Polyvinyl alcohol (PVA) is widely used in food packaging, drug release materials, and crop growth applications but suffers from accelerated aging due to sunlight exposure. Lignin can be used as a filler in polymer membranes to prevent degradation and to block the ultraviolet light that is harmful to crops and plants. However, traditional blending methods result in composite membranes with inferior mechanical properties compared to pure PVA ***, PVA-g-LGC is synthesized with PVA and alkali lignin-grafted 3-acryloyl-7-diethylamino coumarin (LGC). LGC serves as an UV-responsive pore-forming agent, facilitating the radical copolymerization of PVA with LGC. PVA-g-LGC exhibits an ultraviolet transmission value approaching zero within the 200 to 400 nm range. Subsequently, it was discovered that the transmittance of visible light for the PVA-g-LGC membrane surpasses that of a PVA/LGC blending membrane by a significant margin of 155.2%. Furthermore, the CO2 permeable ability of the PVA-g-LGC membrane is astonishingly enhanced by a remarkable factor of 66.44 compared to the PVA membrane. Notably, after 9 min illumination under 1 sunlight, the temperature of the PVA-g-LGC membrane surface escalates to 34.6 °C, surpassing the temperature of the PVA/LGC blending membrane by 1.8 °*** work presents a facile one-step strategy to fabricate a porous PVA-g-LGC composite membrane with UV protection, enhanced CO2 permeability, and photothermal insulation properties. Derived from alkali lignin, this environmentally friendly coating can prevent UV radiation damage to people, animals,and plants and protect indoor and outdoor decorations from discoloration,making it a promising material for sustainable applications. © 2024, The Authors.

Achieving High-Efficiency Fractionation and Conversion of Lignocellulosic biomass with Hydrated Deep Eutectic Solvents

Lignocellulosic biomass as the most abundant and renewable resource has received globally tremendous attention, whose efficient fractionation and conversion are essential and urgent. Herein, an one-pot pretreatment with hydrated deep eutectic solvent (HDES), composed by choline chloride (ChCl), acetic acid (AA) and water molecules, was proposed to fractionate lignocellulosic biomass. The pre-extraction yield of lignin and hemicellulose by HDES reached up to 95.41% and 91.26%, respectively;the glucose and xylose yield of cellulose-rich residues were up to 92.67% and 98.29%, respectively. In addition, HDES alleviated excessive destruction and condensation of lignin to a certain degree, and increased the active groups amount (e.g., phenolic –OH), obtaining a light-color lignin with unique properties, such as high colloidal stability and thermal stability, low particle size, and reduced molecule weight with narrow distribution, as well as distinguished antioxidant and anti-UV capacity. It is believed that the proposed process is an effective approach to realize highly efficient fractionation and conversion of lignocellulosic biomass. © 2025, The Authors. All rights reserved.
