In this paper, a high Molecular weight organic compound, poly(N-vinyl-2-pyrrolidone) (PVP), was added to silver nitrate to fabricate silver conductive lines and arrays by inkjet printing oil flexible Kapton Substrates. With the assistance of PVP, the dimension of conductive lines can be controlled more accurately. In addition, the morphological control and resolution of arrays and lines were further improved by using UV/O(3) treatment of substrates and changing the Substrate temperature. The silver nitrate/PVP inks call be reduced in ethylene glycol vapor to form silver conductive lines at low temperatures. By using a high concentration of silver nitrate/PVP ink, continuous and smooth silver conductive lines with a resistivity of 2.7 1 x 10(-5) Q cm have been produced. Their resistivity is close to (lie resistivity of bulk silver.
