In order to study the effects of penetrability in mixtures of dissimilar particles we consider hard colloidal spheres and penetrable spheres modelling coils. Polymers and colloids interact by means of a repulsive step-function pair potential, which allows for insertion of colloids into the polymer coil. We find a significant stabilization of the mixed phase for large polymer-to-colloid size ratio. [more]  Read the [full paper] as pdf. |
Colloid-polymer mixtures: Beyond the AOV model
Extensions include taking into account an explicit solvent of point particles [27], penetrability of (small) colloids into polymers [28], colloid-induced polymer compression [31], the influence of polymer interactions on fluid-demixing [34] and on the contact angle of the colloidal liquid-gas interface and a hard wall [50], as well as the stability of the floating liquid phase in sedimenting colloid-polymer mixtures for non-ideal polymers [52].[more]
