Surface charge reversal and hydration forces explained by ionic dispersion forces and surface hydration
The first direct measurements of forces between mica surfaces in electrolytes showed an apparent short range repulsion additional to the predictions of DLVO theory. The origins of such " secondary hydration forces" have remained a mystery. We show they can be explained as an repulsive entropic force appearing due to a hydration surface layer with longer range secondary hydration forces appearing as a consequence of ionic dispersion forces. Ionic dispersion forces are calculated from dynamic...[Show more]
