Nanostructures grown on carbon cloth are recently attracted great interests for flexible field emitter and cold cathode. In this paper, we report high-aspect ratio ZnO nanowires grown on carbon cloth by a low-temperature solution chemical approach that can be used as a flexible and high performance cold cathode. The carbon cloth is covered by outward-grown ZnO nanowires uniformly and densely with spiny structures. The hybrid structures exhibits a turn-on electrical field of 4.36 V/microm and a field enhancement factor of 1157, which benefit from the high-aspect ratios of both ZnO nanowires and carbon cloth. These results demonstrate a low cost and scalable approach for flexible cold cathode lighting and field emission display.
最近，生长在碳布上的纳米结构因其在柔性场发射体和冷阴极方面的应用而备受关注。在本文中，我们报道了通过低温溶液化学方法在碳布上生长的高纵横比氧化锌纳米线，其可作为柔性高性能冷阴极。碳布被向外生长的具有刺状结构的氧化锌纳米线均匀且密集地覆盖。这种混合结构的开启电场为4.36 V/μm，场增强因子为1157，这得益于氧化锌纳米线和碳布的高纵横比。这些结果展示了一种用于柔性冷阴极照明和场发射显示的低成本且可扩展的方法。
