When a polymer bubble is broken in the bubble electrospinning process, thousands of thousands jets are produced with almost same initial ejecting speed, which plays a very important role on the formation of the nanofiber. In this paper, the nanofiber membranes were prepared by the bubble spinning with different air temperatures. This paper also gives a simple mathematical model to predict the initial speed of jets, and it is as high as 300 m/s.
