摘要
分形学体现了科学与美学的完美结合,在众多领域得到了广泛的应用。该文提出了碳纳米管束的分形结构,并将该结构应用于碳纳米管的储氢问题。研究表明,分形碳管束的储氢体积密度高于普通碳管束,并且,通常只需要1级分形结构就可以得到较好的储氢性能。此外,该文通过对不同分形形式的比较,发现内部包含七个碳管的分形结构的储氢性能最优。
Fractal represents the integration of mathematics and aesthetics, and has been widely used in many fields. The bundle of carbon nanotubes with the fractal character is proposed in this paper, and is applied to hydrogen storages. It is shown that the fractal bundle of carbon nanotubes provide a higher hydrogen storage than that of common bundles. The fractal bundle with only one hierarchal level of self-similarity usually provides the optimal volume density of hydrogen storages. And the fractal structure composed of 7 sub-structures is optimal for hydrogen storages.
