Mimicking Natural Surface Wettability with 3D Carbon Nanoarchitectures

Published on March 24, 2014

Synthesis and alignment of three dimensional architectures of carbon nanotubes (CNTs) is demonstrated.

Their formation starts from nanoscaled catalysts and interaction with reactive carbon species generated from a hydrocarbon source. The process leads to large spatially oriented CNTs with a high aspect ratio and offers the possibility to transfer these structures to variable substrates. Such CNT nanostructures represent hierarchical materials which allow to bridge the gap from nano to micro to macro dimensions. Engineering the surface of these 3D aligned CNT structures allows tailoring their surface wetting behavior from superhydrophilic to superhydrophobic.

Jörg J. Schneider is professor for Inorganic Chemistry at the Department of Chemistry at Technische Universität Darmstadt since 2003. Before he has held positions at the MPI für Kohlenforschung in Mülheim a.d. Ruhr, at the University of Essen and at the University of Graz, Austria. His main research is in materials chemistry and organometallic chemistry. Current research interests are focused towards synthesis and functional properties of carbon materials (CNTs and graphene), metal oxides (e g. TCOs for printed electronics) and their hybrids as well as multinuclear metal complexes of polycondensed aromatics.

Deepu J. Babu graduated with a MS from IIT Madras, India, and is currently pursuing research work towards his Dr. rer nat. in the group of Prof. Schneider. His research is centered on the synthesis and functional properties of vertically aligned carbon nanotube architectures.
