METHOD OF OBTAINING CARBON NANOMATERIAL WITH APPLIED SILICON DIOXIDE Russian patent published in 2014 - IPC C01B31/02 C01B33/12 C04B35/528 B82B3/00 B82Y30/00 

FIELD: chemistry.

SUBSTANCE: invention can be used in obtaining composite materials. Initial carbon nanomaterials, for instance, nanotubes, nanothread or nanofibres, are processed in mixture of nitric and hydrochloric acid at temperature 50-100°C for not less 20 min, washed with water and dried. After that, it is empregnated with alcohol solution of oligoorganohydride siloxane, for instance, oligoethylhydride siloxane or oligomethylhydride siloxane, evaporated, air-dried at temperature not higher than 200°C for not less than 20 min, then tempered in inert medium at temperature 600-800°C for not less than 20 min.

EFFECT: obtained carbon nanomaterials with applied silicon dioxide have high resistance to oxidation.
