Molecular dynamics simulations evidence the thermoresponsive behavior of PNIPAM and PDEA in glycerol solutions

Frontiers in Nanotechnology, 2023
Polymers exhibiting thermoresponsive behavior above a lower critical solution temperature (LCST) undergo a coil-to-globule phase transition that has many biomedical applications, including biosensing, the control of release devices, and gene or drug ...

Lower Critical Solution Temperatures of Polybutadiene Solutions

, 1968
The lower critical solution temperature (LCST) is observed in polymer solvent systems as a rather high temperature above which the solution separates into two phases. This is a relatively recently discovered phenomenon, since it normally occurs above the

Modeling lower critical solution temperature behavior of associating polymer brushes with classical density functional theory [PDF]

, 2013
We study the lower critical solution temperature (LCST) behavior of associating polymer brushes (i.e., poly(N-isopropylacrylamide)) using classical density functional theory.

Cation-Induced Hydration Effects Cause Lower Critical Solution Temperature Behavior in Protein Solutions

, 2016
The phase behavior of protein solutions is important for numerous phenomena in biology and soft matter. We report a lower critical solution temperature (LCST) phase behavior of aqueous solutions of a globular protein induced by multivalent metal ions ...

Scaled water sigma potential as a descriptor of LCST and UCST behavior in aqueous ionic liquid solutions

Journal of Ionic Liquids
This study introduces the scaled sigma potential of water (σr), a new metric using the COSMO-RS (Conductor like Screening Model for Real Solvents) framework, as a descriptor of upper and lower critical solution temperature (UCST and LCST) governed phase ...

Thermodynamic Limits to Molecular Doping in Conjugated Polymers: A Perspective on Phase Behavior and Miscibility

Advanced Materials, EarlyView.
Molecular doping of conjugated polymers is fundamentally constrained by thermodynamic phase behavior. This Perspective reframes doping efficiency and stability in terms of miscibility limits, binodals, and solvus boundaries, highlighting the role of effective interaction parameters and charge transfer.
