Abstract
Several electrooptic parameters can be used to follow the stages of polyelectrolyte adsorption on colloid particle surfaces. The process of electrostatic stabilization, achieved by polyelectrolyte surface recharging, is investigated for a series of samples and the results are compared to those obtained for low molecular surfactant stabilization. The results indicate a significant decrease of the relaxation frequency of particle electric polarizability in the presence of polyelectrolyte coverage. Evidence is given for the direct relation of the electrooptic relaxation frequency to the type of the adsorbed polymer molecule.
