Abstract
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° 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.
