Abstract: Electrospinning is the one of the simplest and effective methods for producing nanofibers atpresent. However, low production capacity has been the bottleneck for its large-scale application. Over thepast few years, there have been lots of relevant researches on electrospinning, and many researchers designed multi-needle device and single-needle device to improve its productivity, but there are still many problems to be resolved. This article discussed the research progress and esisting problems of electrospinning technology in detail.

Key words: electrospinning; nanofiber; technological development
