Abstract

This work is dedicated to study the process of producing nanofibers from blended polymer solutions of chitosan and polyvinyl alcohol, and the status of the issue was reviewed based on a review of literature data. The concentration of chitosan / PVA solutions varied from 3 to 6% in the studies. The morphology of the fibers was examined by Scanning Electron Microscopy (SEM).
