Phase diagram for a mixture of colloids and polymers with equal size
Phase diagram for a mixture of colloids and polymers with equal size
We present the phase diagram of a colloid-polymer mixture in which the radius a of the colloidal spheres is approximately the same as the radius R of a polymer coil (q = R/a approximate to 1). A three-phase coexistence region is experimentally observed, previously only reported for colloid-polymer m...

We present the phase diagram of a colloid-polymer mixture in which the radius a of the colloidal spheres is approximately the same as the radius R of a polymer coil (q = R/a approximate to 1). A three-phase coexistence region is experimentally observed, previously only reported for colloid-polymer mixtures with smaller polymer chains (q less than or similar to 0.6). A recently developed generalized free-volume theory (GFVT) for mixtures of hard spheres and non-adsorbing excluded-volume polymer chains gives a quantitative description of the phase diagram. Monte Carlo simulations also agree well with experiment. Copyright (C) EPLA, 2008. |
