【Abstract】 Preparation of polyacrylonitrile(PAN) nanofibers via electrospinning was reported in the literature, in which diameter of the nanofibers ranged from 500 to 1 000 nm. We investigated the effect of processing parameters, such as solvent types, solution mass fraction, spinning angle, and molecular weight on morphology and diameter of the PAN nanofiber in detail. The results showed that ultrafine PAN nanofiber with an average diameter of 20 nm could be obtained by adjusting the electrospinning parameters.
