Abstract
(EN)
The present invention relates to a method for the preparation of an electrode comprising a substratemade 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 mat of vertically aligned carbon nanotubes according to the technique of chemical vapour deposition (CVD) at a temperature less than or equal to 650°C; (b) electrochemically depositing the polymer matrix on said carbon nanotubes from an electrolyte solution comprising at least one precursor monomer of the matrix, at least one ionic liquid and at least one protic or aprotic solvent. The present invention also relates to the electrode thus prepared and a device for storing and returning electricity such as a supercapacitor comprising the electrode.
