Abstract: A brief review of mathematical models of electrospinning is given. The nano-effect and electrospinning dilation are presented to explain how to prepare extremely high strength continuous nanotibers and nanoporous microspheres, respectively. According to the established models, vibration-electrospinning is introduced to improve electrospinability, Siro-electrospinning is suggested to mimic the spinning procedure of a spider and magneto-electrospinning is used to control the instability arising in the electrospinning process. A new theory linked to both classical mechanics and quantum mechanics should be developed to explain certain special phenomena in electrospinning. E-infinity theory is considered to be a potential theory to deal with …

Electrospinning is a simple but powerful method for making nanofibers that can then be collected to create porous mats. We expand the range of this technique by making nanofibers from macromolecules with a molecular weight of 3,000,000, namely poly(ethylene oxide) (PEO). Gelation of PEO blocks its spinning by traditional electrospinning. PEO was mixed with pure alcohol, and in specific concentration 10 wt % and under vibration condition, the mixed solution behaves like polymers for electrospinning, the average diameter of the obtained nanofibers is about 100 nm. © 2006 Wiley Periodicals, Inc.

Similar to the nuclear age, the so-called nanoage is coming, the growing gap between nano haves and nano have-nots, however, will remain, as has global competition, particularly from the electrospinning technology.
