Summary: To achieve biocompatibility, mechanical strength, and sustained antibacterial properties in medical materials, it is proposed to incorporate antibacterial material components into a biomass matrix. In this study, zinc oxide (ZnO) was synthesized in-situ in a bacterial cellulose (BC) dispersion and combined with sodium alginate (Alg) to form a layered composite film. The BC/ZnO/CAlg composite film exhibited excellent mechanical strength and antibacterial properties, attributed to the synergistic effect of the Zn2+ cross-linked Alg and the BC/ZnO composite film. Furthermore, the sustained-release migration of Zn2+ from the inner layer to the outer layer was observed, enabling long-term antibacterial performance against Staphylococcus aureus and Escherichia coli.

Summary: A novel composite film for food packaging was prepared using hydroxyethyl cellulose (HEC), carboxymethyl chitosan (CMCS), and zinc oxide nanoparticles by solution casting method. Spectroscopy, crystallography, and morphology observation confirmed the successful incorporation of nanoparticles. The addition of CMCS and ZnO improved the solvent resistance (reduced water solubility by 94.3%) and UV shielding ability (increased UV shielding capacity by 45.73%) of the film, enhancing its potential applications in water-rich foods. The composite film demonstrated efficient inhibition (>99.99% inhibition rate) of pathogenic bacteria Listeria monocytogenes and Pseudomonas aeruginosa, with the synergistic effect of CMCS and ZnO. Furthermore, CMCS and ZnO significantly enhanced the elasticity (494.34% improvement) and maximum load capacity (142.24% improvement) of the composite film.

Summary: In this study, composite films were produced by blending chitosan, rice protein hydrolysates, and cellulose nanocrystals (CNC) at different concentrations. The presence of CNC led to the formation of stronger and more uniform films with improved mechanical, thermal, and barrier properties. The CNC-film matrix interactions reduced water affinity, resulting in reduced moisture content, water solubility, and water vapor transmission. The addition of CNC also increased the thermal stability of the films. Moreover, the composite films exhibited strong antibacterial activity against E. coli and S. aureus, especially when combined with ZnO nanoparticles.

Summary: A strategy of using multi-modulus components is proposed to fabricate strong and tough cellulose-graphene oxide (GO) composite hydrogels. The critical parameters for achieving high strength and high toughness in the composite hydrogels are the GO nanosheet content, molar ratio of the GO crosslinker to anhydroglucose units of cellulose, and ethanol concentration. The composite hydrogels showed excellent photothermal antibacterial properties against Escherichia coli and Staphylococcus aureus under near infrared irradiation.

Summary: This study utilized carboxylic acid-based deep eutectic solvents for pretreating cellulose, resulting in the production of cellulose nanofibers with widths less than 100 nm through simultaneous esterification modifications. Esterification modifications prevented over-hydrolysis and dissolution of cellulose while maintaining the cellulose I crystal structure. The esterified cellulose nanofibers showed improved dispersibility and interfacial compatibility with polylactic acid, leading to mechanical enhancement of CNF/PLA composites.

Summary: Paper-based catalytic composite films were prepared by synthesizing nanolignin on a filter paper and reducing Pd ions to Pd nanoparticles. Two different routes were used to prepare alkaline lignin NPs, with LAL NPs having a broader size range compared to RAL NPs. The AL NPs on FP acted as a reducing agent for the reduction of Pd2+ and were efficient in catalyzing the reduction of Cr6+ to less toxic Cr3+. The presence of FP influenced the dispersity and uniformity of the NPs, affecting the content of Pd NPs and the efficiency of Cr6+ reduction.

Summary: In this study, esterified lignocellulose nanofibers (LCNFs) with high yield were prepared from lignocelluloses (LCs) with different lignin contents by swelling with a lactic acid/choline chloride deep eutectic solvent (LA/ChCl DES) followed by mechanical colloid milling. The lignin in the esterified LCNFs acted as an interface adhesive, increasing the compatibility between LCNFs and PLA and enhancing the mechanical properties of the composites. The optimized flexural properties of the composites reached a maximum value of 204.5 MPa when 20% LCNF (containing 10.92% lignin) was added, showing great potential as a replacement for non-degradable plastics.
