摘要：

Micro-coiled carbon fibres were prepared by the impurity metal-activated pyrolysis of acetylene containing a small amount of thiophene. The growth conditions and catalytic effect of the metal impurities were examined. Of the various metals, Ni, Ti and W were the most effective for the growth of the coils. In the case of Ni metal impurity, it was considered that Ni3C single crystallites present in the tip part of the coils have a catalytic effect on the coiling of the carbon fibres.
