Synthesis of Hybrid Materials Based on Multiwalled Carbon Nanotubes Decorated with WC1 –x Nanocoatings of Various Morphologies

New hybrid materials based on multiwalled carbon nanotubes (MWCNTs) with a nonstoichiometric tungsten carbide coating (WC 1 – x /MWCNTs) were synthesized by metalorganic chemical vapor deposition with tungsten hexacarbonyl used as a precursor. The mass ratio of precursors was varied to obtain nonsto...

Zusammenfassung:New hybrid materials based on multiwalled carbon nanotubes (MWCNTs) with a nonstoichiometric tungsten carbide coating (WC 1 – x /MWCNTs) were synthesized by metalorganic chemical vapor deposition with tungsten hexacarbonyl used as a precursor. The mass ratio of precursors was varied to obtain nonstoichiometric tungsten carbide coatings of different morphologies ranging from spatially separated nanoparticles to a uniform ~300-nm-thick coating with a granular structure.
