柔性透明电极对触摸屏、平板显示器和太阳能电池技术至关重要。虽然碳纳米管网络电极前景光明，但分散性差的特点限制了它们的实用性。我们报告说，在纳米管分散体中加入少量共轭聚合物，可以通过旋转涂层和同时调整束大小和密度等参数，直接制造均匀的网络电极。经亚硫酰氯处理后，电极具有与迄今为止报道的其他基于碳纳米管的透明电极相竞争的片电阻。
Flexible transparent electrodes are crucial for touch screen, flat panel display, and solar cell technologies. While carbon nanotube network electrodes show promise, characteristically poor dispersion properties have limited their practicality. We report that addition of small amounts of conjugated polymer to nanotube dispersions enables straightforward fabrication of uniform network electrodes by spin-coating and simultaneous tuning of parameters such as bundle size and density. After treatment in thionyl chloride, electrodes have sheet resistances competitive with other reported carbon nanotube based transparent electrodes to date.
