Abstract: |
Nanofibers can be widely used to prepare a variety of materials, such as filter materials, biosensors, protective coating for military suits, three-dimensional tissue scaffolds, composite reinforcement, drug carrier, wound dressing and electronic devices due to their high specific surface area, and small pores generated among nanofibers in the end products. Electrospinning is an efficient method for massively manufacturing nanofibers, nano-thin film materials. In this paper, the basic mechanism of massive electrospinning technology, including multi-needle electrospinning and needle-less electrospinning are discussed. The interference among needles/nozzles has been a barrier to realize massive production of nanofibers via multi-needle electrospinning technology. The influence from different arrangement/configurations of the needles, the characteristics and applications of the eletrospun products are also analyzed. In needle-less electrospinning process, the key problem is how to generate surface disturbance in the polymer solution or polymer melt. The principles and characteristics of the generation of magnetic field disturbance, bubble disturbance, spinning solution disturbance on the surface of the rotating spinning electrode, spinning solution disturbance on the surface of rotating disk electrode and massive production of electrospun fibers via porous tubular spinning head are summarized and compared.
