Nonwoven mats and polymeric fibers of
diameter as low as 50 nm can be
produced by electro spinning technique.
In this process, a fiber is formed from
electrically charged polymeric liquid jet in
presence of an externally applied electric
field that accelerates the charged liquid
jets. Subsequently, jet stretching and
solvent evaporation during the travel of
the liquid jets yield the fibers. Fibers with
varying alignment can be obtained by
modifying the collector design.
