Investigation of Magnetic Electrodes in Conducting Polymeric Materials: Electrochemical Properties of a Fullerene[C 60 ]-Pd Polymer and Iron Oxide Magnetic Nanocomposite.

A composite of iron oxide magnetic nanoparticles and coordination fullerene polymer (C Pd ) was formed by chemical deposition of spherical polymer nanoparticles on iron oxide magnetic nanoparticles in benzene containing C and Pd(0) complexes. The composition of the composite can be controlled by the amount of magnetite and concentration of polymerization precursors as well as the time of polymerization. The magnetic composite material Fe O -γFe O /(C Pd ) was used as a model system to investigate its deposition on a magnetic electrode and its electrochemical properties. The iron oxide magnetic nanoparticles ensures both the magnetic activity of the composite and its nanostructured morphology. Both of these factors are responsible for the enhancement of the electrochemical activity of the polymer phase forming the composite in comparison to the pure polymer material deposited on the same magnetic electrode. In the magnetic field of the electrode, the composite undergoes permanent and strong bonding with the surface of the electrode. The nanostructured morphology of the Fe O -γFe O /(C Pd ) composite also provides very good capacitive properties. This article is protected by copyright. All rights reserved.
