▎ 摘  要

NOVELTY - Carbon nanomaterials - nanotubes or graphene, particles of which contain hydroxyl and/or carboxyl groups on the surface are modified by treating with a solution containing triethanolamine titanate and fatty acid derivatives - triethanolamine stearate or triethanolamine palmitate. The molar ratio of said fatty acid derivative to titanium ranges from 1:1 to 3:1, and the weight ratio of said fatty acid derivative and titanium compounds with respect to titanium dioxide to nanotubes or graphene ranges from 0.75:1 to 2:1. The obtained suspension is treated with carbon dioxide gas until coagulation of the system and the precipitate is then washed with water. USE - Chemistry. ADVANTAGE - Obtained modified carbon nanomaterial disperses well in nonpolar media without using ultrasound.2 cl, 1 tbl, 9 ex
