| Abstract: | Ultrafine fibers of chitosan/poly(vinyl alcohol)/poly(vinyl pyrrolidone) (CS/PVA/PVP) were prepared via electrospinning. The
structure and morphology of CS/PVA/PVP ultrafine fibers was characterized by the Fourier transform infrared (FT-IR) spectroscope
and scanning electron microscope (SEM). Furthermore, the effects of the concentration of PVA, PVP and the electrospinning
voltage on the morphology of ultrafine fibers were investigated the the SEM. When the concentration of PVA was at the range
of 30wt%–40wt%, ultrafine fibers could be obtained. The diameter distributions of ultrafine fibers decreased when the electrospinning
voltage increased from 20 to 30 kV. The rough surface fibers could be obtained after etching with CHCl3. |
