Abstract

The synthesis of starch nanofibers with the electric spinning technique produces nanofibers with high porosity characteristics, a very high specific surface area, and biocompatible, biodegradable, and bioabsorbable properties. In this study, fiber synthesis was carried out by varying the voltage in the spinning process. The morphology of the formed fiber is cylindrical, with several beads formed. The size of the beads increases with increasing voltage. The voltages parameter produces an insignificant difference in diameter. The fiber diameter distributions obtained at voltages of 13, 15, and 17 kV were 1231.08+-11.59 nm, 1121.18+-273.28 nm, and 1082.54+-291.33 nm, respectively.
