Abstract

Silver metal patterns onto plastic substrates have been obtained by inkjet printing with commercial ink based on silver nanoscale particles. Morphological characterization by scanning electron microscopy of spin-coating processed films indicates that a sintering treatment at 250 degrees C for 30 min is enough to sinterize the silver metal nanoparticles. X-ray photoelectron spectroscopy characterization of sintered metal films shows that the sinterization is accompanied by a reduction of carbon surface concentration coming from carbon-containing chemical compounds present in the ink formulation. After sintering at 250 degrees C for 30 min, the material shows typical electrical resistivity of 4.6 x 10(-6) Omega cm (i.e. about three times the value of bulk silver).Printed test structures show typical resistivity after sintering at 250 degrees C for 30 min in the range of 5-7 x 10(-6) Omega cm.
