壳聚糖纳米纤维膜在抗菌方面的研究进展OA

With the rapid development of biomedical and associated industries,the demand for novel antibacterial materials is increasing yearly.Chitosan,as a typical natural polymer material,has attracted lots of attention and research interest,which are originated from its wide availability,good compatibility and biodegradability,and its ability to endow fiber fabrics with biological functions such as antibacterial,antiviral and deodorizing properties.However,the practical applications of chitosan is restricted by its limited antibacterial properties and its sensitivity to acidity and alkalinity.Hence,researchers have concentrated on altering chitosan nanofiber membranes to improve the antibacterial activity of chitosan and its derivatives.The current development status and antibacterial mechanism of chitosan nanofiber membranes were elaborated in this review.Moreover,it also summarized the recent blending modification(including co-spinning with antibacterial agents and other active substances)and chemical modification(including coupling and cross-linking with antibacterial agents)techniques for membranes along with their applications in food preservation,biomedicine and coatings.Furthermore,the future development trends of chitosand is prospected,which can provide certain support for subsequent research on chitosan nanofiber membranes.
