Design of morphology and physical properties of chitosan-gelatin nanofibers by coaxial electrospinning

In this work, chitosan and gelatin solutions were subjected to coaxial electrospinning. Using statistical analysis of scanning electron microscopy data, the formation of core-shell nanofibers with an average diameter from 79 to 90 nm was shown. The study of the stability of electrospinning showed the stabilization of the process with an increase in the content of acetic acid in the gelatin solution. According to the analysis of the mechanical properties of nanofiber materials, a twofold increase in the Young's modulus was revealed with an increase in the content of acetic acid from 50 to 90 vol.%.
