Abstract

The invention relates to the growth of carbon nanotubes on a substrate, in particular a carbon or metal substrate on which the growth of such nanotubes is usually difficult. Accordingly, the invention includes a first phase that comprises depositing a ceramic sub-layer, followed by a second phase that comprises depositing carbon nanotubes on said sub-layer in a single step and in a single and same growth reactor. The growth can advantageously be carried out by chemical vapor deposition.
