AB - Here we show an intriguing phenomenon in the bubble electrospinning process  that the ruptured film might be stripped upwards by an electronic force to  form a very thin and long plate-like strip, which might been received in the  metal receiver as discontinuous backbone-like wrinkled materials, rather than  smooth nano-fibers or microspheres. The processes are called the bubble  electrospinning. The electronic force can be replaced by a blowing air, and  the process is called as the blown bubble spinning. We demonstrate that the  size and thickness of the ruptured film are the crucial parameters that are  necessary to understand the various observations including beads and  nanoporous materials. We identify the conditions required for a ruptured film  to form discontinuous structure, and a critical width of the ruptured film to  form a cylindrical fiber, above which a long and thin plate-like strip might  be obtained, and a criterion for oscillatory jet diameter, which leads to  bead morphology of the obtained fibers. The space of the adjacent beads  depends on the fiber size. We anticipate our assay to be a starting point for  more sophisticated study of the bubble electrospinning and the blown bubble  spinning and for mass-production of both nanofibers and nanoscale  discontinuous materials.
