Preparation of Polystyrene / Fe₃O₄ Magnetic Composite Microspheres

Abstract:

Polystyrene/Fe₃O₄ composite microspheres were prepared by miniemulsion polymerization. The composite microspheres comprised of polystyrene core and magnetite nanoparticles as shell. Magnetite is modified with silane coupling to modify strong hydrophilic property, for a function of co-stabilizer. Acrylic acid as a co-monomer was employed to link polymer with magnetite nanoparticles. The microspheres were homogeneous distribution, The thickness of the shell was from10nm to 25nm. The morphology and structure of the composite microspheres were characterized by FT-IR, TEM, XRD, TG and XPS et al. The Effects of co-monomer, auxiliary emulsifier, emulsifier on the composite microspheres have been discussed.
