Modélisation des Interactions Electrostatiques dans les Dispersions Colloïdales.

Abstract

This work is carried out in the context of research for modeling the electrostatic interactions in colloidal suspensions using the DLVO theory. This later reduces the multicomponent colloidal system to an effective one formed by colloidal particles dressed by their ionic clouds, knows as electric double layer (EDL). The electrostatic interactions resulting from the superposition of the EDL represent the electrostatic contribution of the DLVO potential. This later is calculated by solving the Poisson Boltzmann equation in the fromwork of the renormalized cell-model in the case of non linear phenomena.
