TLDR
Electrospinning of pure chitosan was hindered by its limited solubility in aqueous acids and high degree of inter- and intrachain hydrogen bonding, and surface properties of fiber mats were determined by measuring the binding efficiency of toxic heavy metal ions like chromium, and they were found to be related with fiber composition and structure.About:

Bending instability of electrically charged liquid jets of polymer solutions in electrospinning
TL;DR: In this paper, the authors analyzed and explained the reasons for the instability of a viscous jet of polymer solution at a pendent droplet, showing that the longitudinal stress caused by the external electric field acting on the charge carried by the jet stabilized the straight jet for some distance.
