Preparation and Characterization of Silane Modified Fe3O4 Nanoparticles by Reverse Micro-Emulsion

Article Preview

Abstract:

Hydrophilic Fe3O4 nanoparticles (NPs) were prepared by reverse micro-emulsion, in which OP-10 as surfactant, n-butanol as co-surfactant, cyclohexane as oil phase, FeSO4·7H2O and FeCl3·6H2O aqueous solution as water phase. The as-prepared Fe3O4 NPs were functionalized by using of silane coupling agent 3-glycidoxypropyltrimethoxysilane (KH-570) to promote adhesion at the inorganic and organic interface (s). From the experimental results, it was found that the modified Fe3O4 NPs were of inverse spinel crystalline structure, and both Fe3O4 and modified Fe3O4 NPs exhibited super-paramagnetic behavior due to it near zero coercivity value.
