Synthesis of Polystyrene/MCM–41 Nanocomposites through AGET ATRP and ARGET ATRP [PDF]

علوم و تکنولوژی پلیمر, 2015
Polystyrene/MCM–41 nanocomposites were synthesized by atom transfer radical polymerization (ATRP) at 110°C. Activators generated by electron transfer (AGET) and activators regenerated by electron transfer (ARGET), as two novel initiation techniques, for ...

Surface-Induced ARGET ATRP for Silicon Nanoparticles with Fluorescent Polymer Brushes. [PDF]

Polymers (Basel), 2019
Well-defined polymer brushes attached to nanoparticles offer an elegant opportunity for surface modification because of their excellent mechanical stability, functional versatility, high graft density as well as controllability of surface properties. This study aimed to prepare hybrid materials with good dispersion in different solvents, and to endow ...

ARGET-ATRP synthesis and characterization of PNIPAAm brushes for quantitative cell detachment studies. [PDF]

Biointerphases, 2012
Stimuli responsive (or “smart”) polymer brushes represent a non-toxic approach for achieving release of biofouling layers. Thermo-responsive poly(N-isopropylacrylamide) (PNIPAAm) polymer brushes have been shown to modulate bacterial adhesion and release through transition between temperatures above and below the lower critical solution temperature ...

Automated ARGET ATRP Accelerates Catalyst Optimization for the Synthesis of Thiol-Functionalized Polymers. [PDF]

Macromolecules, 2012
Conventional synthesis of polymers by ATRP is relatively low throughput, involving iterative optimization of conditions in an inert atmosphere. Automated, high-throughput controlled radical polymerization was developed to accelerate catalyst optimization and production of disulfide-functionalized polymers without the need of an inert gas.
