Fabrication of Polyvinylpyrrolidone/Boehmite Nanofibers by Electrospinning

Abstract

Polyvinylpyrrolidone (PVP)/boehmite nanocomposites fibers were successfully prepared by electrospinning using boehmite sol containing PVP as the spinning solution. Several techniques, including Fourier transform infrared (FT-IR), thermal gravimetric analyzer (TGA) and field emission scanning electron microscopy (FE-SEM) were used to characterize their ingredients, thermal properties and morphology. The results showed that PVP concentration exhibited significant effect on the PVP/boehmite nanofibers morphology. With increasing PVP concentration, the morphology changed from beaded, beaded fiber to uniform fiber. These PVP/boehmite nanofibers can be used as good candidates for continuously preparing uniform and compact alumina nanofibers.
