The LCST phase-transition of aqueous PNIPA solutions in rising concentrations of the strong chaotropic salt KSCN was studied microcalorimetrically by DSC and apparently for the first time by ITC. An endothermic (entropy driven) binding of KSCN onto PNIPA was observed, explained by electrostatic perturbation of hydrophobic hydration by adsorbed ions.

Journal of Applied Physics, 2018
We proposed a thermoresponsive light scattering device that utilizes the surface behavior between polyimide and an ionic liquid-water mixture exhibiting lower critical solution temperature (LCST)-type phase separation. The LCST behavior for an ionic liquid device utilizing the polyimide with and without alkyl side chains was investigated.

The triblock copolymer, 2-nonyl-2-oxazoline-2-ethyl-2-oxazoline-2-methyl-2-oxazoline triblock copolymer, forms micelles in water/BMIM-PF6 ionic liq. systems. The micelles exhibit thermoreversible phase transfer behavior and may offer a simple means to transport chems. back and forth between two immiscible phases. [on SciFinder (R)]
