Polymeric nanofibers applied voltage

Electrospinning based on the application of a static electric field on a polymer solution or melt through a spinneret appears to be a simple and well-controllable technique able to produce polymeric nanofibers. A typical experimental setup is based on a capillary injection tip, a high-voltage source able to apply electric fields of 100-500 KVm , and a metallic collector, or counter electrode. Electric current in electrospinning experiments is usually in the order of a few milliamperes. ... 

Polymeric nanofibers can be made using the electrospinning process which has been described [20-35]. Electrospiiming, Figure 1 uses a high electric field to draw a polymer solution from tip of a capillary toward a collector. A voltage is applied to the polymer solution which causes a jet of the solution to be drawn toward a grounded collector. The fine jets dry to form polymeric fibers which can be collected as a web.
