由碳纳米管制成的连续纱线的产生将使宏观纳米管器件和结构得以构建。在这里，我们表明，碳纳米管可以自组装成纱线的长度高达30厘米，简单地从超排列的碳纳米管阵列中拉出，这些纱线的强度和导电性可以通过在高温下加热来提高。我们的研究结果应该有助于将碳纳米管卓越的机械，电气和热性能转化为宏观尺度。
The creation of continuous yarns made out of carbon nanotubes would enable macroscopic nanotube devices and structures to be constructed,. Here we show that carbon nanotubes can be self-assembled into yarns of up to 30 cm in length simply by being drawn out from superaligned arrays of carbon nanotubes, and that the strength and conductivity of these yarns can be enhanced by heating them at high temperatures. Our findings should help to translate the remarkable mechanical, electrical and thermal properties of carbon nanotubes to a macroscopic scale.
