processo para obtenção de filamentos para impressoras 3d contendo nanocompósitos de polímeros e nanomateriais de carbono, produto e uso. a presente tecnologia refere-se a um processo de incorporação de nanomateriais de carbono, especialmente nanotubos de carbono e óxido de grafeno, em matrizes poliméricas termoplásticas, adequadas à impressão 3d do tipo fdm (fused deposition modeling). o processo permite a obtenção de compósitos com propriedades mecânicas, térmicas e elétricas superiores aos polímeros puros.
