Summary: By using chitosan and sodium carboxymethyl cellulose as raw materials, a polyelectrolyte complex (PEC) was successfully prepared through strong electrostatic interaction. The reactive contact area between the two bio-based polyelectrolytes was enlarged by preparing a crosslinked vacuolar structure without the use of a cross-linker. The yield and bibulous rate of PEC were significantly affected by the preparation conditions, yielding a PEC with 71.2% yield when pH, CMC-Na-to-CTS ratio, stirring speed, and reaction temperature were optimized.

Summary: Water-soluble polyvinyl alcohol/carboxymethyl chitosan (PVA/CMCS) blend fiber films were successfully prepared with improved shear viscosity and spinnability. The addition of CMCS increased crystallinity and maintained uniform distribution in the PVA matrix. Biocompatibility of the PVA/CMCS blend fiber films was confirmed by in vitro cell study. The films also exhibited promising antibacterial properties.

Summary: Nisin-loaded carboxymethyl chitosan nanogels (CN NGs) were prepared through a combination method of electrostatic self-assembly and chemical cross-linking, demonstrating good dispersion and spherical structure. The main driving force in the formation of CN NGs was found to be the electrostatic interactions and hydrogen bonding between nisin and CMCS. Additionally, the CN NGs exhibited controlled release behavior of nisin and excellent antimicrobial activity, indicating their potential as a bio-preservative in the food industry.

Summary: In this study, a novel edible biomaterial composed of monomethoxyl polyethylene glycol-modified O-carboxymethyl chitosan (MPEG-O-CMC) was developed for fresh-keeping food packaging materials. The introduction of polyethylene glycol (PEG) improved the film's hydrophilicity, thermal stability, flexibility, and tensile features. The films showed good tensile properties, acceptable water vapor transmission rates (WVTR), and potential bacteriostatic activity against Escherichia coli.

Summary: pH-sensitive and amphiphilic chitosan derivatives were synthesized and studied for their rheological properties, showing that high degree of substitution and pH near the isoelectric points corresponded to low viscosity and viscoelasticity. Strong networks formed at high concentrations, and the role of Ca2+ varied depending on concentration levels. Molecular dynamics simulations were also used to examine intermolecular hydrogen bonds.
