NANOCOMPÓSITO POLÍMERICO DE POLIAMIDA 6 REFORÇADO COM ÓXIDO DE GRAFENO
PROCESSAMENTO VIA MISTURA EM SOLUÇÃO
Palavras-chave:
nanocompósito, reforço, grafeno, dispersão, náilon 6
Resumo
No presente estudo foram investigadas a síntese e caracterização de nanocompósitos de poliamida 6 reforçada com óxido de grafeno através da rota de mistura por solução. O óxido de grafeno foi sintetizado via método Hummers modificado, e o nanocompósito foi preparado em solução de ácido fórmico e posteriormente precipitado em água destilada. O material obtido foi então caracterizado para a avaliação da efetividade da metodologia empregada na dispersão do óxido de grafeno na matriz polimérica. As amostras foram caracterizadas através das técnicas de espectroscopia Raman, difração de raios X, termogravimetria e espectroscopias Raman e na região do infravermelho com transformada de Fourier. A rota de síntese do óxido de grafeno provou-se bastante eficiente, obtendo-se um material com alto grau de oxidação e esfoliação. Por meio dos resultados obtidos para o nanocompósito se pode comprovar a interação entre o reforço e a matriz polimérica, bem como as alterações estruturais de cristalinidade na poliamida 6 após a adição do óxido de grafeno. O nanocompósito produzido apresenta potencial aplicação como polímero de engenharia.
