| 摘 要： | 采用溶胶-凝胶过程和静电纺丝技术,以三氯化铁(FeCl3·6H2O)、醋酸钴(Co(CH3COO)2·4H2O)和聚乙烯醇(PVA)为前驱物,制得PVA/FeCl3/Co(CH3COO)2复合纳米纤维.经高温煅烧,制备了CoFe2O4纳米纤维.利用扫描电镜(SEM)、红外光谱(FT-IR)、差热-热重(TG-DTA)和X射线衍射(XRD)等分析测试手段对样品进行了表征,并研究了其磁性质.结果表明:静电纺丝技术制备的CoFe2O4纳米纤维为规则的一维结构,直径分布均匀,具有良好的铁磁性.

| Abstract: | PVA/FeCl3/Co(CH3COO)2 composite nanofibers were synthesized by using sol-gel processing combination with electrospinning technology,where polyacrylonitrile and manganese acetate were used as precursors.After high temperature calcination,CoFe2O4 nanofibers were successful prepared.The samples were characterized by scanning electron microscopy(SEM),fourier transform infrared(FT-IR) spectroscopy,thermogravimetry-differential thermal(TG-DTA) and X-ray diffraction(XRD) analysis,respectively.The results showed that CoFe2O4 nanofibers with one-dimensional structure had been prepared uniformly.And,magnetic property measurements suggested that the CoFe2O4 nanofibers exhibited ferromagnetic paramagnetic. |
