Electrospinnability of Poly(vinyl alcohol) and its Biopolymer Blending Solutions

The effects of PVA concentration, spin voltage and solidification distance on electrospinning were studied. It was found that PVA concentrations in the ranges of 5 %~ 8 %, spin voltage between 6.6~ 15 kV, solidification distance within 5 ~ 15 cm were suitable for electrospinning. Three kinds of PVA blend ing solutions, namely PVA/SA with 8 % / 0.5 %~1 %, PVA/SS with 8 % /2 %~4 % and PVA/CS with 8 % /2 %~3.5 % were suitable for the electrospinning and could produce nanofibers with good shape.
