Herein, we have studied a structure of SWNT films doped by organic molecules. In this study, we reacted organic molecules with SWNT films by a vapor phase and a liquid phase, respectively. The structure of doped SWNT films was investigated using synchrotron X-ray powder diffraction measurements, and we found the clear difference between the vapor phase reaction (v-doped) and the liquid phase reaction (I-doped). In v-doped SWNT films, organic molecules are predominantly encapsulated inside SWNTs, although molecules adsorbed on the surface of SWNT bundles in l-doped SWNT films.
在此，我们研究了由有机分子掺杂的单壁碳纳米管（SWNT）薄膜的结构。在本研究中，我们分别通过气相和液相使有机分子与SWNT薄膜发生反应。使用同步加速器X射线粉末衍射测量对掺杂的SWNT薄膜的结构进行了研究，我们发现气相反应（气相掺杂）和液相反应（液相掺杂）之间存在明显差异。在气相掺杂的SWNT薄膜中，有机分子主要包裹在SWNT内部，而在液相掺杂的SWNT薄膜中，分子吸附在SWNT管束的表面。
