Upper critical solution temperature behavior of poly(N-isopropylacrylamide) in an ionic liquid and preparation of thermo-sensitive nonvolatile gels
Poly(N-isopropylacrylamide) and its gels exhibited upper critical solution temperature behavior in a hydrophobic ionic liquid, 1-ethyl-3-methylimidazolium bis(trifluoromethane sulfone)imide, which may be utilized to prepare stimuli-sensitive polymer systems without the problem of solvent evaporation.
