Effects of slit-like pore confinement on the closed loop immiscibility in symmetric binary model mixtures: fundamental measure density functional approach

Abstract

We investigate the adsorption of model symmetric binary mixtures, exhibiting closed loop immiscibility in the bulk phase, in slit-like pores by using a density functional approach. Our focus is on changes in the closed loop phase diagram owing to Confinement. We have found that, in general, confinement narrows immiscibility loops in the temperature-selectivity plane.
