Multi-Bubble Electrospinning of Nanofibers

Abstract:

Multi-bubble electrospinning is considered as one of efficient techniques which have potential for large scale production of nanofibers. However, there is a lack of published research to better understand the formation of bubbles and the mutual interference among these bubbles. In this paper, the formation methods of multiple bubbles on the free liquid surface were examined to determine which ones performed relatively well. The influence of solution concentration, applied voltage, gas pressure, liquid length and the shape of electrode on the process and morphology of nanofibers were also investigated. The results showed that multiple gas tubes in the solution was the best choice to produce stable multiple bubbles though the number of bubbles was less than that obtained by the other methods. Some important processing parameters, such as solution concentration, applied voltage and the shape of electrode, had an important influence on the morphologies of nanofibers. Finally, both experimental and theoretical investigations in this process proved that the mutual interference among bubbles existed during multi-bubble electrospinning process.
