In this work, plasticized spinning PAN fibers were treated at low carbonization temperature for the first time. The properties of treated fibers were characterized by elemental analysis (EA), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) respectively. The SEM results show that cross section of the pre-carbonized fibers is circular with no apparent skin-core...
The effect of the spinning speed on structural and thermal properties of polyacrylonitrile (PAN) fibers prepared by plasticized spinning was investigated. The PAN fibers were characterized by scanning electron microscopy, X‐ray diffraction, differential scanning calorimetry, and thermogravimetric analysis. We found that the surface morphology of the fibers was relatively smooth. The presence of a...
