Summary In this study, we used a facile approach to examine the evolution of fiber morphologies during electrospinning, via solidifying the newly electrospun polyacrylonitrile (PAN) nanofibers in an ethanol bath at different electrospinning distances (2 cm to 10 cm). It has been observed that a massive jet-thinning took place at the initial stage of whipping instability, followed by uneven fiber-stretching. The fiber-stretching at the later whipping stage was mainly concentrated on beaded fiber sections, which improved the uniformity of the resultant fibers.
