METHOD FOR THE PREPARATION OF AN ELECTRODE COMPRISING AN ALUMINIUM SUBSTRATE, ALIGNED CARBON NANOTUBES AND AN ELECTROCONDUCTIVE ORGANIC POLYMER, THE ELECTRODE AND USES THEREOF

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 DEG 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 preparedand a device for storing and returning electricity such as a supercapacitor comprising the electrode. 本发明涉及用于制备电极的方法，所述电极包括由铝基材料制成的基材、垂直取向的碳纳米管和导电聚合物基质，所述方法包括以下相继步骤：(a)在小于或等于650℃的温度，根据CVD(化学气相沉积)技术，在由铝基材料制成的基材上合成垂直取向的碳纳米管的毯绒
