Synthesis and characterization of exotic carbon fibers with branched spurs using nickel catalyst precursor

摘要：

　　In this paper,we have synthesized exotic carbon fibers with branched spurs by a chemical vapor deposition method using nickel catalyst precursor at 600 ℃.No catalyst particles were found at the base of the carbon spurs,suggesting that the nickel catalyst particles,which were decomposed from the nickel catalyst precursor,facilitated the growth of the carbon fibers but not the spurs.The formation of the spurs resulted from the fluctuation of the carbon source gas acetylene flow.The samples were characterized.by field emission scanning electron microscopy,transmission electron microscopy,and X-ray powder diffraction.
