| 摘要: 采用化学气相沉积法(CVD)，以二甲苯为碳源，二茂铁为催化剂，在涂有SiO2薄膜的不锈钢基底上，原位制备出了碳纳米管宏观条带。使用扫描电子显微镜(SEM)、透射电子显微镜(TEM)和拉曼光谱(Raman)对样品形貌和结构进行了表征。结果显示：合成的碳纳米管条带宽度为20～100 μm，厚度10～30 μm，长度可达6 mm；条带由大量多壁碳纳米管沿轴向密实排列组成。对其形成机制进行了初步探讨。 |

| Abstract: Macroscopic carbon nanotube ribbons have been synthesized by a Chemical Vapor Deposition(CVD) method. Xylene was used as the carbon source and ferrocene as the catalyst, stainless steel sheets coating with a thin SiO2 film were taken as growth substrates. The ribbons are about 20～100 μm wide, 10～30 μm thick and their length over 6 mm in 6 hours. Each ribbon consists a large amount of very clean multi-walled carbon nanotubes(MWNTs). The carbon nanotubes align along the direction in length. Scanning electron microscopy(SEM), transmission electron microscopy(TEM) and Raman analysis were used to evaluate the morphological and structural features of such nanotube-based material. The formation mechanism of ribbons is discussed. |
