Abstract:
A transparent conductive article includes a transparent substrate, a thin electrically conductive grid, and a carbon nanolayer. The grid is disposed on the substrate, and the carbon nanolayer is also disposed on the substrate and in contact with the grid. The conductive grid and the carbon nanolayer may have thicknesses of no more than 1 micron and 50 nanometers, respectively. The carbon nanolayer has a morphology that includes graphite platelets embedded in nano-crystalline carbon, and can be produced with a buffing procedure using dry carbon particles without substantially damaging the grid structure. The article may have a visible light transmission of at least 80%, and a sheet resistance less than 500 or 100 ohms/square. The transparent substrate may comprise a flexible polymer film. The disclosed articles may substantially maintain an initial sheet resistance value when subjected to flexing.
