摘要：
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.
