Abstract:
The polyacrylonitrile(PAN)-based fibers are carbonized at temperature of 600~900℃.Chemical composition and microstructure of the fibers are characterized using elemental analyzer,wide-angle X-ray diffractometer and laser Raman spectrometer.Mechanical and electrical properties of the fibers are examined.The results indicate that with the increase of the carbonization temperature,the mass fraction of carbon increases;nitrogen,hydrogen and oxygen are partially removed from the fibers;linear density and elongation at break of the fibers decrease,volume density and tensile strength of the fibers increase;electrical resistivity of the fibers decreases drastically due to the increasing volume fraction of turbostratic graphite structure formed in carbonization process;low-temperature carbonization fiber/resin composite coatings with admirable antistatic property can be prepared.
