Abstract
Parallel, separate, narrow tracks of nanoscaled cupric oxide, CuO, displaying a width of 100–150 μm were fabricated by inkjet printing using a molecular copper–keto-acidoximato complex as the precursor for ink formulation. Printed patterns were obtained on various inorganic substrates, such as silicon, silicon dioxide, or alumina. Annealing temperatures of 180–200 °C were employed for the decomposition of the printed precursor into the pure nanoscaled CuO phase. The inkjet-printed samples were cured at 450 °C to ensure their stability during gas-sensor tests at elevated temperatures. The printed material showed considerable promise for miniaturized gas-sensor cells and for the detection of low concentrations of carbon monoxide and hydrogen.
