Improving Chitosan/TFA Electrospinning Process using a Physical Crosslinking Agent

The main goal of this paper is to study the effect of increasing chitosan polymer chain interactions in order to improve its electrospinning conditions, by adding phosphotungestic acid (PWA) as a physical crosslink agent. Analyzing the SEM pictures indicates that free beaded nanofibers are obtained at lower polymer concentration with the present of phosphotungestic acid in chitosan/TFA solutions, which is believed to be related to the enhancement of hydrogen bonding between polymer chains and the crosslinking agent
