“…centrifugal force) to overcome the surface tension of bubbles, including the bubbleelectrospinning [3][4][5][6][7][8][9][10], blown bubble spinning [11,12], membrane spinning [13,14] and others. Before introduction to the new technology, we begin with electrospinning [15][16][17][18][19], which is the simplest way to producing ultrafine fibers with diameters ranging from 10 m  down to 10nm by forcing a viscous polymer solution or melt through a spinnerette with an electric field. When the electric force overcomes its surface tension of the Taylor cone, a charged jet is formed.…”

Bubbfil spinning is to use polymers' or melts' bubbles or membranes for fabrication of nanomaterials including smooth nanofibers and discontinuous nanofibers by using electrostatic force, blowing air or mechanical force to overcome the surface tension, it mainly includes the bubble-electrospinning, blown bubble spinning and membrane spinning. The initial ejecting velocity of the Bubbfil spinning process is as high as 100 meters per second. A history of the development of Bubbfil spinning is briefly elucidated, its main properties are emphasized, some effective modifications are discussed for different applications including single bubble electrospinning, blown bubble spinning, air-jet assisted bubble electrospinning, electrostatic-field-assisted blown bubble spinning, and vibration bubble electrospinning which is suitable for melts or high-concentration solutions. Morphology properties are also discussed for different applications.

“…Also, methods for directly producing nanofibers are rapidly developed for meeting the various requirements and applications [4][5][6][7]. Among these approaches electrospinning shows its great potential on fabrication of nanofibers as a simple and effective way [8][9][10]. However, low throughput from electrospinning limits its large-scale development in industry which prompts new techniques to overcome this problem with some modifications [11][12][13][14].…”

Effect of solution concentrations on the morphology of nylon6/66 nanofibrous yarns by blown bubble-spinning

et al. 2014

In this paper, a novel method called blown bubble-spinning was employed to produce nanofibers. Compared with the traditional technologies, such as melt blowing and electrospinning, hot airflow is used in blown bubble-electrospinning to overcome the surface tension of the polymer bubbles and to pull multiple jets from the broken bubble into nano scale ones which are solidified to nanofibers after solvent evaporation, the technology requires no electrostatic force. The effect of Nylon6/66 polymer concentration on the morphology of nanofibers is investigated. The results indicate that nanofibers without beads were successfully fabricated under this one-step process and spontaneously aggregated to form superfine fiber assemblies. Besides, average diameters of both fiber assemblies and inner nanofibers increased with polymer concentrations, ranging from 6 micrometers to 34 micrometers and 180nm to 524nm, respectively. This study provides a promising approach to directly generate fiber assemblies composed of nanofibers, which may show great potential in the future applications.
