Abstract

Abstract: Electrospinning is a versatile method to produce nanofibers. Electrospun nanofibers have been extensively used in many industrial applications such as wound dressing, sensor, protective clothing, and filters. However, producing nanofibers efficiently through a single-needle electrospinning technique is still challenging. In this study, a system of needleless electrospinning with a wire spinneret was utilized to produce Polyvinylpyrrolidone (PVP) nanofibers. Process parameters comprised concentration of solution, applied voltage, flow rate of solution, collection distance, and diameter of the wire spinneret were altered to examine morphology, diameter, and productivity of the produced fibers. SEM images showed that morphology of the produced fibers was affected by concentration of PVP solution. Moreover, diameter of the produced fibers could be varied by controlling the process parameters. Our needleless electrospinning system has proved to be more productive in producing fibers than the single-needle electrospinning system.
