Lignin is a natural and nontoxic biomass material. It not only has antibacterial activity but also exhibits antioxidation UV shielding properties, which great potential application in food packaging, the medical fields. However, with complex structure, efficiency of lignin quite low. therefore necessary to improve performance broaden its applications. In this study, LZM hybrid nanoparticles ZnO, long-chain quaternary ammonium salt structures were prepared by simple self-assembly method. Antibacterial compatibility PBAT nanolignin was achieved one step via surface modification. The rates against E. coli S. aureus reached up 100%. Subsequently, filled into solvent casting prepare PBAT/LZM composite films, showed good between PBAT. exhibit reinforcing toughening effects on composites. Especially, tensile strength PBAT-3%LZM film increased from 33.2 37.6 MPa. Meanwhile, bacterial adhesion concentration decreases 14 × 105 CFU/mL 6 104 CFU/mL, while no longer adheres aureus. Furthermore, PBAT-2%LZM at λ = 320 nm more than 99.0%. These interesting results will support films be applied packaging devices. Hence, simultaneously LNPs'

Porous Lignin Nanospheres as Microscopic Air Purifiers for Antioxidant‐Configurable Cigarette Filters

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: March 9, 2025

Abstract Trees, consisting of leaves, trunks, etc., efficiently eliminate gaseous pollutants and serve as an indispensable air purification system for Earth. In this study, lignin from trunks phytol leaves are co‐assembled into macroporous nanospheres with high efficiency scavenging reactive oxygen species (ROS) harmful gases, which integrated cigarette filters lung protection. The alkyl chains disrupt the π–π stacking in lignin, forming pore throats that expand 0 to 120 nm content increases. Consequently, higher levels anchored phytol, greater antioxidant capacity co‐assemblies. subsequently loaded filters, each gram porous nano‐lignin capable treating ≈100 standard cigarettes. ROS can reach up 97%, effectively removing gases like carbon monoxide formaldehyde, outperforming existing filters. a mouse model, containing these microscopic purifiers significantly suppressed inflammation provided notable tissue This study presents robust non‐covalent method is both straightforward efficient, enabling rapid application plant extracts highly effective sustainable filter materials.

Fabrication of Lignin/Pbat Biodegradable Plastics Films via Reactive Extrusion and Their Thermal, Mechanical and Water Absorption Properties

Published: Nov. 6, 2023

Biodegradable and renewable plastic films have been regarded as promising alternative green materials to achieve the substitution polythene (PE)films reduce pollution. Poly (butylene adipate-co-terephthalate) (PBAT) is a kind of biodegradable polyester, which widely used in production mulching films. However, high cost PBAT limited it applications. Thus, lignin, one most abundant biomass resources was incorporated into matrix present work. A series Lignin/PBAT plastics with different weight ratios (0.00 %-5.00 %) were successfully fabricated using twin screw roll extruders. The chemical compositions, morphologies, thermal stabilities, mechanical properties, barrier properties samples characterized by XRD, FTIR, TG/DSC, testing machine, WVTR, respectively. Results show that corporation lignin could lead improved even after Xenon lamp aging process, especially when ratio 1.00 % This work provides very approach for fabrication low cost, enhanced as-prepared may potential applications agricultural or food packaging materials.
