We have developed the silver nanoparticle ink and printed invisible fine silver grid lines with 5 μm width on a film substrate by a gravure offset method. Then the grid lines are laminated with a conductive polymer. In optimizing the electrodes of the silver grid lines laminated with the conductive polymer, the transmittance is up to 96% in the visible light region and the sheet resistance is down to 4 Ω/sq. The sheet resistance and transmittance are possible to be tailored by adjusting filling fraction of the electrodes. The transparent electrodes of the silver grid lines laminated with the conductive polymer would have potential applications as a flexible and transparent conductive film in optoelectronic devices.
