Abstract	It is shown that multi-walled carbon nanotubes (MWNT) form stable suspensions in isopropanol solvent as a result of influence of ultra-sound in the weight range of concentrations from 0.0001% to 1% by weight. Nonionic surfactant Triton X-165 affects the microstructure of the MWNT aggregates in isopropanol, a small amount of surfac- tant increase the intervals between the aggregates and accelerate the sedimentation process. MWNT suspension in and toluene shows unstable behavior, their total precipi- tation time is less than 104 sec. Addition of 0.4% Triton X-165 to suspension of MWNT in p-xylene leads to its stabilization. Also, addition of 0.6% Triton X-165 leads to partial stabilization of suspensions of MWNT in toluene.
