最近出现的银纳米线网络作为一个显着的替代铟锡氧化物（ITO）透明电极。在这里，我们表明，这种银纳米线的替代品可以成功地使用相同的激光烧蚀技术通常用于制造ITO器件。作为概念验证，我们已经制造了一个完全运行的五英寸多点触摸高像素传感器，通常用于智能手机技术，并发现它可以基于ITO执行二进制转换。我们观察到，激光加工银纳米线薄膜从能量的角度来看是更有效的，与划痕几乎不可见的肉眼。我们发现，薄层电阻（R-S）的纳米线薄膜的增加，作为一个结果，将其划分为有限的几何形状和模拟数据的支持，我们预测在哪些长度尺度上，这种影响变得显着。我们的研究结果指出，使用这种纳米线系统作为替代更传统的技术在触摸传感器设计的可行性，同时突出了一些需要解决的挑战。(C)2016爱思唯尔有限公司版权所有。
Silver nanowire networks emerged recently as a remarkable substitute for indium tin oxide (ITO) transparent electrodes. Here we show that this silver nanowire alternative can be successfully processed using the same laser ablation technique commonly used to manufacture ITO devices. As a proof of concept, we have manufactured a fully operating five inch multi-touch highly-pixelated sensor typically used in smart phone technology and find it to perform comparably to one based on ITO. We observe that laser processing silver nanowire films is much more efficient from an energy point of view, with scribes hardly visible to the naked eye. We find that the sheet resistance (R-S) of the nanowire films increases as a result of dividing it into finite geometries and supported by simulation data, we predict over which length scales this affect becomes significant. Our results point to the viability of using such nanowire systems as an alternative to more traditional technologies in touch sensor design while highlighting some of the challenges to be addressed.
