Abstract:

Aiming at the technical problems in mass production of electrospun nanofibers, latest progress, key methods and core technology for increasing the output of electrospinning in recent years both at home and abroad were systematically introduced including two major types of mass production technology, i.e. , multi-needle and needleless spinning. The principle, structure and characteristics of various mass production methods were presented. Comparing from the perspective of industrial applications and academic research, respectively, a deep analysis on the advantages and disadvantages of the devices involved to promote the industrialization of nanofibers by electrospinning and the deep research of multi-functional nanofibers was made. The results show that needleless electrospinning has the advantages of uniform electric field and high yield, which will be the main direction of the development for mass production of electrospinning nanofibers, but further study should be focused no the spinning mechanism, simulation and industrial applications.

Key words: electrospinning, nanofiber, mass production, multi-meedle multi-jet, needleless multi-jet
