在此详细研究了碳纳米管的润湿性和毛细作用。纳米管并非“超级吸管”，尽管它们能够被表面张力较低的物质（如硫、硒和铯，其表面张力上限小于每米200毫牛顿）润湿和填充。这一上限意味着典型的纯金属不会通过毛细作用被吸入纳米管的内腔，而水和有机溶剂则会。这些结果对于在纳米尺度的实验中进一步使用碳纳米管具有重要意义。
The wetting and capillarity of carbon nanotubes were studied in detail here. Nanotubes are not ''super-straws,'' although they can be wet and filled by substances having low surface tension, such as sulfur, selenium, and cesium, with an upper limit to this tension less than 200 millinewtons per meter. This limit implies that typical pure metals will not be drawn into the inner cavity of nanotubes through capillarity, whereas water and organic solvents will. These results have important implications for the further use of carbon nanotubes in experiments on a nanometer scale.
