Inkjet printed, conductive, 25 μm wide silver tracks on unstructured polyimide

25 mu m wide, conductive silver tracks on untreated and unstructured polyimide have been produced by inkjet printing using standard 10 pL printheads. This was achieved by reducing the droplet size to similar to 2 pL by tailoring the waveform and by heating the print cartridge and the substrate to 55 degrees C. A simple formula was used to predict the track width. (C) 2009 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
