The morphology and scaling law model of polyvinylidene fluoride/carbon fiber using electrospinning technique

Electrospinning is a simple process used for polymer fibers that have diameters ranging from micro to nanometers. The purpose of this study was to investigate the morphology and scaling law model of Polyvinylidene Fluoride/Carbon (PVDF/Carbon) fiber math. Fiber is made by variations in concentration 15% w/w (FPC1), 18% w/w (FPC2), 21% w/w (FPC3) and 24% w/w (FPC4) by adding of 2% (w / w) carbon in each solution. The electrospinning process parameters used are 10 kV voltage, needle tip distance and collector 12 cm, and flowrate 0.1 ml / hour. The results showed that the morphology of FPC1-FPC2 fibers was in the form of bead and the morphology of FPC3-FPC4 are structure free bead. The avarege diameters of FPC1, FPC2, FPC3 and FPC4 are 910 nm, 1123 nm, 1349 nm and 1506 nm, respectively. The scaling law models result R Square (R²) of the experiment was 0.9992, indicating a very linear model relationship between theory and experiment. Polyvinylidene Fluoride/Carbon (PVDF/Carbon) fiber composite will be used as water filtration. (paper)
