摘要:

采用溶胶-凝胶过程和静电纺丝技术相结合方法, 以聚丙烯腈和醋酸锰为前驱物, 制得了PAN/Mn(CH3COO)2复合纳米纤维. 将该复合纤维高温煅烧, 获得了Mn2O3纳米纤维. 采用扫描电镜(SEM)、红外光谱(FTIR)、差热-热重(TG-DTA)和X射线衍射(XRD)分析等对样品进行了表征. 结果表明, Mn2O3纳米纤维为规则的一维结构, 直径分布均匀, 具有铁磁性-反铁磁性-顺磁性相互转化的特性.

Abstract:

PAN/Mn(CH3COO)2 composite fibers were synthesized via sol-gel process combined with electrospinning technology, using polyacrylonitrile and manganese acetate as precursors. After high temperature calcination, Mn2O3 nanofibers were successfully prepared. The samples were characterized by scanning electron microscopy(SEM), fourier transform infrared(FTIR) spectroscopy, thermogravimetry-differential thermal(TG-DTA) and X-ray diffraction(XRD) analyses, respectively. The results show that Mn2O3 nanofibers have one-dimensional structure with uniformly distributed diameter. Magnetic property measurements suggested that the Mn2O3 nanofibers exhibited ferromagnetic-anti-ferromagnetic-paramagnetic property.
