DOI: 10.1039/C2JM34974D, PaperMarco Giardiello, Tom O. McDonald, Phillip Martin, Andrew Owen, Steve P. Rannard
A generic method for producing triple component hydrophobic inorganic-organic magnetic nanocomposite particles is presented, using emulsion-templated freeze-drying. This avoids typical oxidising conditions within in situ emulsion polymerisation, and results in conservation of superparamagnetism and Fe3O4 incorporation. The nanocomposite dispersions demonstrate responsive behaviour to imposed magnetic fields.
