Modulation of the Lower Critical Solution Temperature of Thermoresponsive Poly(N-Vinylcaprolactam) Utilizing Hydrophilic and Hydrophobic Monomers

open access: yesPolymers, 2023
 Four-dimensional printing is primarily based on the concept of 3D printing technology. However, it requires additional stimulus and stimulus-responsive materials. Poly-N-vinylcaprolactam is a temperature-sensitive polymer. Unique characteristics of poly-

RNAs undergo phase transitions with lower critical solution temperatures

Nature Chemistry, 2022
Abstract Co-phase separation of RNAs and RNA-binding proteins is thought to drive the biogenesis of ribonucleoprotein granules. RNAs can also undergo phase transitions in the absence of proteins. However, the physicochemical driving forces of protein-free, RNA-driven phase transitions remain unclear.

Dynamical heterogeneity in the gelation process of a polymer solution with a lower critical solution temperature

Soft Matter, 2021
The gelation of a hydrophobically modified hyaluronic acid aqueous solution which shows a lower critical solution temperature of about 25 °C was investigated by multi-particle tracking microrheology.

Tuning Critical Solution Temperature for CO2 Capture by Aqueous Solution of Amine

open access: yesJournal of Molecular Liquids, 2021
International audienceAqueous solution of amine is a mature technology to selectively absorb CO2 from an industrial exhaust. Monoethanolamine (MEA) is still considered as the reference amine and unfortunately, the energy necessary to desorb CO2 and ...

Lower and Upper Critical Solution Temperatures of Binary Polymeric Solutions

Fluid Phase Equilibria, 2016
Abstract The phase behavior of binary polymeric solutions such as lower and upper critical solution temperatures has an important role in many polymeric processes. For theoretical investigation on the prediction of these temperatures, a substantial number of data points on binary polymeric solutions were collected from literature and used to present ...

Upper and Lower Critical Solution Temperatures in Polystyrene Solutions. II

Macromolecules, 1973
Abstract Upper and lower critical solution temperatures have been determined for solutions of polyethylene in n-butyl acetate and n-amyl acetate over the molecular weight range of M η = 1·36 × 10 4 to 17·5 × 10 4 . Polyethylene solution in n-butyl acetate displays a smaller miscibility region than that of the polyethylene/n-amyl acetate system,

A comparison of lower critical solution temperatures of some polymer solutions

Polymer, 1967
Abstract The Lower Critical Solution Temperature (LCST) in polymer solutions is discussed in terms of the Prigogine solution theory which predicts an LCST below the vapour-liquid critical temperature of the solvent (T c ). The interval between these two temperatures depends on differences in chain length and ‘flexibility’ of the polymer and solvent ...

Thermoresponsive dendronized polymers with tunable lower critical solution temperatures

Chemical Communications, 2008
A series of first (PG 1) and second generation (PG 2) dendronized polymers were synthesized which exhibit fast and sharp phase transitions with negligible hystereses in aqueous solutions and apparent lower critical solution temperatures (LCSTs) in the range of 33-49 degrees C.
