Chitosan-based nanofibers are widely used in the antibacterial field. Chitosan has good biodegradability, non-toxicity, antibacterial properties, high safety, and environmental friendliness. The nanofiber structure can achieve better surface interactions and enhance the inhibition of bacteria. However, due to the rigidity and ionic structure of chitosan, the production of chitosan-based nanofibers is challenging. By mixing chitosan with different polymers and antibacterial agents, the spinnability of the nanofibers can be optimized, and their antibacterial performance can be improved. This article first briefly describes the antibacterial mechanism of chitosan. Then, it introduces the influence of chitosan from different sources on antibacterial activity, the intrinsic factors affecting the antibacterial property of chitosan, the influence of structural modification of chitosan on antibacterial performance, and the influence of chitosan crosslinking agents on the mechanical properties and antibacterial performance of nanofibers. Subsequently, it elaborates on the progress of research on the antibacterial properties of chitosan-based nanofibers from two dimensions: chitosan-based binary antibacterial and chitosan-based ternary antibacterial. Finally, it analyzes the main challenges faced by the commercialization of electrospun chitosan-based nanofibers and looks forward to the development direction of chitosan-based antibacterial nanofibers.
