Atomistic Molecular Dynamics Simulations of the Lower Critical Solution Temperature Transition of Poly(N‑vinylcaprolactam) in Aqueous Solutions

, 2019
Poly­(N-vinylcaprolactam) (PVCL) is a thermo-responsive polymer, which exhibits a lower critical solution temperature (LCST) in an aqueous solution. The LCST of this hydrophilic-to-hydrophobic transition is found to be strongly dependent on the salt-type

Chiral recognition of macromolecules with cyclodextrins: pH- and thermosensitive copolymers from N-isopropylacrylamide and N-acryloyl-D/L-phenylalanine and their inclusion complexes with cyclodextrins

Beilstein Journal of Organic Chemistry, 2011
In the present work we report the enantioselective recognition of water soluble stimuli-responsive polymers bearing phenylalanine moieties via host-guest interaction with β-cyclodextrin and randomly-methylated-β-cyclodextrin (RAMEB-CD).

Controlling Linear and Non‐Linear Mechanics in Multicomponent Hydrogels Through Programmable Supramolecular and Covalent Interactions

Journal of Polymer Science, EarlyView.
Fully synthetic, multi‐component hydrogels are engineered that possess tunable (non)‐linear mechanics by programmable supramolecular and covalent interactions. By changing the type of inter‐network interaction, the linear and non‐linear mechanics of the macroscopic hydrogel were programmed.

Lower Critical Solution Temperature Behavior in Polymer Blends:Compressibility and Directional-Specific Interactions [PDF]

, 1984
Lower critical solution temperature (LCST) behavior in polymer blends is shown to be the result of the compressible nature of the system, the directional-specific character of the intermolecular interactions, or a combination of both.

Lower critical solution temperature sensitivity to structural changes in poly(N-isopropyl acrylamide) homopolymers

, 2019
The effect of the molecular weight on the lower critical solution temperature (LCST) has been discussed extensively, where LCST increased with molar mass, decreased or kept constant, which leads to confusion.

Interface‐Directed Self‐Assembly of Thermoresponsive Block Copolymers for Tunable Interfacial Nanostructures

Small, EarlyView.
Surface pressure and temperature direct the assembly of P(NIPAM‐b‐AEMA) at the air‐water interface, transforming continuous films into tunable micellar nanodomains. The thermoresponsive P(NIPAM) block enables temperature‐controlled changes in domain size and order.

Polymer Fractionation at a Lower Critical Solution Temperature Phase Boundary

, 1967
The influence of pressure on a lower critical solution temperature is much more pronounced than on an upper critical solution temperature. Accordingly it is possible to control phase separation at a LCST phase boundary under isothermal conditions by ...

Multi‐Scale 3D Printing of Magnetic Polymer Nanocomposites with Controlled Particle Dispersion and Hyperthermic Response

Small, EarlyView.
Dispersion of magnetic nanoflowers in trimethylolpropane ethoxylate triacrylate to generate photocurable nanocomposites is described. Particle dispersion provides processability and target AC‐field stimulated temperature increases. Complex (DLP) printed structures with submicron features are demonstrated, and the potential for stimulated release of ...

Supramolecular Mechanophore Additives Enable Mechanochromic Hydrogels

Angewandte Chemie, Volume 138, Issue 44, 26 October 2026.
A supramolecular loop‐forming mechanophore featuring a quencher and an emitter is incorporated as a water‐soluble macromolecular additive into hydrogels. In the stress‐free state, intramolecular charge‐transfer interactions fold the loop and quench fluorescence.
