Morphology of electrospun PVA nanofibers enhanced with graphene oxide, Poly (3,4 ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS), and multiwalled carbon nanotubes

Morphology of poly(vinyl alcohol) (PVA) nanofibers was studied while varying needle-collector distance and concentrations of graphene oxide, poly (3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS), and functionalized multiwalled carbon nanotubes. Most notably, we found that variations in...
