DISPERSION OF CARBON NANOTUBES Russian patent published in 2013 - IPC C01B31/02 B82B3/00 B82Y30/00 B82Y40/00

Abstract RU 2494961 C2

FIELD: chemistry.

SUBSTANCE: invention can be used in obtaining modifying additives for construction materials. Dispersion of carbon nanotubes contains, wt %: carbon nanotubes 1-20; surface-active substance - sodium salt of sulfonated naphthalene derivative 1-20; aerosil 5-15; water - the remaining part. Dispersion can additionally contain ethylene glycol as antifreeze.

EFFECT: dispersion is stable in storage, dissolves in water, ensures increase of strength of construction materials.
