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.

Method for preparing a porous carbonaceous substrate having carbon nanotubes on its surface and its body

A method for the preparation of an electrode comprising a substrate made of an aluminium based material, vertically aligned carbon nanotubes and an electrically conductive polymer matrix, the method comprising the following successive steps: (a) synthesising, on a substrate made of an aluminium based material, a carpet of vertically aligned carbon nanotubes according to the technique of CVD (Chemical Vapour Deposition) at a temperature less than or equal to 650&#xb0; C.; (b) electrochemically depositing the polymer matrix on the carbon nanotubes from an electrolyte solution including at least one precursor monomer of the matrix, at least one ionic liquid and at least one protic or aprotic solvent. Further disclosed is the prepared electrode and a device for storing and returning electricity such as a supercapacitor comprising the electrode.
