CA 2668489

The invention relates to a method for dispersing carbon nanotubes (CNTs) in a continuous phase, especially in at least one dispersing agent. In said method, the carbon nanotubes, which are especially not subjected to a preliminary treatment, are dispersed in a continuous phase, particularly in at least one dispersing agent, in the presence of at least one dispersing agent while supplying enough power for the dispersion. The invention further relates to the dispersions obtained in said manner and the use thereof. The inventive method allows the carbon nanotubes (CNTs) to be dispersed at high concentrations and with a long shelf life.

L'invention concerne un procédé de dispersion de nanotubes de carbone (CNT) dans une phase continue, en particulier dans au moins un agent dispersant, procédé caractérisé en ce que les nanotubes de carbone, lesquels sont, notamment, non soumis à un prétraitement, sont dispersés dans une phase continue, en particulier dans au moins un agent dispersant, en présence d'au moins un agent dispersant, tout en fournissant un apport d'énergie suffisant pour la dispersion. L'invention concerne en outre les dispersions ainsi obtenues et leur utilisation. Grâce au procédé selon l'invention, les nanotubes de carbone (CNT) peuvent être dispersées à des concentrations élevées et avec une grande stabilité au stockage.
