Abstract:
The present invention concerns a method for preparing a suspension of carbon nanotubes in an aqueous solution comprising the following successive steps consisting of subjecting an aqueous solution containing carbon nanotubes and a surfactant to at least one cycle of freezing in liquid nitrogen and thawing; and subjecting said thawed solution to an ultrasound treatment. The present invention also concerns a suspension of carbon nanotubes, and in particular a suspension of long carbon nanotubes, that can be prepared by such a method.
