Aligned nanofibers could be prepared by magnetic-field-assisted electrospinning(MFAES) of which matching relations between the parameters was rarely studied. In this paper

based on the orthogonal design

four main technological parameters which influence the preparation of PAN fibers through MFAES was optimized and screened at three levels

including solution concentration

the distance between two magnets

spinning voltage and flow rate. Taking fiber diameter size、distribution and degree of fiber alignment as study objects

by means of range analysis and variance analysis

the effect of the interaction between any two factors of solution concentration

the distance between two magnets and spinning voltage have also been studied. The effect of above parameters are as follows : solution Concentration is a highly significant affecting factor on fiber diameters and uniformity

the interaction effect between solution concentration and spinning voltage is a significant affecting factor on fiber uniformity

spinning voltage is a significant affecting factor on fiber ordering.
