Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 47 N°17 (Septembre 2008) . - p. 6358–6361 Titre : Preparation of functional nanoparticles by assembling block copolymers formed by living radical polymerization Type de document : texte imprimé Auteurs : Tomomi Sato, Auteur ; Sakiko Tsuji, Auteur ; Haruma Kawagauchi, Auteur Année de publication : 2008 Article en page(s) : p. 6358–6361 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : PGLM core/PNIPAM Block copolymers Magnetite nanoparticles Résumé : A series of poly(glycerol methacrylate) (PGLM)-block-poly(N-isopropylacrylamide) (PNIPAM)s were prepared by quasi-living radical polymerization using a photosensitive iniferter. PGLM core/PNIPAM shell particles were prepared by self-assembling of the block copolymers in a methanol−tetrahydrofuran solution followed by cross-linking of the core. Magnetite nanoparticles were prepared in situ using penetrated ferric and ferrous ions in the core. The composite particles were stably dispersed in water at room temperature but easily collected by a magnet at the temperature above the lower critical solution temperature of PNIPAM.
