The permalloy electroplating method was used to improve the electrical and magnetic properties of carbon fibers. For finding the appropriate conditions, we conducted the electroplating with different current densities. As a result of the SEM, we could observe that the number of particles is relative to the current density and irregular coating layers occur at higher current densities. Additionally, using EDS it was found that the compositions of Fe, Ni, and oxide are relative to the current density except the carbon. Therefore, it seems that there are many iron oxide and nickel oxide on the coating. The results of the electrical conductivity and vibrating sample magnetometer (VSM) revealed that the plated carbon fibers at high current density could show the typical soft ferromagnetism. Finally, the composition elements and current density can contribute to the electrical and magnetic properties of carbon fibers. |
