Physical Properties of PA6/PVA Blends Nanofibers via Electrospinning Technique

Abstract

Polyamide (PA) and polyvinyl alcohol (PVA) electrospun nanofibers for the removal of contaminated water with waste oils, were created in this study. In order to develop the nanofibers, PVA was selected as the substrate after being dissolved in formic acid with varying polymer concentration. In varying ratios of polyamide to polyvinyl alcohol, and varying electrospinning parameters of the polyvinyl alcohol and formic acid solution, the following were used: higher voltage (20 kV), pump distance (15 cm), and pump rate (1 ml/hour) were selected. Several solution parameters were measured and included viscosity, and surface tension and electrical conductivity. The results from scanning electron microscopy (SEM) and the differential scanning calorimetry (DSC) showed with increased concentrations of polyamide in the mixture, viscosity was decreases, and electrical conductivity of the solution was increased, which also resulted in a change in surface tension according to the results of the SEM. Increased electrical conductivity with decreased viscosity resulted in a decreased fiber diameter.
