Abstract

To create materials that interact effectively with electromagnetic (EM) radiation, new nanosized substituted ferrites (NiZn)_1-xMn_xFe₂O₄ (x = 0, 0.5, and 1) anchored on the surface of multi-walled carbon nanotubes (CNTs) have been synthesized. The concentration of CNTs in the (NiZn)_1-xMn_xFe₂O₄/CNT system was from 0.05 to 0.07 vol. fractions. The dielectric and magnetic characteristics of both pristine (NiZn)_1-xMn_xFe₂O₄ ferrites and (NiZn)_1-xMn_xFe₂O₄/CNT composite systems were studied. The introduction of (NiZn)_1-xMn_xFe₂O₄/CNT composites into the amorphous epoxy matrix allows to tailor absorbing properties at the high-frequency by effectively shifting the maximum peak values of the absorption and reflection coefficient to a region of lower frequencies (20-30 GHz). The microwave adsorption properties of (NiZn)_1-xMnxFe₂O₄/0.07CNT-ER (x = 0.5) systems showed that the maximum absorption bandwidth with reflection loss below -10 dB is about 11 GHz.

Keywords: absorption coefficient; carbon nanotubes; nanosized spinel ferrites; polymer matrix systems; reflection loss.
