摘要

Electrospinning is a versatile and cost-effective technique for producing functional nanofibers from various polymers, blends, composites, ceramics, etc. Electrospinning is an electrohydrodynamic process which has lately become an exciting and versatile platform technology for the production of nanofibrous materials. The simplicity of the electrospinning setup and the relatively high production rate of nanofibers make this process highly attractive for both academia and industry. In electrospinning technique, a continuous filament is electrospun from polymer solutions (most common) or polymer melts (very limited) under a very high electrical field (Figure 1a) resulting in ultra-fine fibers (1000 times smaller than a single human hair) ranging from tens of nanometers to few microns in diameter (Figure 1b). Very briefly, the electrospinning process takes place between a spinning head (capillary opening (nozzle) or a rotating drum (nozzle-less)) and a collector counter electrode where a high voltage is applied (typical 10-30 kV) (Figure 1a). Electrospun nanofibers/nanowebs (Figure 1c) have several remarkable characteristics such as very large surface-to-volume ratio, high porosity within the nanoscale, unique physical and mechanical properties along with the flexibility for chemical/physical functionalization. The outstanding properties and multi-functionality of nanofibers/nanowebs make them favorable candidates in many areas including healthcare, filtration, textiles, energy, sensors, electronics, environmental, food, packaging, agriculture, etc.
