Nano-to-micro-structured biodegradable polycaprolactone (PCL) fabrics were prepared by electro spinning of PCL solutions in 9~16 % (w/v). Electrospun microfiber fabrics were obtained using methylene chloride, chloroform, dichloroethane, dimethylformamide (DMF), n-hexane and methanol as solvents. The fiber morphology was observed under a scanning electron microscope and the effects of the instrument parameters, including electric voltage, flow rate, and solution parameters, such as concentratino and solvent, were examined. At high voltage (above 10 kV), the electrospun PCL fibers exhibited a broad diameter distribution and the morphology of the structure could be changed by changing the flow rate. With increasing solution concentration, the morphology changed from beaded fibers to uniform fibers. We also found that using a non-solvent allowed the solution viscosity and the thickness of the electrospun fibers to be controlled.
