METHOD OF OBTAINING DISPERSIONS OF CARBON NANOTUBES Russian patent published in 2014 - IPC C01B31/02 B82B3/00 B82Y40/00

Abstract RU 2531172 C2

FIELD: chemistry.

SUBSTANCE: invention can be used in manufacturing polymer-based composites. Carbon nanotubes are functionalised by carboxyl and/or hydroxyl groups and processed by ultrasound in an organic solvent in the presence of products of reaction of tetrabutyltitanate with stearic or oleic acid at a temperature from 40^oC to the temperature of the solvent boiling.

EFFECT: obtained dispersions of the carbon nanotubes are stable in non-polar organic solvents.
