Electrophysical Properties of Polymeric Nanocomposites Based on Barium Ferrites Modified by Copper Iodide

Barium ferrites modified with copper iodide were synthesized by the sol– gel-autocombustion method. The sizes of barium-ferrite crystallites for all samples were of 20–50 nm. The magnetic and electrophysical properties of CuI/ferrite-filled polychlorotrifluoroethylene (PCTFE) composites are investigated in the microwave range at ambient temperature. As shown, the introduction of CuI/ferrite composites into PCTFE leads to an increase of the values of the complex dielectric permittivity magnitude by 2–5 times in comparison with the system containing the unmodified component.
