以聚丙烯腈(PAN)、乙酰丙酮铁(AAI)、N, N-二甲基甲酰胺(DMF)为原料,采用静电纺丝-煅烧技术成功制备出磁性碳纳米复合纤维。通过TEM分析发现CF900的直径约为130~210 nm,磁性纳米颗粒均匀地分散在碳纳米纤维中,并探讨了碳化温度对碳纳米复合纤维磁性能的影响。结果显示：饱和磁化强度(Ms)和剩余磁化强度(Mr)均随温度的升高而增大,样品 CF900的饱和磁化强度(Ms)高达27.55 A·m2/kg,比表面积(SBET)和总孔容积(Vtotal)达354.0 m2/g和0.315 mL/g。
Magnetic carbon composite nanofibres, using the mixed homogeneous solution consist of polyacryloni-trile (PAN), ferric acetylacetonate (AAI) and dimetbylformamide (DMF) as raw material, were prepared by elec-trospinning-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 car-bon 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.
