Abstract
A method for providing a substrate made of a porous carbonaceous material with vertically aligned carbon nanotubes, the method having a first step of depositing a ceramic underlayer on the substrate followed by a second step of synthesizing, by catalytic chemical vapour deposition, the vertically aligned carbon nanotubes on the substrate obtained after the first step, the carbon source necessary for the synthesis during this second step being injected in a direction substantially perpendicular to the plane of the substrate and at a pressure less than 8104 Pa (800 mbar). The use of the substrate for preparing an electrode such as a supercapacitor electrode.
