摘要：

The coiled/straight carbon nanofibers (CNF) were synthesized using catalytic chamical vapor deposition. Cobalt acetate tetrahydrate was used as a catalyst with magnesium oxide as support, for synthesizing CNFs. Submicron sized Ni powder was chosen as catalyst, for the synthesis of carbon nanocoiled fibers (CNC). It was found that the larger the anisotropy, the greater the degree of coiling/twisting and the coil diameter and smaller the anisotropy, the smaller the degree of coiling/twisting and the coil diameter.
