Polymeric fibers with nanometer-scale diameters are produced by electrospinning. When the electrical<br/> forces at the surface of a polymer solution or melt overcome the surface tension then electrospinning occurs.<br/> Polyethylene oxide (PEO), Polycarbonate have been electrospun in our laboratory. Electrospun fibers are<br/> observed by optical microscopy or scanning electron microscopy. The average diameters of the electrospun<br/> fibers range from 300 nm to 30 nm when the electric field strength increasing from 1 kV/cm to 3 kV/cm.<br/> The average diameters of the electrospun fibers range from 200 nm to 30 nm when the concentration<br/> decreasing from 10 wt% to 4 wt%.
