P (AN-co-VDC) nanofibers are prepared through electrospinning. As for the processing parameters of electro-spinning, the effects on the morphology as well as diameter of nanofibers coming from solution concentration, spinning voltage and feed rate are investigated in details. The results show that the solution concentration affects the morphology and diameter of nanofibers mostly, and the spinning voltage and feed rate have relatively small impact. The uniform nanofibers with smooth surface and smaller diameter can be obtained when solution percent-age concentration is 20%, spinning voltage is 25 kV and feed rate is 0.63 mL/h.
