of a substance of the dispersed phase in a dispersion medium. The presence of surfactants in the colloid makes it more stable, as it prevents adhesion and settling of nanoparticles. This makes such colloids more attractive for use in various fields of application from electronics to medicine. This article describes the study of lyophobic sols represented by magnetic fluids, gold and copper nanoparticles by electrophoretic light scattering. Such parameters of colloids as electrophoretic mobility and zeta potential were studied, which are important for identifying the features of the binding ability, for assessing the stability of the solution. The results of an experimental study are presented.
