Contribution au Phenomene de Mouillabilite en presence Dun tensioactif anionique SDS et non ionique C11E5

Abstract

The experimental survey of the water drops to different concentrations from non ionic surfactant (C11E5) and set down anionic (SDS) on glass horizontal surfaces has been made. The 1st step consisted in measuring the tension of surface, the 2nd allowed us to determine the influence of these surfactants on the physical parameters of wetting (contact angle ...).The numeric simulation of the equation of profile of the drop allowed us to validate the empirical results found.
