Structural architecture and magnetism control of metal oxides using surface grafting techniques uri icon

abstract

  • Hydrophilic iron oxide Fe 3 O 4 nanoparticles (NPs) were prepared by a reverse micro-emulsion method. Functionalization of Fe 3 O 4 NPs was then carried out via surface graft polymerization to achieve outstanding magnetic property. Characterization results indicate that grafted core-shell Fe 3 O 4 displayed inverse spinel crystalline structure, while particle size and it's distribution were controlled accordingly. The ferromagnetic behavior (60 A m 2 kg -1 ) of grafted Fe 3 O 4 NPs was restored close to bulk value through enhancement of Fe-O ionic bond. 2013 Springer Science+Business Media Dordrecht.
