Abstract: As a new method , bubble-electrospinning process to some extend is an effective way of mass production of nanofibers.However, comparing to other types of electrospinning methods, bubble-electrospinning is still a new topic in the production of nanofibers. This paper briefly introduces several types of electrospinning methods and discusses the basic principle of the bubble-electrospinning.Furthermore,the potential distribution of the bubble , bubble surface tension , bubble hierarchical ruptured for nanofiber fabrication and the bubble number are analyzed specifically. Focusing on the review of the rencent year’s researches and developments, the current met challenges and the research direction of electrospinning are summed up.

Key words: bubble-electrospinning, nanofiber, principle, polymer
