Frequency of Bubble Formation in Modified Bubble Electrospinning

Bubble-electrospinning is one of the most straightforward ways to fabricate polymer solution into nanofibers. The key point of the technology is to control bubble size and formation frequency. A modified bubble electrospinning set-up is designed to control the size of polymer bubbles and frequency of bubble formation in the spinning process. A PVA (10wg %) solution is used in the experiment for fabricate polymer solution into nanofibers and superfine nanofibers are obtained with the average diameter of about 200nm.
