  • Title: Influence of polymer-excluded volume on the phase-behavior of colloid-polymer mixtures.
    Author: Bolhuis PG, Louis AA, Hansen JP.
    Journal: Phys Rev Lett; 2002 Sep 16; 89(12):128302. PubMed ID: 12225127.
    Abstract:
    We determine the depletion-induced phase-behavior of hard-sphere colloids and interacting polymers by large-scale Monte Carlo simulations using very accurate coarse-graining techniques. A comparison with standard Asakura-Oosawa model theories and simulations shows that including excluded-volume interactions between polymers leads to qualitative differences in the phase diagrams. These effects become increasingly important for larger relative polymer size. Our simulation results agree quantitatively with recent experiments.
