Polyvinylidene difluoride (PVDF) fibers were prepared by electrospinning from dimethyl formamide (DMF),acetone solutions. The effects of the electrospinning processing conditions on the formation of the α and β phases of PVDF were studied using infrared spectroscopy(FT-IR) and X-Ray Diffractometer(DSC). Through the control of electrospinning parameters such as the applied voltage, feeding rate, and tip-tocollector distance, concentration, the frcation of β phase in electrospun membrane can be greater or smaller. |
