"Development of Handmade Electrospinning Technique for Production of Nanofibers and Study Some of Its Applications"

Abstract

Electrospinning technique became powerful tool to production of polymeric nanofiber at the end of twentieth century. Also, nanomaterials have different and attractive properties from its properties in bulk state. In our study, the steps of optimization of electrospinning technique were presented. Also, the different parameters that used to produce nanofiber from natural and synthetic polymers were presented in detail. Sodium alginate is a natural polysaccharide polymer, and has various properties such as: biocompatible, biodegradable, non-toxic and water soluble. In our work, some experiments were performed to produce nanofiber from sodium alginate solution but with negative results. So that, synthetic polymer such as polyvinyl alcohol was used to enhance the electrospinnability of sodium alginate. Nanofiber from pure PVA was prepared successfully at optimal process condition; distance, rotational speed, flow rate and voltage equal to 9 cm, 5500 rpm, 0.03 mL/Min, 20 KV respectively. Based on the previous step Nanofiber sheet from Na Alg and PVA was successfully at optimal process condition; distance, rotational speed, flow rate and voltage equal to 9 cm, 2000 rpm, 0.009 mL/Min, 20 KV respectively. After that, to improve the mechanical properties of the produced nanofiber, plasticizer such as glycerin was used. Then the plasticized
