Preparation of nearly monodispersed Fe3O4/SiO2 composite particles from aggregates of Fe3O4 nanoparticles

Author affiliations

Abstract

Nearly monodispersed sphere-like Fe3O4/SiO2 composite particles were prepared via a direct silica coating using Tween-80 of modified aggregates of Fe3O4 nanoparticles obtained by the emulsion droplet solvent evaporation method. The size and magnetite proportion of the composite particles were tunable by controlling the size of the aggregates and/or the thickness of the silica coating layer.
