Thermosensitive PNIPAAm cryogel with superfast and stable oscillatory properties

Chemical Communications, 2003
Through copolymerization/crosslinking in dimethyl sulfoxide (DMSO) at temperature below the melting point of DMSO, we demonstrated a novel poly(N-isopropylacrylamide) (PNIPAAm) hydrogel with regularly oriented micromatrix; the superfast/stable oscillatory hydration-dehydration character of this hydrogel would find wide applications in biomedical field.

Characterization and cell material interactions of PEGylated PNIPAAM nanoparticles

Colloids and Surfaces B: Biointerfaces, 2010
The aim of this study was to investigate the haemocompatibility of poly(N-isopropylacrylamide)-co-poly(ethylene glycol), PNIPAAM-PEG based nanoparticles and the influence of poly(ethylene glycol), PEG on the interactions of nanoparticles with cells.

Grafting PNIPAAm from β-barrel shaped transmembrane nanopores

Biomaterials, 2016
The research on protein-polymer conjugates by grafting from the surface of proteins has gained significant interest in the last decade. While there are many studies with globular proteins, membrane proteins have remained untouched to the best of our knowledge.

Selective adsorption of oppositely charged PNIPAAM on halloysite surfaces: a route to thermo-responsive nanocarriers

Nanotechnology, 2018
Halloysite nanotubes were functionalized with stimuli-responsive macromolecules to generate smart nanohybrids. Poly(N-isopropylacrylamide)-co-methacrylic acid (PNIPAAM-co-MA) was selectively adsorbed into halloysite lumen by exploiting electrostatic ...

Thermo‐Responsive PNIPAAm Copolymers with Hydrophobic Spacers

Macromolecular Symposia, 2007
AbstractWe have synthesised and characterised three sets of acryloyl(amino‐acid)/NIPAAm co‐polymers. Three different co‐monomers were synthesised and copolymerized with N‐isopropylacrylamide (NIPAAm) by free radical polymerization in different molar ratios (12:1, 9:1, and 6:1). All series contain aliphatic spacers and are carboxylic terminated.

Mechanical and rheological behavior of pNIPAAM crosslinked macrohydrogel

Reactive and Functional Polymers, 2013
In this study for the first time we investigate the most common reticulated N-isopropylacrylamide (pNIPAAM) macrohydrogel for both its mechanical response and shear rheological behavior in time and frequency domains. Hydrogels are characterized by water content volume and weight measurements, FT-IR spectroscopy, scanning electron microscopy and ...

Preparation of thermo-responsive PNIPAAm-MWCNT membranes and evaluation of its antifouling properties in dairy wastewater.

Materials Science and Engineering C: Materials for Biological Applications, 2019
A novel MWCNT-PNIPAAm nanocomposite membrane was developed with an excellent cleaning efficiency of thermo-responsive surface. The thermo-responsive N-isopropyle acryleamide (NIPAAm) monomer was polymerized on the surface of MWCNT via free radical ...

Protein Resistance of PNIPAAm Brushes: Application to Switchable Protein Adsorption

Langmuir, 2009
Protein adsorption, as the primary process occurring when a foreign surface comes into contact with a biosystem, was studied on thin polymer brush films consisting of poly(N-isopropylacrylamide) (PNIPAAm) and poly(2-vinylpyridine) (P2VP). These films were prepared by the "grafting to" method. The protein resistance of stimuli responsive PNIPAAm-brushes
