Tuning the lower critical solution temperature of thermoresponsive polymers by biospecific recognition

, 2011
A thermosensitive statistical copolymer based on oligo(ethylene glycol) methacrylates incorporating biotin was synthesized by free radical copolymerisation. The influence of added avidin on its thermoresponsive behaviour was investigated.

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

Gels, 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

Modulation of the lower critical solution temperature of thermoresponsive poly(N-vinylcaptrolactam) utlizing hydrophilic and hydrophobic monomers [PDF]

, 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.

Continuous refrigeration and dehumidification using the lower critical solution temperature cycle

Cell Reports Physical Science
Summary: Certain aqueous mixtures possess a lower critical solution temperature (LCST), such that when they are heated above the LCST, they separate into a water-rich and a water-scarce phase. This separation leads to a chemical potential difference once

Tunable Temperature Response of a Thermochromic Photonic Gel Sensor Containing N-Isopropylacrylamide and 4-Acryloyilmorpholine

Sensors, 2017
In this study, thermochromic photonic gels were fabricated using 2-hydroxyethyl methacrylate (HEMA) as a hydrogel building block, and 4-Acryloyl morpholine (ACMO) and N-isopropylacrylamide (NIPAAM) as thermoresponsive monomers with different critical ...

Lower critical solution temperature behavior in polymer blends: compressibility and directional-specific interactions [PDF]

Macromolecules, 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. Certain random copolymer-homopolymer blends are examples of the first possibility.
