Tunable LCST/UCST-Type Polypeptoids and Their Structure–Property Relationship
Biomacromolecules, 2020Bioinspired 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 ...

Tailoring the LCST of Thermosensitive Hydrogel Thin Films Deposited by iCVD
Langmuir, 2014Using the iCVD (initiated chemical vapor deposition) polymerization technique, we generated a library of thermosensitive thin film hydrogels in the physiological temperature range. The library shows how a specific hydrogel with a desired temperature response can be synthesized via the copolymerization of three main components: (a) the main ...

Thermo‐responsive albumin hydrogels with LCST near the physiological temperature
Journal of Applied Polymer Science, 2011AbstractThis paper deals with the synthesis of thermoresponsive microspheres with proteic structure exhibiting a transition temperature close to the body temperature. The hydrogels were synthesized by free radical polymerization of methacrylate Bovine Serum Albumin (BSA‐MA) as crosslinker, and 2‐hydroxyethyl methacrylate (HEMA) and/or N ...

Modeling and Elucidating the Behavior of a Thermoresponsive LCST Ionic Liquid
Journal of Chemical Information and ModelingDesalination of seawater by forward osmosis is a technology potentially able to address the global water scarcity problem. The major challenge limiting its widespread practical application is the design of a draw solute that can be separated from water by an energetically efficient process and then reused for the next cycle.

A Self-Oscillating Polymer Chain with High LCST
Advanced Materials Research, 2014A novel self-oscillating polymer displaying a high lower critical solution temperature (LCST) was developed. The novel polymer chain underwent soluble-insoluble self-oscillation induced by a Belousov–Zhabotinsky reaction. The driving force of the self-oscillation was the differing solubility of the polymer chain in the reduced and oxidized states.

Synthesis of Thermo‐Responsive Polymers With Both Tunable UCST and LCST
Macromolecular Rapid Communications, 2011AbstractNew 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.

Gluonic and regulatory solvents and another type of LCST-transition
The Journal of Chemical PhysicsPolymers in multicomponent solvents are key to understanding biomolecular condensates and promising systems for the preparation of polymer materials for achieving multi-stimuli-responsive properties. Examples of novel transition scenarios in multicomponent solvents are co-nonsolvency and the phase separation of water-soluble biomacromolecules, such as ...

Effect of order on LCST and gelation of polyolefin solutions
1982Lower critical solubility temperatures (LCST) have been measured for polyethylene (PE), polypropylene, ethylene-propylene copolymers, polybutene-1, polypentene-1 and poly 4-methylpentene-1 (P4MP1) in twenty-five isomeric alkanes. The LCST for PE are much lower than for branched polyolefins, especially in branched alkanes.
