A study of free surface electrospinning process to enhance and optimize the nanofibre production

Electrospinning is a simple and inexpensive process that produces continuous nanofibres from the submicron diameter scale down to the nanometer diameter scale through an electrically charged jet of polymer solution. Previously, most of the electrospinning experiments have been carried out using single-needle arrangements. However, the low fluid throughput in needle spinning has limited the industrial use of needle schemes. In this research, a centrifugal electrospinning scheme was developed to produce non-woven webs of continuous nanofibres from polymer solutions. The system was optimized to enhance the production rate with controlled morphology and size of nanofibres.
