Resumo: 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).

A partir dos nanocompósitos obtidos, os parâmetros complexos de permissividade elétrica, permeabilidade magnética e refletividade foram estudados na faixa de frequência da banda X, 8,2 a 12,4 GHz. Os resultados de refletividade dos nanocompósitos obtidos com os NTC funcionalizados apresentaram uma atenuação de, -21 dB e -18 dB, na frequência de 10,4 GHz e 12,4 GHz, respectivamente, com aproximadamente 99% de atenuação, demostrando serem promissores para aplicação como material absorvedor de radiação eletromagnética (MARE).IBICT2022-04-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revista.univap.br/index.php/revistaunivap/article/view/258210.18066/revistaunivap.v28i57.2582Revista Univap; Vol. 28 No. 57 (2022): Revista Univap onlineRevista Univap; v. 28 n. 57 (2022): Revista Univap online2237-17531517-327510.18066/revistaunivap.v28i57reponame:Revista UniVap (online)instname:Universidade do Vale do Paraíba (Univap)instacron:UNIVAPenghttps://revista.univap.br/index.php/revistaunivap/article/view/2582/2166Copyright (c) 2021 Revista Univapinfo:eu-repo/semantics/openAccessda Silva, Valdirene AparecidaDonati, Bruno FerrazCorsato, Cecília MaiaFonseca, Nicholas ErasOliveira, Rademaks BentoPassos, Rafaela RealMalère, Caroline Paganucci dos Reis2022-11-03T17:55:21Zoai:ojs.biblioteca.univap.br:article/2582Revistahttps://revista.univap.br/index.php/revistaunivapPRIhttps://revista.univap.br/index.php/revistaunivap/oairevista@univap.br2237-17532237-1753opendoar:2022-11-03T17:55:21Revista UniVap (online) - Universidade do Vale do Paraíba (Univap)false
