The Influence of PVOH Concentration on the Structural Morphology and Dimension of Electrospun Nanofibers

: The parameters applied in electrospinning process were the main factors to produce ultrafine nanofibers for different target applications. In this study, the effect of polyvinyl alcohol (PVOH) concentration, from 12% to 16% (wt) in distilled water, on the morphology and dimension of nanofibers was investigated. Scanning electron microscopy (SEM) was used to analyze the morphology of PVOH electrospun nanofibers and Image J analysis was used to calculate the dimension of fibers. From the results, 12% and 13% of PVOH concentration produced bead shaped fibers. Meanwhile ultrafine nanofibers were produced from PVOH concentration of 14%, 15%, and 16% (wt). The diameter of ultrafine fibers increased with the increase in PVOH concentration.
