Amplification of carbon nanotubes via seeded-growth methods
摘要：
The present invention is directed towards methods (processes) of providing large quantities of carbon nanotubes (CNTs) of defined diameter and chirality (i.e., precise populations). In such processes, CNT seeds of a pre-selected diameter and chirality are grown to many (e.g., hundreds) times their original length. This is optionally followed by cycling some of the newly grown material back as seed material for regrowth. Thus, the present invention provides for the large-scale production of precise populations of CNTs, the precise composition of such populations capable of being optimized for a particular application (e.g., hydrogen storage). The present invention is also directed to complexes of CNTs and transition metal catalyst precurors, such complexes typically being formed en route to forming CNT seeds.
摘要（中）：

本发明涉及提供大量具有规定直径和手性（即精确群体）的碳纳米管（CNT）的方法（方法）。 在这种方法中，预先选择的直径和手性的CNT种子生长到其原始长度的许多（例如，数百）倍。 随后可以将一些新生成的材料循环回种子材料再生。 因此，本发明提供了大规模生产精确的碳纳米管群体，能够针对特定应用（例如，氢存储）优化的这些群体的精确组成。 本发明还涉及CNT和过渡金属催化剂前体的复合物，这些络合物通常在形成CNT晶种途中形成。
