Preparation and Characterization of Polyacrylonitrile-Based Nanofibers by Electrostatic Spinning
Abstract:
PAN and P(AN-co-MA) nanofibers have been successfully prepared by electrospinning. The mass concentration is 6%-12%, voltage of 15-25 kV, tip-to-collector distance is 25 cm. The morphology of the obtained samples was measured by a Scanning electron microscopy (SEM). The results showed that there were some large beads distributed on the PAN fiber skeleton when the spinning solution concentration is low. With the spinning solution concentration increased, the bead structure is gradually reduced. The fiber diameter increased with the concentration. For the synthetic reaction mixture P(AN-co-MA), it could obtain uniform nanofibers easily
