REVIEW ON FIBER MORPHOLOGY OBTAINED BY BUBBLE ELECTROSPINNING AND BLOWN BUBBLE SPINNING

Abstract

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