Full description:
The aerosol-assisted CVD (Chemical Vapor Deposition) method leads to obtain dense arrays of aligned carbon nanotubes (CNTs), whose applications are promising, in particular in the field of supercapacitor electrodes for electrochemical storage of energy [1]. The growth of CNTs aligned on metallic substrates which act as current collectors in supercapacitor electrodes requires a lowering of the growth temperature of the aligned CNTs to a temperature below 650°C. The objective of the project is to control the synthesis of aligned CNT carpets on metal supports (Al sheets or alloys). The approach will be to adjust the synthesis parameters (temperature, gas, nature of the carbon precursors or the support ...) with the aim of controlling the characteristics of the CNTs (alignment, length ... ). On the other hand, we will try to understand the growth mechanisms by conducting ex-situ analyzes on samples obtained under particular conditions such as for example CNT/Al interface analyzes and in-situ analyzes directly during the synthesis of the nanotubes.
