Caracterização eletromagnética do compósito de carbeto de silício e negro de fumo em matriz polimérica

Abstract: RESUMO Este trabalho apresenta as propriedades eletromagnéticas de um Material Absorvedor de Radiação Eletromagnética (MARE) feito a partir de Carbeto de Silício (SiC) e Negro de Fumo (NF) como aditivos. O compósito SiC/NF foi produzido utilizando 70 %(m/m) de matriz de silicone, e variando as concentrações do aditivo em 3 %(m/m), 2 %(m/m) e 1 %(m/m) de NF com 27 %(m/m), 28 %(m/m) e 29 %(m/m) de SiC, respectivamente. A estrutura química e a morfologia das partículas de SiC e NF foram analisadas através de espe… Show more

“…The ink presented an intermediate ratio of the precursor materials (GR and CB), which can be justified by the presence of CB, altering the graphitic structure, and presenting a higher degree of defect when compared to the value of the ratio for the graphite sample. Therefore, the results indicated that the final composition of the ink has the presence of precursor materials used in the synthesis [33,34].…”
