Thermodynamic Description of the LCST of Charged Thermoresponsive Copolymers [PDF]

Macromolecules, 2014
The dependence of the lower critical solution temperature (LCST) of charged, thermosensitive copolymers on their charge fraction and the salt concentration is investigated by employing systematic cloud-point experiments and analytical theory. The latter is based on the concept of the Donnan equilibrium incorporated into a thermodynamic expansion of a ...

Tailoring a UCST-LCST-pH Multiresponsive Window through a Single Polymer Complex of Chitosan–Hyaluronic Acid

, 2022
Multistimuli-responsive polymers are important for controlled release. Owing to the fact that these polymers are derived from vinyl-based monomers, their decoration with other molecules is limited. Polysaccharides, especially chitosan (CS) and hyaluronic

Driving Forces of UCST and LCST Liquid-Liquid Phase Separations. [PDF]

ACS Omega
Abstract A liquid mixture of two or more components can phase separate into two liquid phases by changing the temperature. Ordinary chemical perception would attribute this transition to a competition between the favorable enthalpy of the biphasic state and the favorable entropy of the (mixed) monophasic state, rationalizing the ...

Heat storage for the coupling of Waste Heat Recovery and hydrogen production in a Solid-Oxide electrolyser [PDF]

MATEC Web of Conferences
The dihydrogen molecule H2 is set to play a major role in future energy systems, both as a component of fuels or synthesis gases, and as an energy carrier for long-term electricity storage.

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

Kinetics of Water Transfer Between the LCST and UCST Thermoresponsive Blocks in Diblock Copolymer Thin Films Monitored by In Situ Neutron Reflectivity

Advanced Materials Interfaces, 2023
The kinetics of water transfer between the lower critical solution temperature (LCST) and upper critical solution temperature (UCST) thermoresponsive blocks in about 10 nm thin films of a diblock copolymer is monitored by in situ neutron reflectivity ...
