随着平坦化方向的切换，碳纳米管的平坦化导致形成纳米四面体/纳米取向结构。在这项研究中，行为的个别碳纳米四面体/纳米结构下的拉伸载荷观察通过原位扫描电子显微镜使用微操纵器。由拉伸载荷引起的断裂的位置不一定在纳米四面体/纳米取向体接合处。结果表明，在拉伸载荷下，纳米四面体/纳米晶结不是力学薄弱点，纳米四面体/纳米晶结构与简单的多壁碳纳米管一样坚固.此外，纳米结构保持它们的形状并且不转变成管状形式。
Flattening of a carbon nanotube with a switching of the flattening direction results in the formation of a nanotetrahedron/nanoribbon structure. In this study, behavior of individual carbon nanotetra-hedron/nanoribbon structures under a tensile load is observed by means of in-situ scanning electron microscopy using micro-manipulators. Positions of breakage caused by a tensile load are not necessarily at a nanotetrahedron/nanoribbon junction. The results indicate that the nanotetrahedron/nanoribbon junctions are not mechanical weak points under a tensile load, and the nanotetra-hedron/nanoribbon structures are as strong as simple multi-walled carbon nanotubes. In addition, the nanostructures maintain their shape and do not transformed to a tubular form.
