ABSTRACT:
A process of making conductive polymeric fibers by electrospinning fibers from a blend of polymers dissolved in an organic solvent includes generating a high voltage electric field between oppositely charged polymer fluid in a glass syringe (4) with a capillary tip (5) and a metallic collection screen (2) and causing a polymer jet (3) to flow to the screen (2) as solvent evaporates and collecting fibers on the screen (2).
