fabrication of novel polyethylene glycol/polyvinylidene fluoride nanofibers/spheres composite via electrospinning

Polyethylene glycol (peg)/polyvinylidene fluoride (pvdf) nanofibers/ nanospheres composite were fabricated using coaxial electrospinning# in the composite nanofibers, peg and pvdf blending solutions were coaxially electrospun (e-spun) through a spinneret and using a high-voltage power supply# the electrospinnability of the blending solutions was also investigated by varying the blending ratio of the peg and pvdf, and it enhanced with the increase of peg content# the novel structure of the e-spun composite nanofiber was confirmed using scanning electron microscopy (sem)# sem results showed that the fibers size was varied in the range of 70 nm-250 nm with smooth surface and coreeshell structure#
