Abstract: Herein, the synthesis of a novel nitroxide-mediated polymerization (NMP) initiator bearing a photolabile ortho-nitrobenzyl (oNB) group allowing surface-initiated NMP preparation of well-defined photoresponsive polystyrene grafted on silica nanoparticles is described. The photocleavable and photoresponsive properties… read more here.

Abstract: Polymer-tethered nanoparticles provide a strategy to improve particle dispersion in polymer nanocomposites and as materials themselves can exhibit self-healing behavior and enhanced mechanical properties. The few studies that previously characterized the glass transition temperature (Tg)… read more here.

Abstract: A magnetic mesoporous carbon material (Fe3O4@C) was fabricated by carbonizing polystyrene grafted polydopamine-coated magnetic nanoparticles. The chemical composition, morphology and magnetism of the mesoporous carbon materials were characterized. The as-prepared magnetic mesoporous carbon was employed… read more here.
