摘要

The colloidal stability of polystyrene particles with different surface functional groups (sulfate and carboxyl) has been studied after adsorption of Triton X-100. The coverage degree and the medium pH were the main factors in this study. Three different types of colloidal stabilization were found, which can be clasified as a function of the relationship between the atractive interaction energy (V_A, Van der Waals type) and the steric interaction energy (V_S, repulsive type): electrostatic (V_S valence 0), electrosteric (V_S<|V_A|), and steric (V_S>|V_A|). The main difference between these stabilization types is the response against the electrolyte concentration: the first and second cases are affected by electrolyte addition, while the third one does not.
