Bio-based packaging materials and efficient drug delivery systems have garnered attention in recent years. Among the soluble cellulose derivatives, carboxymethyl cellulose (CMC) stands out as a promising candidate due to its biocompatibility, biodegradability, and wide resources. However, CMC-based films have limited mechanical properties, which hinders their widespread application.

However, the insolubility in water restricts its wide application. In order to expand the application of chitosan in the delivery of oil-soluble drugs and improve the efficacy of oil-soluble drugs, -Glycidyltrimethyl ammonium chloride-modified chitosan (GTA-m-CS) and ,-Dimethyl--dodecyl--(1,2-epoxy propyl) ammonium chloride (DDEAC), a kind of reactive surfactant, were synthesized and characterized by FTIR, NMR and XRD methods.

- A zwitterionic chitosan derivative, HTCMCh, was synthesized and added to carboxymethyl cellulose (CMC) films to enhance film strength and provide antibacterial properties.
- The study evaluated how factors like the degree of substitution and mass content of HTCMCh affected mechanical properties, thermal stability, microstructure, and antibacterial effectiveness of the CMC-based films.
- Results showed significant improvements in tensile strength, Young's modulus, and elongation at break of the films, while also demonstrating effective antibacterial activity against E. coli and S. aureus, making these films suitable for food packaging applications.
