Abstract

Poly(vinyl acetate) (PVAc) composite nanofibers containing different ratio of heptahydrated ferrous sulfate were directly prepared via electrospinning method. The effect of solvent and heptahydrated ferrous sulfate compositions on the resultant fiber morphology was examined. Furthermore, the mechanical properties of pure PVAc nanofibers and PVAc composite nanofibers were examined with universal testing machine. As evidenced by stress-strain curves, the yield stress and tensile strength of PVAc composite nanofibers are much higher than those of pure PVAc due to increase of intramolecular force by forming a charge transfer complex.
