This study proposes making polyethylene oxide (PEO) and water-soluble chitosan (WSC) nanofiber membranes via electrospinning. PEO/WSC mixtures are evaluated in terms of viscosity and conductivity, and are then electrospun into PEO/WSC nanofiber membranes using different voltages. Scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR) are performed to examine the structure of the nanofiber membranes. The test results indicate that a combination of a voltage of 20kV and a PEO/WSC ratio of 70:30 can form complete electrospun nanofibers. In addition, increasing the viscosity of the PEO/WSC mixtures can decrease the amounts of beads in the nanofibers.
