Resumo

Neste trabalho o comportamento de cristalização e a condutividade elétrica de compósitos nanoestruturados de poli(sulfeto de fenileno) reforçado com nanotubos de carbono de paredes múltiplas obtidos através da técnica de mistura em fusão foram estudados. A incorporação do nanoreforço na matriz polimérica foi responsável por um aumento da cristalinidade devido ao fenômeno de nucleação heterogênea. A condutividade elétrica do PPS apresentou um aumento de 11 ordens de magnitude quando 2,0 m/m% de MWCNT foram adicionados a matriz polimérica. Além disso, o limite de percolação elétrica encontrado para este sistema foi de 1,4 m/m% de MWCNT, revelando a formação de uma rede condutiva tridimensional no interior da matriz polimérica.

Palavras-chave

PPS, MWCNT, cristalização, propriedades elétricas, limite de percolação elétrica.

Abstract

In this work, the crystallization behavior and electrical conductivity of multiwalled carbon nanotubes reinforced poly (phenylene sulfide) nanostructured composites obtained by melt mixing were investigated. The incorporation of nanofiller in polymeric matrix was responsible for an increase in crystallinity due heterogeneous nucleation phenomenon. The electrical conductivity of PPS showed an increase by 11 orders of magnitude when 2.0 wt% of MWCNT was considered. Moreover, the electrical percolation threshold found on this system was 1.4 wt%, suggesting the formation of three‑dimensional conductive network within the polymeric matrix.

Keywords

PPS, MWCNT, crystallization, electrical properties, electrical percolation threshold.
