Abstract

PVA nanofibers have been successfully prepared via an electrospinning process by optimizing the electrospinning operational parameters including applied voltage, polymer concentration, feed rate, and working distance. Inexpensive NaCl and Fe(NO₃)₃ are found to reduce the fiber size drastically (minimum of 157 and 169 nm, respectively) even at a lowloading. The thermal stability is investigated by both thermogravimetric analysis and differential scanning calorimetry. Fourier transform infrared spectroscopy is utilized to characterize the functionality of the fibers and to investigate the interaction between PVA and inorganic additions. Glass transition and melting temperatures of the PVA fibers have slight change with the increase of the salt loading. Optimum operational parameters are obtained for fabricating high quality poly(vinyl alcohol) electrospun fibers. Sodium chloride and iron(III) nitrate are discovered having significant effects on the quality of nanofibers. ©
