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.
