Jet stream: Multi-walled carbon nanotubes grown by catalytic chemical vapor deposition were carboxylated in a two-step oxidation process. An aqueous dispersion of the functionalized nanotubes was dispensed using an inkjet printer to obtain electrically conductive patterns on paper and plastic surfaces (see picture). Sheet resistivities for the deposited patterns of about 40 kΩ/□ could be achieved by multiple prints.
