Criticality and phase separation in a two-dimensional binary colloidal fluid induced by the solvent critical behavior
journal contribution
posted on 2013-07-03, 14:09 authored by O. Zvyagolskaya, Andrew ArcherAndrew Archer, C. BechingerWe present an experimental and theoretical study of the phase behavior of a binary
mixture of colloids with opposite adsorption preferences in a critical solvent. As a result of the
attractive and repulsive critical Casimir forces, the critical fluctuations of the solvent lead to
a further critical point in the colloidal system, i.e. to a critical colloidal-liquid–colloidal-liquid
demixing phase transition which is controlled by the solvent temperature. Our experimental
findings are in good agreement with calculations based on a simple approximation for the free
energy of the system.
