1. A method for providing a substrate made of a porous carbonaceous material with vertically aligned carbon nanotubes on a surface and in a body thereof,
said method having a first step of depositing a ceramic sublayer on said substrate followed by a second synthesis step, by catalytic chemical vapour deposition, of said vertically aligned carbon nanotubes on the substrate obtained following the first step, to obtain a substrate having vertically aligned carbon nanotubes on the surface and in the body thereof, and wherein the vertically aligned carbon nanotubes on the surface and in the body of the substrate are vertically aligned relative to the plane of the substrate; and
wherein a carbon source required for the synthesis during the second step is injected in a substantially perpendicular direction to the plane of the substrate and at a pressure between 3×104 Pa and 6×104 Pa.
