Part of the Progress in Colloid & Polymer Science book series (PROGCOLLOID, volume 76)


The behavior of dilute clay colloids/cationic copolymers systems is investigated as a function of the ionic strength I of the medium for various charge levels of the polyelectrolyte chain. Changing I not only has an inflauence on the interaction between the surface and the electrostatically bound segments but can also more or less affect the copolymer conformation according to its ionicity degree. The dependence of adsorption and flocculation processes on the ionic strength can be explained through these both effects.
