Composite material based on iron-containing nanoparticles for applications in the problems of electromagnetic compatibility

The decomposition of iron formate is used to synthesize composite materials that represent ironcontaining nanoparticles localized in the high-pressure-polyethylene matrix with the concentration of the iron-containing component ranging from 10 to 40 wt %. The composition and structure of the materials are comprehensively analyzed using the transmission electron microscopy, X-ray phase analysis, Mössbauer spectroscopy, and electronic magnetic resonance. Electrophysical and magnetic properties of the synthesized materials and the coefficients of reflection and attenuation in the centimeter-wavelength range are studied. It is demonstrated that the composite materials can be used to provide electromagnetic compatibility, noise immunity, radio shielding, and protection of biological objects against electromagnetic radiation.
