Reactive thermoresponsive copolymer scaffolds

Chemical Communications, 2010
Thermoresponsive copolymer scaffolds containing reactive aldehyde functions were prepared and a selection of organic residues conjugated to these copolymer scaffolds through oxime/hydrazone formation. The conjugation of hydrophobic residues affords copolymers whose lower solution critical temperatures are in most cases higher than that of the parent ...

Thermoresponsive Poly(2‐oxazine)s

Macromolecular Rapid Communications, 2011
AbstractThe monomers 2‐methyl‐2‐oxazine (MeOZI), 2‐ethyl‐2‐oxazine (EtOZI), and 2‐n‐propyl‐2‐oxazine (nPropOZI) were synthesized and polymerized via the living cationic ring‐opening polymerization (CROP) under microwave‐assisted conditions. pEtOZI and pnPropOZI were found to be thermoresponsive, exhibiting LCST behavior in water and their cloud point ...

Thermoresponsive Dendronized Polymers

Macromolecules, 2008
The efficient synthesis of high molar mass, first- (G1) and second-generation (G2) dendronized polymethacrylate derivatives PG1 and PG2, respectively, and their thermoresponsive properties in aqueous solution are described. All dendrons are branched 3-fold and were synthesized on the multigram scale using gallic acid as branching point and tri(ethylene

Thermoresponsive Photonic Crystals

The Journal of Physical Chemistry B, 2000
Hydrogel nanoparticles that undergo volume phase transitions in response to changes in temperature and pH have been used to assemble colloidal crystal gels with environmentally tunable optical properties. When monodisperse, ∼210-nm-diameter hydrogel particles are close-packed via centrifugation, the resultant viscous polymer pellet displays a bright ...

Thermoresponsive Hydrogels for Cellular Delivery

Therapeutic Delivery, 2012
The delivery of living cells into a host body has emerged as a promising approach to treating a variety of different diseases and for tissue repair. However, one of the major obstacles for clinical success is to deliver the cells to the target tissue without losing control of cell fate and function after transplantation.

New directions in thermoresponsive polymers

Chemical Society Reviews, 2013
Interest in thermoresponsive polymers has steadily grown over many decades, and a great deal of work has been dedicated to developing temperature sensitive macromolecules that can be crafted into new smart materials. However, the overwhelming majority of previously reported temperature-responsive polymers are based on poly(N-isopropylacrylamide ...

Thermoresponsive Polymeric Nanoemulsions

Macromolecular Rapid Communications, 2006
AbstractSummary:Solutions of poly(N‐isopropylacrylamide) (PNIPA) with added sodium dodecyl sulfate (SDS) were investigated by light scattering methods at temperatures of 15–40 °C. The formation of well‐defined nanoparticles of PNIPA was observed on heating at low SDS additions.

Thermoresponsive polymer-stabilized silver nanoparticles

Journal of Colloid and Interface Science, 2008
Silver nanoparticles (Ag NPs) stabilized by a thermoresponsive polymer, poly(N-isopropylacrylamide) (PNIPAM), have been synthesized by the reduction of silver ions with NaBH(4) in aqueous solutions. The obtained Ag NPs are very stable at room temperature due to the extended coil conformation of the PNIPAM chain at temperatures below its volume phase ...
