Confinement-induced fluid-fluid phase transitions in simple fluid mixtures, under bulk supra-critical conditions
In a previous publication (Xie et al., Langmuir 29, 2659 (2013)), we demonstrated that polymer solutions, which display a bulk lower critical solution temperature (LCST) may undergo a phase transition in a porous environment below the LCST. Such capillary induced transitions are thus supra-critical, given that the associated bulk solution only contains a single fluid phase. The current work explor
