  • Title: Wetting reversal in colloid-polymer systems.
    Author: Blokhuis EM, Kuipers J.
    Journal: Phys Rev E Stat Nonlin Soft Matter Phys; 2010 May; 81(5 Pt 1):051602. PubMed ID: 20866234.
    Abstract:
    The wetting of a phase-separated colloid-polymer mixture in contact with a hard wall is analyzed using free volume theory in a Nakanishi-Fisher-type approach. We present results for the wetting phase diagram for several model approximations. Our analysis is compared with a previous analysis by Aarts [J. Chem. Phys. 120, 1973 (2004)]. We find that there is a crossover from wetting to drying at a threshold value for the colloid-polymer size ratio and that the transitions are close to the critical point and of second order in nature.
