Summary: This study presents the fabrication of eco-friendly, UV-shielding transparent wood (TW) using waste lignin as a resource. Three different pretreatment methods were explored, and the average size of the lignin nanoparticles (LNs) was around 100 nm. By incorporating just 1% of LN, the TW composites effectively blocked all UV-C, UV-B, and UV-A radiation while maintaining adequate visible light transmittance. The NaOH delignification TW showed the highest transmittance, tensile strength, UV-shielding functionality, and comparable thermal stability.

Summary: Lignin, a versatile bioaromatic polymer, was modified by selective phenolation to enhance its phenolic hydroxyl content and achieve a more uniform structure. The resulting lignin particles were used to prepare Pickering emulsions for AVM encapsulation, leading to improved stability, anti-UV and anti-oxidant capacities. The encapsulation efficiency of AVM in the lignin-based Pickering emulsion was significantly increased, and the release of AVM could be controlled according to application demands.

Summary: In the synthesis of materials using biomass-derived natural polymers, a UV-shielding film made from biodegradable lignocellulosic waste was successfully created. This was achieved by processing corncob residue with varying lignin content through alkaline peroxide treatment and then dissolving cellulose-rich solid residues in ZnCl2/CaCl2 solvent and reconstituting them with ethanol. The resulting lignocellulose films exhibited tunable mechanical and UV-shielding properties, with the film containing 6.5% lignin showing the best performance. This study presents a novel process for utilizing corncob residue and producing functional biomaterials.
