Electrospinning is a simple straight-forward means of fabricating nanoscale polymer fibers. Solution electrospinning is obtained on placing a droplet of the polymer solution in a high enough electric field to initially deform it into a Taylor’ cone and then draw it into a jet. The increased surface area generated due to fiber formation and extension drives the process. Continuing efforts in electrospinning technology are aimed at reducing the average fiber diameter (d) to well below 100 nm.
The technique has only been demonstrated for electrospinning poly(acrylonitrile) (PAN) from DMF solutions, but is likely to work as well with other polymer solutions. In this case, as the authors point out, the new technique can increase the productivity in electrospinning of polymer nanofibers.
