42.3: Invited Paper: Silver nanowire for Next Generation Touch Solution

Abstract

We developed a continuous roll‐to‐roll process for the fabrication of electrodes of silver nanowire (AgNWs) networks. For high‐throughput flexible electronic devices to be ready for the market, their transparent conductive electrodes (TCEs) should show stable working performance during folding conditions and have a long operating life. In this study, TCEs were produced by AgNWs electrodes. The AgNWs electrodes showed an outstanding sheet resistance value of 50 ohm/sq, 92.3% transmittance, mechanical stability, and excellent long‐term stability. Flexible touch screen were produced using the AgNWs transparent electrodes on a flexible COP substrate. The touch screen performance is superior to that of a device based on the as‐coated AgNWs electrode. The roll‐to‐roll process provides a facile and reliable method for fabricating large‐area AgNWs transparent flexible electrodes for next‐generation flexible touch screen devices.
