Lower critical solution temperature (LCST) phase behaviour of an ionic liquid and its control by supramolecular host–guest interactions [PDF]

open access: yesChemical Communications, 2016
Lower critical solution temperature (LCST) phase behaviour of an imidazolium- based ionic liquid is reported, which can be controlled by concentration, the choice of cation, anion and solvent, and by supramolecular host–guest complex formation. Molecular

Tuning the Size of Thermoresponsive Poly(N-Isopropyl Acrylamide) Grafted Silica Microgels

open access: yesGels, 2017
Core-shell microgels were synthesized via a free radical emulsion polymerization of thermoresponsive poly-(N-isopropyl acrylamide), pNipam, on the surface of silica nanoparticles. Pure pNipam microgels have a lower critical solution temperature (LCST) of

LCST-type polymers based on chiral-polymeric ionic liquids [PDF]

open access: yes, 2014
The self-assembly of linear polymers containing chiral IL units generates a high-order supramacromolecular structure with a complex hierarchical architecture, which is able to exhibit thermoresponsive behavior (lower critical solution temperature: LCST ...

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

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

Thermal Conductivity of PNIPAm Hydrogels and Heat Management as Smart Windows

open access: yesMacromolecular Materials and Engineering, 2023
Though thermoresponsive lower critical solution temperature (LCST) hydrogels have attracted intense attention to be applied in smart windows, less efforts are paid on the LCST effect on the heat transfer process.

Recognition-mediated hydrogel swelling controlled by interaction with a negative thermoresponsive LCST polymer [PDF]

open access: yes, 2016
Most polymeric thermoresponsive hydrogels contract upon heating beyond the lower critical solution temperature (LCST) of the polymers used. Herein, we report a supramolecular hydrogel system that shows the opposite temperature dependence.

Tunable, Temperature-Responsive Polynorbornenes with Side Chains Based on an Elastin Peptide Sequence [PDF]

open access: yes, 2009
Random copolymers made by living ring-opening metathesis polymerization of norbornene monomers containing either the elastin peptide sequence -(VPGVG)- or pentaethylene glycol (see scheme; Mes=mesityl, pyr=pyridine) exhibit a lower critical solution ...

Role of Side-Chain Molecular Features in Tuning Lower Critical Solution Temperatures (LCSTs) of Oligoethylene Glycol Modified Polypeptides [PDF]

open access: yesThe Journal of Physical Chemistry B, 2016
A series of thermoresponsive polypeptides has been synthesized using a methodology that allowed facile adjustment of side-chain functional groups. The lower critical solution temperature (LCST) properties of these polymers in water were then evaluated relative to systematic molecular modifications in their side-chains.

Molecular Dynamics Calculations for the Temperature Response of Poly(alkylated tri(ethylene oxide)isocyanate) Aqueous Solution

open access: yesMacromol, 2023
Aqueous solutions of conventional temperature-responsive amphiphilic polymers undergo a coil–globule conformational transition around the lower critical solution temperature (LCST) that causes the polymer surfaces to become hydrophobic and the polymers ...
