High voltage at 20kV to 40kV will be applied to a spinneret and polymer solution jet will be injected to a collector when electrical attraction exceeds surface tension of polymer solutions.  Solvents in jets are gradually volatilized and jets will reduce to nanometer level when they reach a collector. Fig. 2 Electrospun nanofibers forms membranes shown in Fig. 2. Orientations of fibers depend on a collector.Nanofiber membranes are known that its total surface area per volume is much more than that of micrometer-size fiber membranes.
