Popis: Carbon nanotubes (CNT) were functionalized with ethanol, nitric and sulfuric acid. From the obtained nanocomposites, electrical permittivity, magnetic permeability and reflectivity complex parameters were studied in the frequency range of 8.2 to 12.4 GHz (X-band). The results of reflectivity for nanocomposites, functionalized with CNT, showed an attenuation of - 21 dB and -18 dB, at the frequency of 10.4 GHz and 12.4 GHz, respectively, with approximately 99% of attenuation, demonstrating, then, that they are promising for application as Radar Absorbing Materials (RAM).
