Due to their unique properties, nanofibers have been widely used in various areas, for
example, information industry, pharmaceutical application, environmental industry, textile and
clothing, etc. Bubble electrospinning is one of the most important non-needle electrospinning methods
for nanofiber fabrication. It usually uses polymer bubbles for the production of nanomaterials by using
electrostatic force, flowing air or mechanical force to overcome the surface tension of bubbles. Bubble
electrospinning mainly includes bubble electrospinning and blown bubble electrospinning. History of
the development of bubble electrospinning is briefly introduced in this article, and the most promising
patents on the technology are elucidated. The methods of bubble electrospinning are single bubble
electrospinning, porous bubble electrospinning, blown bubble electrospinning, electrostatic-fieldassisted
blown bubble spinning and others. These different bubble electrospinning methods are also
discussed in this paper.
