Abstract

Abstract Carbon nanofibers with the distribution of magnetic Ni metal (Ni-CNFs) have been synthesized using Nickel (II) acetate tetrahydrate (Ni (OCHCH3)2.4H2O), polyacrylonitrile (PAN) as precursors by electrospinning technique. The as-prepared nanofibers were dried in a vacuum oven, stabilized, and followed by carbonization at 850 °C in N2 atmosphere. Their structural phase composition, microstructure, and magnetic properties have been investigated. The phase formation of pure Ni-CNF without any impurity has been confirmed by X-ray diffraction (XRD) pattern. The average diameter of the nanofibers and the Ni nanoparticles has been calculated to be 159±25.72 nm and 67±11.24 nm, respectively. Energy-dispersive X-ray spectroscopy (EDX) measurement has been carried out to confirm the presence of Ni and C elements with their weight%. Raman spectrum attributes the presence of two characteristic absorption peaks of carbon materials. Room temperature (300 K) magnetic measurement shows the ferromagnetic behavior of Ni-CNF. These nanofibers have the potential to be used in a wide variety of applications including These materials have wide variety of applications as in different magnetic devices (magnetic sensors, magnetic recording devices, and soft magnetic materials.), microwave absorption materials, supercapacitors and batteries etc.
