Polyacrylonitrile (PAN)/N,N-dimethylformamide (DMF) solution was used as raw material to prepare nanofibers through electrospinning method.Focusing electrode was used as the collecting device.Suspended electrospun fibrous assembly can be obtained with a high degree of alignment through the process.Effects of solution concentration,number of stainless steel bar,collecting distance,flow rate and rotation speed of electrode on the degree of alignment of fibrous assembly were studied.Results showed that aligned fibers can be obtained through collecting electrodes with both four and six stainless steel bars.Degree of alignment for the obtained fibers increases with the increase of solution concentration.Medium collecting distance is more suitable for the alignment of fibers.Fibrous array with a high degree of alignment can only be prepared at relatively low flow rate and voltage.Rotation of collecting electrode can deteriorate the alignment of fibers.
