| 摘 要： | 采用化学共沉淀法制备纳米四氧化三铁,选用曲拉通X-100为分散剂,利用静电纺丝法制备PAN/Fe3O4磁性纳米复合材料。X射线衍射仪(XRD)验证了四氧化三铁在复合纳米纤维中的存在。同时使用扫描电镜(SEM)和透射电镜(TEM)对复合纳米纤维的微观形貌和Fe3O4在纤维中的分布进行了观察,利用热重(TGA)对纳米复合材料的热稳定性进行分析;通过磁性实验分析了纳米复合材料的磁性性能。结果表明,所制备PAN/Fe3O4磁性纳米纤维成型良好,且Fe3O4磁性颗粒在纤维中分散均匀,其与PAN是物理复合。纳米复合材料具有一定磁性,并可由磁性颗粒的加入量进行控制。

| Abstract: | Fe3O4 nanoparticles were fabricated by the chemical coprecipitation method,Triton X-100 was chosen as dispersant,PAN/Fe3O4 magnetic nanocomposites was fabricated through electrospinning.X-ray diffractometry(XRD) proved that Fe3O4 nanoparticles existed in nanocomposites.And the microstructure of composite nanofibers and magnetite(Fe3O4) nanoparticles’ distribution in fibers were characterized using scanning electron microscopy(SEM) and transmission electron microscopy(TEM).Thermogravimetry(TGA) was used to analysis the thermal stability of nanocomposites.The magnetic properties of Fe3O4 nanoparticles and nanocomposites were characterized using SQUID.The study showed that the morphology and formation of PAN/Fe3O4 nanofibers were favorable and Fe3O4 nanoparticles dispersed in fibers equably.It was physical combination between Fe3O4 nanoparticles and PAN.Nanocomposites were magnetic and changed by different contents of Fe3O4 nanoparticles. |
