采用机械方法缩短碳纳米管（CNTs）以改善分散而不降低其导热性。单壁碳纳米管（SWCNTs）被机械切割成短而开放的富勒烯管。然后将这些缩短的SWCNTs用于聚合物复合材料。原子力显微镜和扫描电镜表征表明，纳米管的缩短显著改善了碳纳米管的分散。发现含有短CNTs的复合材料的导热性比含有原始CNTs的复合材料好得多。
A mechanical method was used to shorten carbon nanotubes (CNTs) for improving dispersion without reducing their thermal conductivity. Single walled carbon nanotubes (SWCNTs) were mechanically cut to produce short and open-ended fullerene pipes. These shortened SWCNTs were then used in polymer composites. Both atomic force microscopy and scanning electron microscopy characterizations suggested that nanotube shortening significantly improved CNT dispersion. Thermal conductivity of composites containing short CNTs were found to be much better than those containing pristine CNTs.
