采用红外辐射加热系统对氢气放电制备的多壁碳纳米管（MWNT）进行纯化。利用扫描电子显微镜、高分辨率透射电子显微镜、X射线衍射仪和拉曼光谱仪研究了纯化的MWNT的形貌、结构、振动模式和晶体完整性。此外，使用微操纵器系统使用双探针方法测量单个纯化的MWNT的电导率。事实证明，MWNT具有高度石墨化、沿长轴的电导率约为1.85X10(3) S cm(-1)，以及超过10(7) A cm(-2)的巨大电流密度。 (C) 1999 Elsevier Science Ltd. 保留所有权利。
Multiwalled carbon nanotubes (MWNTs), which were prepared by hydrogen are discharge, were purified by using an infrared radiation heating system. The morphology, structure, vibrational modes and crystalline perfection of purified MWNTs were investigated by using scanning electron microscopy, high-resolution transmission electron microscopy, an X-ray diffractometer and a Raman spectrometer. Moreover, the electrical conductivity of individual purified MWNTs was measured using a two-probe method using a micro manipulator system. It turned out that the MWNTs had a high degree of graphitization, an electrical conductivity of about 1.85X10(3) S cm(-1) along the long axis, and an enormous current density of more than 10(7) A cm(-2).
