采用一种结合加热的简单、快速的分散方法，以最小的缺陷分散长(大于10μm)单壁碳纳米管(SWCNTs)。该方法只需三个步骤：(1)加入分散剂，(2)加热，(3)研磨，即可在10分钟内制备出单壁碳纳米管的分散溶液。分散法不需要超声作用，会使单壁碳纳米管变短，并会产生表面缺陷。用该分散溶液制备了单壁碳纳米管薄膜，薄膜的电阻率为380TΩ/sq，透明度为64.8%。这种分散方法易于放大，可用于商业和工业应用的分散单壁碳纳米管的制备。
A simple and fast dispersion method that incorporates heating is used to disperse long (more than 10 μm) single-walled carbon nanotubes (SWCNTs) with minimal defects. The method enables a dispersed solution of SWCNTs to be produced in less than 10 min in only three steps: (1) addition of the dispersant, (2) heating, and (3) grinding. The dispersion method does not require sonication, which shortens the SWCNTs and can generate surface defects. SWCNT films were prepared from the dispersed solution, and the films exhibited a resistance of 380 Ω/sq at a transparency of 64.8%. This dispersion method can be easily scaled up, making it useful for the preparation of dispersed SWCNTs for commercial and industrial applications.
