| Abstract: | The micro-coiled carbon nanofibers are synthesized on the graphite substrate by chemical vapor deposition method. The results demonstrate that the regular single micro-coiled carbon nanofibers with diameter about 1 -2 μm and the double micro-coiled carbon nanofibers with diameter about 2 -5μm have been successfully prepared by deposition of acetylene using Ni as catalyst. Raman and XRD analysis indicates that the micro-coiled carbon nanofibers are composed of the minute graphitic crystalloid. Furthermore, the electromagnetism property of the micro-coiled carbon nanofibers is measured by wave-guide method in the frequency range of 8.2 -12. 4GHz. |
