将纳米Fe_3O_4磁性颗粒加入到N,N-二甲基甲酰胺(DMF)和氯仿溶解聚己内酯(PCL)的聚合物溶液中,通过静电纺丝制备PCL/Fe_3O_4磁性复合纳米纤维。利用扫描电子显微镜、X射线衍射仪、红外光谱仪、差示扫描量热分析及磁性演示对复合纤维的形貌尺寸、化学结构、热稳定性和磁性进行了表征。结果表明:所制得的磁性纳米纤维成型良好,且Fe_3O_4磁性颗粒分散在纳米纤维中,其与PCL是物理复合,复合纳米纤维具有一定的磁性,为PCL磁性复合纳米纤维的实际应用做了有益的探索研究。
The nano-Fe 3 O 4 magnetic particles were added to the polymer solution of N, N-dimethylformamide (DMF) and chloroform-soluble polycaprolactone (PCL) to prepare PCL / Fe 3 O 4 magnetic composite nanofibers by electrospinning. The morphology, chemical structure, thermal stability and magnetic properties of the composite fibers were characterized by scanning electron microscopy, X-ray diffraction, infrared spectroscopy, differential scanning calorimetry and magnetic properties. The results show that the prepared magnetic nanofibers are well shaped and the magnetic particles of Fe_3O_4 are dispersed in the nanofibers. The magnetic nanofibers are physically composited with the PCL. The magnetic nanofibers have certain magnetic properties and are beneficial to the practical application of the PCL magnetic nanofibers Exploring research.
