Polyvinylidene Fluoride (PVDF) fibers were electrospun from PVDF solution with varied solvent mixing ratios of Dimethylformamide (DMF) and acetone in this work. The goal of this study is to see how the mixing ratio of DMF and acetone as solvent affects the fiber size, crystal structure, and electrical conductivity of PVDF fiber. In weight, the solvent mixing ratios are 100 DMF:0 acetone, 70 DMF:30 acetone, 50 DMF:50 acetone, 30 DMF:70 acetone, and 0 DMF:100 acetone. To be employed in this study, the PVDF solution was fixed at a concentration of 15%. The electrospinning machine parameters were likewise set to 20 kV, 10 cm tip-to-collector distance (TCD), and 1 mL/h flow rate. After the electrospinning process is completed, the sample will be kept for a short period of time in room temperature to allow the fiber to dry before being taken for characterization stages. Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), and Four-Point Probe (FPP) were used to examine the fibers. The fiber size of electrospun PVDF fibers is shown by SEM; the crystal structure of the electrospun PVDF fiber is shown by XRD; and the electrical resistivity of the electrospun PVDF fiber is shown by FPP. According to the results of the experiment, one of the five samples is in powder form, while the other is in fiber form. Two of the four fibers produced contain beads, as determined by SEM. For XRD and FPP characterization, it was discovered that a sample with a high peak intensity of β phase produces the maximum electrical conductivity.
