摘要：Lignin of cornstalk and PAN were used as raw materials to prepare lignin-based carbon nanofibers by means of electrospinning technique at 15 kV voltage, 0.04 mm/min pushing speed and 12 cm receiving distance. The precursor of carbon nanofibers prepared was oxidized at 200 to 300°C and carbonized at 600 to 700°C so as to prepare lignin-based carbon nanofibers. After carbon nanofibers were characterized, it was found that lignin-based carbon nanofibers obtained at 900°C was of uniform diameter, high smoothness, good form, the highest structural compactness, the least structural defects, and high thermal stability. All lignin-based carbon nanofibers were graphitized to a low extent and show a tur- bostratic graphite structure.
