The morphology and structure of micro-coiled carbon nanofibers were characterized by SEM, Raman spectrum and microscopy. The micro-coiled carbon nanofibers with regular shape and high purity was prepared. The effects of process parameters such as reaction time and the electroplating time on the structure of micro-coiled carbon nanofibers were studied by experiments. At last, the electromagnetic performance of the micro-coiled carbon nanofibers was measured to demonstrate their wave ab-sorbing ability by wave-guide in the frequency range of 8.2~12.4GHz.The results showed that the micro-coiled carbon nanofibers with the good elec-tromagnetic property were successfully prepared on the electroplating nickel film.
