Abstract

In this paper, we report the synthesis and characterization of the PMMA-coated magnetite nanocomposite obtained from the emulsion polymerization method. In this approach, the magnetite particles were prepared separately with oleic acid as the capping ligands in nonaqueous solution and disperse in non-polar solvent. The micells structure consisting water, oil phase and surfactant will contain the oleic acid stabilized magnetite particles inside and the polymerization process will only occur on the surface of the emulsion system. This method allows the individual magnetic particles encapsulated in the polymer matrix. The resulting nanocomposites were characterized by TGA, XRD and SQUID
