Popis: | Fiber mats with average fiber diameter ranging between 80 and 250 nm of polyvinyl alcohol (PVA)/water solution having a concentration of 4 wt.% have been prepared by electrospinning method. The influence of applied voltage, flow rate, and needle-to-collector distance on the fiber morphology and diameters has been studied. Scanning electron microscopy and atomic force microscopy are used to characterize the fibers. It has been observed that bead-free fibers of 4 wt.% PVA can be obtained at lower voltages (9 kV). Also, density and the deposition area of the fiber mats showed a clear dependence on the applied voltage, flow rate, and collector distance. |
