Thermoresponsive Polymers for Biomedical Applications [PDF]
Polymers, 2011 Thermoresponsive polymers are a class of “smart” materials that have the ability to respond to a change in temperature; a property that makes them useful materials in a wide range of applications and consequently attracts much scientific interest.

Thermoresponsive Gelatin Nanogels
ACS Macro Letters, 2014We present a novel tunable thermoresponsive gelatin nanogel that shows a volume transition at ∼32 °C. A thermally induced volume reduction of more than 30× is observed due to the helix to random coil transition of gelatin chains confined in the nanogels. The physical process and key factors influencing thermoresponsive properties are investigated using

We demonstrate herein that corannulene, a bowl‐shaped polycyclic aromatic hydrocarbon, can assemble into larger supramolecular structures in water through a change in the solution temperature. This property is invoked through a simple five‐fold symmetric substitution of the corannulene nucleus with triethylene glycol units.

Backbone-Thermoresponsive Hyperbranched Polyethers
Journal of the American Chemical Society, 2006A new type of materials, the backbone-thermoresponsive hyperbranched polyether, was successfully synthesized by proton-transfer polymerization of 1,4-butanediol diglycidyl ether and various triols, and the lower critical solution temperature (LCST) values can be readily adjusted from 19.0 to 40.3 degrees C by changing the hydrophilic/hydrophobic ...

Thermoresponsive Supramolecular Dendronized Polymers
Chemistry – An Asian Journal, 2011AbstractCombining the concepts of supramolecular polymers and dendronized polymers provides the opportunity to create bulky polymers with easy structural modification and tunable properties. In the present work, a novel class of side‐chain supramolecular dendronized polymethacrylates is prepared through the host–guest interaction.
