Abstract:

The conventional electrospun non-woven membranes have chaotic microstructure and inferior mechanical properties, which limit their applications. However, aligned nanofibers possess anisotropic morphology, anisotropic wettability, higher mechanical properties, and these advantages endows aligned nanofibers wider range of applications. Hence, many researchers modified conventional collecting apparatus to fabricate aligned nanofibers. In this paper, the methods and collecting equipments including rotating cylinder, parallel plate, auxiliary electrodes and some other apparatus was summarized, and the merits and demerits of these methods were also analyzed and compared, thus providing a reference for the further development of aligned nanofiber and expanding of the application of nanofibers.

Key words: electrospinning, aligned nanofiber, preparation method, auxiliary electrode
