In this work, electrospinning processing parameters of PVDF nanofibers are changed to analyze theirinfluence on fiber morphology and crystal phases. Fourier Transform Infrared (FTIR) spectroscopy was performedto study skeletal changes and crystallinity of the PVDF chains in the electrospun fibers. Fiber morphologies wereinvestigated using scanning electron microscopy (SEM). Fiber diameters increased as flow rate enhanced from 0.5to 1 ml/h. For fibers spun with pure DMF, the fraction of β phase increased slightly when the applied voltageincreased from 13 to 21 KV.
