Abstract

Very fine polypropylene (PP) fibers were made from molten PP in vacuum using an electrospinning process. Under the influence of a modest external electric field, a droplet of PP melt was pulled out, trailed by a jet that became thin and soon broke. When the electric field strength was increased, a steady charged jet flew toward a collector. Jets solidified to form fibers either in flight or after reaching the collector. The semi-angle of the Taylor cone from which the jet emerged was about 37.5 ± 2 o. The diameters of the fibers ranged from 300 nanometers to 30 microns. Scanning electron micrographs showed a variety of fiber morphologies, including coils indicating that the charged jet developed an electrically driven bending instability.
