Core-shell Magnetic Particles with Controlled Electromagnetic Properties in Radiofrequency Band
Original language description
The present work is devoted to the development of magnetic materials with controlled electromagnetic properties (complex permittivity and permeability) in the radiofrequency band with a view to design radio absorbing materials. The objects of investigation are hybrid composites based on magnetic particles with core-shell structure. These materials are synthesized by oxidative polymerization of aniline and pyrrole in the presence of multi-domain MnZn ferrite particles using strong and weak oxidants. In this case, polyaniline and polypyrrole films grow on the surface of ferrite during the synthesis and their structure are formed under the influence of interactions between conducting polymer and ferrite. It is shown that the electromagnetic properties ofMnZn ferrite conducting polymer composites can be controlled by changing the properties of polymer coating (thickness, density, and conductivity) through the choice of the reaction conditions and the post-polymerization treatment of polym
