Fabrikasi Nanofiber PVA/Fe3O4 dengan Metode Elektrospinning

Abstract

. PVA/Fe 3 O 4 nanofibers are composite materials contain magnetic materials in nanometer-sized fibers that have biocompatible, non-toxic, and high chemical stability properties. Fe 3 O 4 will be composited with Polyvinyl Alcohol (PVA) and formed into nanofibers. The purpose of this study was to analize the effect of variations in volume % concentration of Fe 3 O 4 used on PVA/Fe 3 O 4 nanofibers. Fe 3 O 4 was dissolved in dionized water using ultrasonication. The suspension Fe 3 O 4 solution was mixed with 10% PVA solution to form PVA/Fe 3 O 4 solution with Fe 3 O 4 variations of 5%, 10%, 15%, and 20%. Electrospinning process was carried out on PVA/Fe 3 O 4 solution with a voltage of 20 kV, flow rate of 5 ml/hour, distance of jet to collector is 15 cm. The results of SEM characterization can be concluded that the one that has the best morphology in this study is PVA/Fe 3 O 4 nanofiber with a concentration of 10% because it generates uniform nanofibers with the smallest diameter at this concentration, the fibers do not attach to one other, and there are no beads.
