SEM INVESTIGATION OF CHITOSAN NANOFIBERS PRODUCED BY NANOSPIDER TECHNOLOGY

摘要

Nanofibers from chitosan were obtained by the NANOSPIDER technology. The structure of the nanofiber layer was analyzed by the method of scanning microscopy on a JSM-5610 LV JEOL. It is found that the most reasonable concentration of chitosan (in the test interval) is 2.0 wt.%. In this case, the process is stable, and nanofibers are formed with a diameter of up to 250 nm. Based on these results, the optimum technological parameters of the electrospinning used for manufacturing high-quality uniform nanofiber coating have been determined. However, the use of different types of chitosan, as well as substrates of differing nature and structure, may require adjustment of these parameters.
