利用一种简单的方法将单壁碳纳米管组装成无限长的带状和纤维状。该工艺包括将纳米管分散在表面活性剂溶液中，在聚合物溶液的流动中重新凝聚纳米管以形成纳米管网，然后将该网整理成纳米管纤维。流动诱导的排列可以导致纳米管在具有带状形式的网格中的优先取向。与传统的碳纤维不同，纳米管纤维可以强烈弯曲而不会断裂。它们所获得的弹性模量比高品质布基纸的模量高10倍。
A simple method was used to assemble single-walled carbon nanotubes into indefinitely long ribbons and fibers. The processing consists of dispersing the nanotubes in surfactant solutions, recondensing the nanotubes in the flow of a polymer solution to form a nanotube mesh, and then collating this mesh to a nanotube fiber. Flow-induced alignment may Lead to a preferential orientation of the nanotubes in the mesh that has the form of a ribbon. Unlike classical carbon fibers, the nanotube fibers can be strongly bent without breaking. Their obtained elastic modulus is 10 times higher than the modulus of high-quality bucky paper.
