Atom transfer radical polymer-modified paper for improvement in protein fixation in paper-based ELISA

BMC Chemistry, 2019
A newly modified paper-based enzyme-linked immunosorbent assay (P-ELISA) was established by immobilizing more proteins on the paper surface through an atom transfer radical polymerization (ATRP) reaction.

Functional supramolecular tetrathiafulvalene-based films with mixed valences states [PDF]

, 2016
Tetrathiafulvalene molecules substituted with a carboxylic acid group (TTFCOOH) were bound as redox-active moieties into a poly(4-vinyl pyridine) (P4VP) skeleton through non-covalent interactions (hydrogen bonds). The aspect of the resulting P4VP-TTFCOOH

Adjustment of Coatings Morphology and Particle Distribution of Layered Silicates by Freeze‐Drying for Improved Gas Barriers

Advanced Engineering Materials, EarlyView.
Freeze‐drying of layered silicate is the key to get coatings with superior gas barrier. Freeze‐drying of layered silicates modified with dodecylamine (DDA) is a highly effective technique for the preparation of barrier pigments that significantly mitigate the permeation of oxygen, water vapor, and hydrogen through polymer films containing these ...

“One-pot” dispersion ATRP and alkyne-azide Huisgen’s 1,3-dipolar cycloaddition in supercritical carbon dioxide: towards the formation of functional microspheres [PDF]

, 2010
Functional polymers were successfully prepared in scCO2 by combining alkyne-azide 1,3-dipolar Huisgen’s cycloaddition and dispersion ATRP in a “one pot” process using new perfluorinated polymeric amino-based ligands that had a dual role, i.e.

X‐Ray Tomography Analysis of Damage Mechanisms in Metal Matrix Syntactic Foams During Compression

Advanced Engineering Materials, EarlyView.
In situ synchrotron X‐ray tomography is used to investigate the internal damage mechanisms of AlSi12 metal matrix syntactic foam with ceramic hollow spheres during compressive loading. It is concluded that a homogeneous distribution of the second‐phase filler material results in a sequential collapse in a localized region; this leads to controlled and ...

Synthesis and reactivity of self-immolative pDTT-g-pGMA bottlebrush polymer

eXPRESS Polymer Letters
Post-polymerization modification of self-immolative polymers expands the application spectrum of such macromolecular materials. This work demonstrates grafting of poly(glycidyl methacrylate) brushes from a self-immolative poly(DL-dithiothreitol) backbone

Preparation and Characterization of Hyperbranched Polystyrene Nanocomposite Synthesized by Living Radical Polymerization and Solution Intercalation Method [PDF]

علوم و تکنولوژی پلیمر, 2013
A copolymer of styrene and methyl styrene was synthesized by nitroxide - mediated “living” free radical polymerization )NMP). N-Bromosuccinimide was used as a brominating agent to obtain a copolymer with bromine as its end group.

Micropleated Nanofibrous Filters for High‐Efficiency Submicron Aerosol Filtration: A Comparative Study with Chemical, Biological, Radiological, and Nuclear Gas Mask Filters

Advanced Engineering Materials, EarlyView.
This study presents micropleated filters manufactured by needleless electrospinning. Nanofibers are deposited onto uniaxially pre‐stretched substrates that contract upon release, forming densely packed micropleats. This architecture increases effective surface area without enlarging the filter size, achieving quality factors comparable to those of ...

Origins and Development of Initiation of Free Radical Polymerization Processes

International Journal of Polymer Science, 2009
At present worldwide about 45% of the manufactured plastic materials and 40% of synthetic rubber are obtained by free radical polymerization processes. The first free radically synthesized polymers were produced between 1910 and 1930 by initiation with ...

In-situ syntheses of graft copolymers by metal-free strategies: combination of photoATRP and ROP

Designed Monomers and Polymers, 2020
A completely metal-free and environmentally friendly strategy is demonstrated for the preparation of graft copolymers by combining photoinduced Atom Transfer Radical Polymerization (ATRP) and Ring Opening Polymerization (ROP).
