Abstract
Deagglomeration of the carbon nanotube bundles were performed in an aqueous solutions of different chemical composition using ultrasound, cavitation, and rotating homogenizing treatment. Found that the degree of dispersion on the cavitation principle strongly depends on the concentration of CNTs in the water. Using organic compounds (C6H12O6) increases the efficiency of the dispersion. Ultrasound effect is manifested in the destruction of agglomerates CNTs and size. Processing in a universal homogenizer of water-soluble polymer and ionic surfactant system/CNTs had allowed obtaining highly stable solution with a particle size from 150 to 400 nm. The particle size depends on the concentration of components in the system. Utilizing the CNT/water-soluble polymer/ionic surfactant mixture coupled with homogenizer machine shows the best results in terms of the solution stability, particles size, and their distribution.
