Abstract
A uniform distribution of carbone nanotubes in a polymer matrix is required for the fabrication of composite materials. Since carbon nanotubes for introduction into polymers are preliminarily dissolved in water or organic solvents, it is necessary to create a uniform stable dispersion of carbon nanotubes in solvents. It is shown in this work that the concentration of nanotubes is a critical parameter determining the stability and composition of a solution. The kinetics of agglomeration of multiwalled carbon nanotubes dispersed in chloroform by sonication has been studied using optical spectroscopy and dynamic light scattering. It has been shown that such solutions can be stable for a long time at nanotube concentrations below 0.01 wt %. The intense agglomeration and sedimentation of nanotubes have been observed in a solution with a higher concentration.
