METHOD OF PRODUCING HYBRID MATERIAL BASED ON MULTI-WALLED CARBON NANOTUBES WITH TITANIUM CARBIDE COATING Russian patent published in 2017 - IPC C23C16/32 B82Y30/00 

FIELD: nanotechnology.

SUBSTANCE: hybrid nanocomposite materials are composed of multi-walled carbon nanotubes and are sedimented on them using the method of chemical vapour deposition of an organometallic compound of titanium coatings of titanium carbide, and can be used in the electron emitters of flat-panel displays and in other automotive vacuum emission devices. A process of getting a nanocomposite hybrid material based on multi-walled carbon nanotubes with a titanium carbide coating, comprises placing a multi-walled carbon nanotubes in the reactor, creating a pre-vacuum reactor, heating multi-wall carbon nanotubes to a predetermined temperature, the supply of the organometallic titanium compound to the surface of the multiwalled carbon nanotubes, the pyrolysis of the organometallic titanium compound on the surface of multi-walled carbon nanotubes with titanium carbide coating deposition and removal of volatile organometallic compounds of titanium products of pyrolysis. As a starting compound, an organometallic titanium bis (cyclopentadienyl) titanium dichloride is used, and its pyrolysis is carried on the surface of multi-walled carbon nanotubes at a temperature below 850°C and not higher than 900°C.

EFFECT: technology simplification of titanium carbide coatings on the surface of multi-walled carbon nanotubes by using a titanium-containing organometallic precursor.
