ELECTROSPUN CHITOSAN- POLY ETHYLENE OXIDE BLEND NANOFIBERS FOR MEDICINE APPLICATIONS

In recent years, electrospinning as an easy and effective method in producing nanofibers with diameters ranging from microns down to a few nanometers has been developed.Chitosan (CS) is a multifunctional biodegradable polycationic biopolymer that has been used in a variety of differentindustrial applications. However, the electrospinning of the CS due to its low solubility, low stability, and low mechanical properties does not produce the fibrous structure. Therefore,the polymers such as poly ethylene oxide (PEO), poly vinyl alcohol (PVA) and poly caprolactone (PCL) were blended toCS to improve its electrospinning ability. In this work electrospun CS/PEO blend nanofibers was investigated with CS solution from 1-7 wt% in 0.5 M acetic acid.
