  • CORONA PATTERNING OF OVERCOATED NANOWIRE TRANSPARENT CONDUCTING COATINGS
    Publication number: 20150076106
    Abstract: A method comprising: providing a transparent electrically conductive film comprising: a transparent substrate (14); a composite layer (18) comprising: an electrically conductive layer disposed on at least a portion of a major surface of the transparent substrate (14) and comprising a plurality of interconnecting metallic nanowires (12); and a polymeric overcoat layer disposed on a portion of the electrically conductive layer, to provide a coated area of the electrically conductive layer; and patternwise exposing the coated area of the electrically conductive layer to a corona discharge to provide a patternwise exposed electrically conductive film comprising (1) an un exposed region (122) of the coated region having a first electrical resistivity, and (2) an exposed region (121) having a second electrical resistivity; wherein the exposed region is less electrically conductive than the unexposed region, and wherein there is a ratio of the second electrical resistivity over the first electrical resistivity of at

  • LASER PATTERNING OF SILVER NANOWIRE - BASED TRANSPARENT ELECTRICALLY CONDUCTING COATINGS
    Publication number: 20140332254
    Abstract: A transparent electrical conductor (10; 20), comprising a transparent substrate (14; 201); a composite layer (18; 28) comprising an electrically conductive layer (12) disposed on at least a portion of a major surface of the transparent substrate (14; 201) and comprising a plurality of interconnecting metallic nanowires, and a polymeric overcoat layer (16) disposed on at least a portion of the electrically conductive layer (12); wherein a pattern in the composite layer includes an x-axis and a y-axis of an x-y plane of the composite layer and a z-axis into the x-y plane of the composite layer, and the pattern defines a plurality of electrically conductive regions (24, 24?) in the x-y plane of the composite layer (18; 28), wherein the electrically conductive regions (24, 24?) are separated from each other by electrically insulative traces (21), each of which defines a valley into the z-axis of the x-y plane of the composite layer (18; 28), the valley having a maximum depth (27) in a range from 50 nanometers to
