Abstract
Fabrication of polyvinyl alcohol (PVA) fibers loaded with evenly distributed nanosilver has been sucessfully done using electrospinner. The electrospinner is set at 15 kV DC voltage with distance between electrodes 13 cm, using a syringe hole diameter 0,5 mm. The feeding solution for the electrospinning was prepared by directly mixing the solution of PVA in water with a stable colloid of nanosilver at room temperature. The fibers morphology was characterized using scanning electron microscope. The optical property was tested using spectrometer. The distribution of silver nanoparticles in the fibers was tested using transmission electron microscope. The result indicates that the fibers still showing plasmonic property of silver having peak at 410 nm with no crystaline changes. The diameter of fibers loaded with nanosilver are smaller compared to that of the ones without nanosilver.The distribution of nanosilver in fibers made of PVA and the ones made of PVA and chitosan are compared and discussed.
