Propriétés physiques de nanocomposites NTC-polyepoxy: influence du traitement de surface des NTC
Abstract
Polymeric matrix nanocomposites provide great opportunities to overcome macroscopic properties of polymers. The shape factor of nanofillers is a key parameter, so carbon nanotubes (CNTs) have attracted much interest. To avoid aggregation, mechanical stirring has been used. In those conditions, the percolation threshold of conductivity is reached at 0.15 wt % for CNTs. To improve the shape factor, amphiphilic molecules have been successfully used: in this case, the percolation threshold is at 0.04 wt % for CNTs. After the percolation threshold, such nanocomposites allow the elimination of electric charges, while keeping the same mechanical properties than the polymeric matrix. RÉSUMÉ : Les nanocomposites à matrice polymère offrent de nouvelles opportunités pour améliorer les propriétés macroscopiques des polymères. Le facteur de forme des nanocharges est un paramètre clé, ce qui constitue le grand intérêt des nanotubes de carbone (NTC). Afin d’éviter les phénomènes d’agrégation un mélange mécanique a été utilisé. Dans ces conditions, le seuil de percolation électrique est de 0.15% en masse. Pour augmenter le facteur de forme, des molécules amphiphiles ont été utilisées : dans ce cas le seuil de percolation est de 0.04% en masse. Au dessus du seuil de percolation, ces nanocomposites permettent l’écoulement des charges électrostatiques tout en conservant les propriétés mécaniques de la matrice.
