Abstract
|
We have developed an analytic self-consistent field theory of the effective interactions between nano- colloids mediated by irreversibly adsorbing polymers and non-adsorbing polymers having a gyration radius much larger than that of colloids. By making use of this theory, we have calculated the potential of the polymer-mediated forces for the above cases of polymer adsorption. On the basis of the obtained results for the polymer-mediated potentials, we have obtained the stability ratio and rate of the coagulation in the presence of adsorbing and non-adsorbing polymers. As a final result of our studies, we constructed the coagulation diagram that quantifies the combined effect of the Van der Waals and polymer-mediated forces on the rate of colloid coagulation. Kinetic stability of the material-specific colloid systems is discussed. POLYM. COMPOS., 2013. © 2013 Society of Plastics Engineers
