Abstract

Selon l'invention, l'introduction de nanotubes dans un liquide permet de modifier les propriétés physiques et/ou chimiques de ce liquide. En effet, la dispersion de nanotubes dans des liquides permet de réaliser des améliorations en termes de transfert de chaleur, de propriétés électriques, de viscosité et de pouvoir lubrifiant. Toutefois, les nanotubes réagissent comme des particules hydrophobes et tendent à s'agglomérer dans les liquides. L'invention concerne des procédés destinés à préparer des dispersions stables de nanotubes et consistant à identifier des tensioactifs/dispersants pouvant disperser les nanotubes de carbone dans un milieu liquide aqueux ou à base de pétrole. Un dispersant approprié est choisi pour le nanotube de carbone et le milieu à base d'eau ou d'huile, ce dispersant étant dissous dans le milieu liquide, d'où la formation d'une solution. On ajoute alors le nanotube de carbone au dispersant contenant la solution par agitation, ultrasonication et/ou des combinaisons correspondantes.
