A dispersible paste comprising single-walled carbon nanotubes (SWNT) in water or in an organic solvent is prepared. The method of preparing the dispersible paste generally includes the following steps: a) removal of the catalyst used during the synthesis of SWNT; b) the SWNT remains wet and the desired paste Adding an appropriate amount of solvent, preferably at a solvent / SWNT ratio that varies between 30: 1 and 100: 1, depending on the viscosity of the; and c) a high energy horn using a dismembrator probe Sonication process. The resulting paste is suitable for facilitating redispersion in a solvent and incorporation into various matrices such as polymers. |
