Influence of Structural Features and Physico-chemical Properties of Metal-carbon Nanocomposites with Ferromagnetic Metal Inclusions on Microwave Radiation
Metal-carbon nanocomposites on the basis of polyacrylonitrile and compounds of metals (Fe, Ni, Co) synthesized at IR-heating and studied by SEM, X-ray phase analysis, Raman scattering, IR Fourier spectroscopy are characterized by the carbon nanostructured amorphous graphite matrix with uniformly dis...

| description | Metal-carbon nanocomposites on the basis of polyacrylonitrile and compounds of metals (Fe, Ni, Co) synthesized at IR-heating and studied by SEM, X-ray phase analysis, Raman scattering, IR Fourier spectroscopy are characterized by the carbon nanostructured amorphous graphite matrix with uniformly distributed nanoparticles of metals (10-30 nm), their oxides and compounds – FeNi3 and FeCo, multilayered carbon nanotubes (~ 7-22 nm), and in the composition of Fe-Co / C fullerene-like formations – C60. All nanocomposites feature high absorption of electromagnetic waves in the frequency range 20-40 GHz. Two absorption mechanisms are proposed: dielectric loss in the amorphous carbon matrix and scattering of electric and magnetic components by ferromagnetic inclusions. Absorption was – 8.68 dB for Fe-Ni / C, – 12.93 dB for Fe / C, and – 7.07 dB for Ni / C and for Fe-Co / C was found to be maximum in the whole range studied (more than – 40 dB) with a peak of – 52.83 dB at 24.27 GHz, which is explained probably by both high nanocomposite electric conductivity 2 S / m and high specific magnetization of phase FeCo. |
