Electrospinning process and applications of electrospun fibers

Abstract An electric field is used to create a charged jet of polymer solution. As this jet travels in air, the solvent evaporates leaving behind a charged fiber that can be electrically deflected or collected on a metal screen. Fibers with a variety of cross sectional shapes and sizes were produced from different polymers. The diameter of these fibers was in the range of 0.05 to 5 microns. This paper describes the electrospinning process, the processing conditions, fiber morphology, and some possible uses of electrospun fibers.
