Advances in Polymeric Nanofiber Manufacturing Technologies

Nanofibers continue to be one of the major success stories of nanotechnology. Whereas the definition of nanofibers according to National Science Foundation is that the diameters have to be less than 100nm, in the textile trade, fibers less than one micron in diameter are treated as nanofibers. It has been a challenge to produce fibers of less than one micron for a long time, and in major applications such as in filter media, submicron fibers, especially in the range of 500nm have been demonstrated to be more effective than fibers of less than 100nm.
