摘要：

Magnetic carbon composite nanofibres, using the mixed homogeneous solution consist of polyacrylonitrile (PAN), ferric acetylacetonate (AAI) and dimetbylformamide (DMF) as raw material, were prepared by electrospinning-calcination technology. TEM analysis showed that the carbon nanofibre diameter of sample CF900 was about 130-210 nm, in which magnetic nanoparticles were uniformly distributed. The magnetic properties of carbon composite nanofibres under different carbonization temperature was also investigated. Results showed that saturation magnetization (Ms) and remanent magnetization (Mr) increased with the increase of the temperature. When carbonization temperature was 900℃, the sample was of good magnetic property with high saturation magnetization (Ms=27.55 A·m2/kg). Moreover, the specific surface area (SBET) and total pore volume (Vtotal) were up to 354.0 m2/g and 0.315 mL/g, respectively.
