Bubble electrospinning and industrial production of nanofiber

In order to meet the requirements of rapid, efficient, stable and simple preparation of nanofibers, bubble spinning and the development of the bubble spinning were introduced in this paper, the research achievements of bubble spinning technology and various bubble spinning equipment′ s principle were reviewed, and the advantages and disadvantages of these bubble spinning was also discussed. Through in-depth analysis of the process and principle of bubble spinning, various improvement methods were put forward and a variety of different bubble spinning devices were obtained. Aming at resources saving and environmental protection requirements, the blown bubble spinning was developed, which is safer and more convenient to use air flow instead of high voltage. Due to meet industrial production, a novel bubble electrospinning equipment was developed, its output was ten times that of single needle electrospinning, the industrial production of bubble spinning nanofibers was realized. Soon the critical bubble electrospinning was put forwarded. The novelty method not only avoids the waste of resources but also greatly reduces the loss of energy when bubbles burst. It also further improves the efficiency of spinning. The practices show that the bubble spinning technology is a kind of spinning method with simple equipment, convenient operation, low cost, high production efficiency, wide applicability, and suitable for industrial production of nanofibers.
