Flexible production technologies and equipment based on atmospheric pressure plasma processing for 3D nanostructured surfaces
Duration: June 2009 - May 2013
In this project, fast and scalable deposition processes for catalytic thin films and for the growth of carbon nanotube (CNT) films on flexible conductive substrates were established based on wet-chemical dip-coating and chemical vapour deposition at atmospheric pressure allowing the control of CNT diameter and film morphology. For the electrochemical characterisation as supercap electrode, a cell configuration was designed and indeed the unique electronic structure of vertical-oriented CNT films was confirmed to be advantageous in electrochemical energy storage applications. Low series resistance was observed for all CNT electrodes in the electrochemical test cell indicating fast ion-transport in the inter-tube channels and high intrinsic electronic conductivity of the CNT.
