Abstract

Electrospinning is a method for creating nanofibers by utilizing an electric field produced by high voltage. Electrospinning process is influenced by several factors including the concentration of the solution, conductivity, viscosity, volatility, surface tension, electric field strength between the needle and the collector, feed/flow rate and environmental conditions such as temperature, humidity and air composition. The electrospinning parameters that most influence the size of the fiber are concentration of the solution and the distance between nozzle and collector. In the process of electrospinning, PVA solutions that are handled by high DC voltage get an electrostatic force and electric field. The solution will elongate to form a Taylor cone, then a jet of polymer will undergo thinning and evaporation to form fibers in the collector. The results of morphological analysis using Scanning Electron Microscopy (SEM) showed that the smallest nanofiber was obtained at a solution concentration of 5%, DC high voltage of 10 kV, and the distance of the nozzle to collector was 15 cm.
