Facile approach for superparamagnetic CNT - Fe3O4 / polystyrene tricomponent nanocomposite via synergetic dispersion / Wu Zhong in Industrial & engineering chemistry research, Vol. 51 N° 37 (Septembre 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 37 (Septembre 2012) . - pp. 12017–12024 Titre : Facile approach for superparamagnetic CNT - Fe3O4 / polystyrene tricomponent nanocomposite via synergetic dispersion Type de document : texte imprimé Auteurs : Wu Zhong, Auteur ; Peng Liu, Auteur ; Zhaobin Tang, Auteur Année de publication : 2012 Article en page(s) : pp. 12017–12024 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Nanocomposite  Synergetic  dispersion Résumé : A facile one-pot in-situ radical bulk polymerization strategy was developed for preparation of the superparamagnetic multiwalled carbon nanotubes-Fe3O4/polystyrene (CNT-Fe3O4/PS) tricomponent nanocomposite by the synergetic dispersion strategy via the multiwalled carbon nanotubes (CNT) immobilized Fe3O4 nanoparticles (CNT-Fe3O4) with oleic acid (OA) as surface modifier. Compared with the tricomponent nanocomposite prepared with the multiwalled carbon nanotubes and Fe3O4 nanoparticles added separately, immobilization of Fe3O4 nanoparticles on multiwalled carbon nanotubes could avoid efficiently aggregation of the Fe3O4 nanoparticles in polymer matrices. OA molecules adsorb onto the surfaces of the Fe3O4 nanoparticles immobilized on the multiwalled carbon nanotubes, improving efficiently the dispersibility of the multiwalled carbon nanotubes in styrene, which resulted in the well-dispersed CNT-Fe3O4/PS tricomponent nanocomposite.
