End-group functionalization of poly(2-oxazoline)s using methyl bromoacetate as initiator followed by direct amidation [PDF]

open access: yes, 2019
Poly(2-alkyl/aryl-2-oxazoline)s (PAOx) are an alluring class of polymers for many applications due to the broad chemical diversity that is accessible for these polymers by simply changing the initiator, terminating agent and the monomer(s) used in their ...

Novel thermoresponsive assemblies of co-grafted natural and synthetic polymers for water purification [PDF]

open access: yes, 2016
Water contamination and its purification are a global problem. The current approach to purify water is reduction of impurities to acceptable levels. One of the ways to achieve this is by use of water-soluble polymers that extract organic and metallic ...

Differences in pressure and temperature transitions of proteins and polymer gels

open access: yesBrazilian Journal of Medical and Biological Research, 2005
Pressure-driven and temperature-driven transitions of two thermoresponsive polymers, poly(N-isopropylacrylamide) (pNIPAM) and poly(N-vinylisobutyramide) (pNVIBA)), in both a soluble linear polymer form and a cross-linked hydro-gel form, were examined by ...

Thermoresponsive, stretchable, biodegradable and biocompatible poly(glycerol sebacate)-based polyurethane hydrogels [PDF]

open access: yes, 2015
Thermoresponsive, stretchable, biodegradable and biocompatible polyester-based polyurethane (PEU) hydrogels, based on poly(glycerol sebacate) pre-polymer and poly(ethylene glycol)s of different molecular masses were synthesized by a facile solvent-based ...

Effect of surfactant concentration on the responsiveness of a thermoresponsive copolymer/surfactant mixture with potential application on Smart foams formulations

open access: yes, 2017
We studied a system formed by a mixture of a thermoresponsive negatively charged graft copolymer (Alg-g-PNIPAAm) with a brush-type structure, and an oppositely charged surfactant (DTAB), in bulk and at the air-solution interface. We performed experiments

Core-sheath nanofibers as drug delivery system for thermoresponsive controlled release [PDF]

open access: yes, 2017
In this work, a smart drug delivery system of core–sheath nanofiber is reported. The core-sheath nanofibers were prepared with thermoresponsive poly-(N-isopropylacrylamide) (PNIPAAm) (as core) and hydrophobic ethylcellulose (EC) (as sheath) by coaxial ...

Thermoresponsive low-power light upconverting polymer nanoparticles [PDF]

open access: yesMaterials Horizons, 2016
Low-power upconverting nanoparticles are presented that display highly efficient, temperature-dependent green to blue upconversion under aerated aqueous conditions. These features are useful for live cell and in vivo temperature sensing.

Effect of polymer chemistry on globular protein–polymer block copolymer self-assembly [PDF]

open access: yes, 2014
Bioconjugates of the model red fluorescent protein mCherry and synthetic polymer blocks with different hydrogen bonding functionalities show that the chemistry of the polymer block has a large effect on both ordering transitions and the type of ...
