FIELD: metallurgy.
SUBSTANCE: multiwall carbon nanotubes (MWCN) in powder form 14 are placed in reactor 12, pre-vacuum is created in its volume and the nanotubes are mixed by reverse rotation within 270°. Then, the nanotubes are heated by pyrolysis furnace 15 and vapours of aluminium organometallic compound are supplied-tri-isobutyl aluminium from ampoule 3, heated in evaporator furnace 2 to 50-70°C. As a result of pyrolysis, at temperature 250-300°C, tri-isobutylaluminium decomposes and hybrid material is formed on the basis of MWCN, the surface of which is decorated by remotely separated crystalline alumina nanoparticles. Volatile pyrolysis products are removed from reactor 12 through tube 18 and collected in the trap. Simplified technology for obtaining a hybrid material based on MWCN decorated by remotely separated crystalline aluminium nanoparticles.
EFFECT: resulting commercial product requires no additional flushing by solvents and drying.
