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(CH_3COO)_2复合纳米纤维. 将该复合纤维高温煅烧, 获得了Mn_2O_3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, Mn_2O_3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.

PAN/Mn(CH_3COO)_ 2 composite fibers were synthesized via sol-gel process combined with electrospinning technology, using polyacrylonitrile and manganese acetate as precursors. After high temperature calcination, Mn_2O_3 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 Mn_2O_3 nanofibers have one-dimensional structure with uniformly distributed diameter. Magnetic property measurements suggested that the Mn_2O_3 nanofibers exhibited ferromagnetic-anti-ferromagnetic-paramagnetic property.
