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 ...

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.

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.

LCST polymers: Thermoresponsive nanostructured assemblies towards bioapplications
Polymer, 2020Abstract Thermoresponsive polymers constitute an important class of materials for biomedical application due to their thermally reversible coil-to-globule transition which can be exploited in a multitude of biomedical applications spanning from triggered drug delivery systems in the form of bulk hydrogels and nanoparticles, “smart” cell culture ...

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.

Poly(2-oxazoline) glycopolymers with tunable LCST behavior
Polymer Chemistry, 2011A series of thermo-responsive glyco-poly(2-oxazoline)s based on 2-ethyl-2-oxazoline and 2-(dec-9-enyl)-2-oxazoline were prepared. To study the effect of the sugar content on the solution behavior in water, two sets of copolymers with constant monomer-to-initiator ratios of 20 and 50 and varying amounts of the hydrophobic alkene functionalized monomer ...

“Isothermal” LCST transitions triggered by bioreduction of single polymer end-groups
Chem. Commun., 2013The α-termini of RAFT-derived thermoresponsive polymers were functionalised via thiol exchange with pyridyl disulfide. Addition of hydrophilic end-groups dramatically increased the observed cloud point of the polymers, without changing the composition of the main chain. Selective cleavage of the disulfide-linked end-groups was observed under conditions

Precise control of wettability from LCST tunable surface
Journal of Materials Chemistry, 2010In this study, we demonstrated precise control of wettability from a thermally-responsive surface and investigated the effects of chemical composition and surface roughness. By altering feeding manners of initiators during surface grafting process of poly(N-isopropylacrylamide-co-N-isopropylmethylacrylamide) [poly(NIPAAm-co-NIPMAM)], two thermally ...
