Charge-Determined LCST/UCST Behavior in Ionic Polypeptoids

Biomacromolecules, 2018
Stimuli-responsive polymers have received increasing interest for a variety of applications. Here, we report a series of unique charge-determined thermoresponsive polypeptoids synthesized by a combination of ring-opening polymerization and click chemistry.

A Novel Nanocomposite Hydrogel with Precisely Tunable UCST and LCST

Macromolecular Rapid Communications, 2015
Novel thermosensitive nanocomposite (NC) hydrogels consisting of organic/inorganic networks are prepared via in situ free radical polymerization of 2‐(2‐methoxyethoxy) ethyl methacrylate (MEO2MA) and oligo(ethylene glycol) methacrylate (OEGMA) in the presence of inorganic cross‐linker clay in aqueous solution.

Tunable LCST/UCST-Type Polypeptoids and Their Structure–Property Relationship

Biomacromolecules, 2020
Bioinspired thermoresponsive polymeric materials with tunable phase-transition behaviors are highly desirable for biomedical applications. Here, we reported a facile approach for the synthesis of both lower critical solution temperature (LCST) and upper critical solution temperature (UCST) types of thermoresponsive polypeptoids with tunable phase ...

Effects of polyelectrolyte complexation on the UCST of zwitterionic polymer

Polymer, 2000
Abstract A zwitterionic polymer—poly-3-dimethyl(methacryloyloxyethyl)ammonium propane sulfonate (PDMAPS)—was synthesized and its complexation behaviors with polyanion: poly-2-acrylamido-2-methyl propane sulfonic acid (PAMPS); and polycation: poly-3-acryloylamino propyl trimethyl ammonium chloride (PDMAPAA-Q); or: x , y -ionene bromides ( x =3,6; y =

Electrostatic Interaction-Induced Clusteroluminescence of Polyelectrolyte with UCST Behavior

Langmuir
Polymers composed of zwitterionic monomer units generally exhibit upper critical solution temperature (UCST)-type thermoresponsive behavior. However, these monomers possess specialized structures, involve complex synthesis, and have limited varieties available.

Anomalous Thermal Conductivity in the Close Neighbourhood of a UCST

Berichte der Bunsengesellschaft für physikalische Chemie, 1990
AbstractResults of measurements of the temperature dependence of the thermal conductivity of the binary system perfluoromethylcyclohexane + methylcyclohexane are reported. These were obtained using a modified hot‐wire transient technique which allowed measurements to be made using very small temperature rises (<100 mK), with a precision of better ...

Synthesis of Thermo‐Responsive Polymers With Both Tunable UCST and LCST

Macromolecular Rapid Communications, 2011
AbstractNew water‐soluble block copolymers of 2‐(2‐methoxyethoxy)ethyl methacrylate (MEO2MA), oligo(ethylene glycol) methacrylate (OEGMA), and N‐(3‐(dimethylamino) propyl) methacrylamide (DMAPMA) (poly(OEGMA‐co‐MEO2MA)‐b‐poly(DMAPMA)) were prepared via sequential reversible addition‐fragmentation chain transfer (RAFT) polymerization.
