Electrospinning is a highly efficient technology for fabrication of a wide variety of polymeric nanofibers. However, the development of traditional needle-based electrospinning has been hampered by its low productivity and need of tedious work dealing with needles cleaning, installation and uninstallation. As one of the most promising needleless electrospinning means, bubble electrospinning is known for its advantages of high productivity and relatively low energy consumption due to the introduction of a third force, air flow, as a major force overcoming the surface tension. In this paper, the restrictions of conventional electrospinning and the advantages of needleless electrospinning, especially the bubble electrospinning were elaborated. Reports and patents on bubble-spun nanofibers with unique surface morphologies were also reviewed in respect of their potential applications.

电纺丝是用于制造多种聚合物纳米纤维的高效技术。然而，传统的基于针的静电纺丝的发展因其生产率低以及需要繁琐的针清洁，安装和拆卸工作而受到阻碍。作为最有前途的无针静电纺丝方法之一，由于引入了第三种力，即气流，作为克服表面张力的主要力量，气泡静电纺丝以其高生产率和相对较低的能耗而著称。本文阐述了常规静电纺丝的局限性以及无针静电纺丝的优势，尤其是气泡静电纺丝。
