This paper observed wave-like beads with average size of 40 nm on the surface of nanofibers obtained by the blown bubble spinning. Theoretical analysis demonstrates that some perturbed waves are produced on the surface of the moving jets before solidification. The resultant fibers have many potential applications in water/ air filtration.
