Abstract: A new composite consisting of nanosized powders of hexaferrites BaFe12O19 (BaM), multiferroics Co1.6Zn1.4W+CaTiO3 (30%), carbon nanostructures (powder mixture of carbon nanotubes, fullerenes, squamous structures and amorphous carbon) and silicone binder absorbs microwaves. Varying the concentration of each component in the composite materials changes the characteristics of a coating from reflective to absorbing electromagnetic radiation. Adding a layer with multiferroics to a composite material significantly improves the coatings as protective layer from microwaves.
