| Abstract: | Through adding a small amount of sulfur powder into solid ferrocene precursor,we fabricate high purity,uniform and straight carbon fiber arrays that can extend to several millimeters by the floating catalyst method.We also investigate the effect of sulfur and the reaction temperature in the synthetic process.The structure and morphology of the obtained carbon fibers are characterized by scanning electron microscopy(SEM) and transmission electron microscopy(TEM). |
| Keywords: | Carbon fiber Chemical vapor deposition Floating catalyst method Sulfur |
