Abstract

Electrospinning is a known process to produce nanofibers through electrostatic forces. In a typical process, an electrical potential is applied between droplets of polymer solution or melt, held through a syringe needle and a grounded target. In general electrospinning fibers are collected on the grounded target as a random oriented web of nanofiber. Various research projects are attempted to obtain aligned electrospun fibers. This modified electrospinning method can be developed and used in a variety of nanofiber-based applications such as making of nanofibrous scaffolds for tissue engineering. In this study, an effective method has been developed to fabricate ALIGNED NANOFIBERS by manipulation of electrospinning system using two nozzles with opposite charges. Moreover, the effect of some parameters including take-up velocity, applied voltage and polymer solution concentration on alignment of produced nanofibers is investigated. The comparison of fibers alignment was carried out by programming and image processing in MATLAB. It is shown that take-up velocity and polymer solution concentration have significant effect on increasing the fibers alignment. Also, the alignment is increased with applied voltage at first and then, it is decreased. The analytical results and optical microscopic images are clear evidence of showing the maximum alignment of nanofibers obtained at 15% polymer solution concentration with take-up velocity of 600 rpm and 11 kV voltage.
