Polyvinylpyrollidone/Cellulose Acetate (PVA/CA) Fiber Size Prediction Using Scaling Law Model

Abstract

The purpose of this research was to compare the diameter of the fiber produced using the electrospining method and scaling law model. The electrospinning process is a simple technique in producing nanofibers from the incorporation of various polymers. The polymer material used is Poly (vinylpyrrolidone) (PVP) with Cellulose acetate (CA) solvent. Cellulose acetate (CA) solvents using different concentrations were 6% (PC 1), 10% (PC 2) and 17% (PC 3). The process parameters used electrospinning voltage is 10 kV, the needle tip to collector distance is 13 cm and flowrate used is 3.2 μL/hour. The product of nanofibers was morphologically characterized using a digital microscope and the fiber diameter size was predicted using a scaling law model. The scaling law model predicts electrical conductivity in PC 1, PC 2, PC 3 samples are 0.004298 S/m, 0.001289 S/m, and 0.000374 S/m respectively. The results of the logarithmic comparison of Q/K to the diameter of the nanofiber produce a linear graph pattern with a decrease in the value of K resulting in the diameter of the nanofiber-based on the results of experiments that have been carried out.
