Electrodeposition of hybrid organic–inorganic films containing iron oxide

A novel method has been developed for the preparation of hybrid organic–inorganic films containing iron oxide. The method is based on cathodic electrodeposition of iron oxide nanoparticles in situ in a polyelectrolyte matrix. Prepared films were studied using thermogravimetric analysis and magnetic measurements. By manipulation of deposition conditions, the amount of the deposited material, deposit composition and magnetic properties could be varied. Magnetic measurements revealed that the nanocomposite films are superparamagnetic.
