Given the green developments in interfacial solar steam generation (ISSG), a biobased evaporator with excellent photothermal conversion efficiency is urgently needed to address freshwater shortage. However, it still challenging that evaporators like wood and bamboo are underutilized due capillary actions different channel directions. Herein, we investigated structural properties of veneer for contrast analysis between transverse sections (BTR) tangential (BTA). The one-step torrefaction method was used improve optical absorption lignin 200–2500 nm band. Owing perpendicular design, BTR conducting straight energy loss bulk water restricts performance. BTA evaporator's parallel design micronano unit presents better management (surface temperature could reach 57.1 °C under 1 kW/m2 illumination), leading efficient evaporation performance (1.425 kg/m2 h). These findings contribute our cognition solar-driven transport suggest ISSG develop produce from seawater or sewage.

In this study, we introduce an innovative one-step, solvent-free approach for preparing lignin-containing polyurethane elastomers (LPUes) with nanomicro phase-separated structure and dynamic dual-cross-linking networks comprising both phenol-carbamate bonds (PCBs) hydrogen bonds. This distinctive structural design imparted exceptional mechanical properties to the LPUes. The sample containing 22.9 wt % phenolized lignin exhibited tensile strength of 44.6 MPa, elongation at break 714.6%, toughness 148.0 MJ/m3. abundance PCBs also conferred remarkable reprocessing capabilities, these LPUes retaining over 98% 94.4% after two hot-pressing cycles. Moreover, incorporation endowed photothermal properties, facilitating efficient light-controlled self-healing shape-memory functionalities. work offers pathway harmonize thermal adaptability in development sustainable high-performance LPUes, thereby opening their avenues diverse potential applications.

Degradable paper-based packaging materials are promising alternatives to plastic packaging. However, the inherent limitations of paper, such as poor water and oil resistance, restrict its broader applications. It is essential develop green degradable coatings compensate for shortcomings paper materials. In this study, we prepared a tough, hydrophobic, stain-resistant, lignin-based waterborne polyurethane (LWPU) coating. LWPU emulsions with good stability were synthesized using low-molecular-weight lignin (LMWL) polycaprolactone diol (PCL) raw poly(dimethylsiloxane) (PDMS) modifier. films exhibited excellent mechanical properties, optimal tensile strength 40.3 MPa elongation at break 1148%, hydrophobicity, antiaging UV shielding. The properties coated papers significantly affected by emulsion permeation type substrate. dense coating enhanced barrier performance against water, oil, gas. Incorporating PDMS segments into further improved hydrophobicity stain resistance allowing easy removal common stains. Moreover, can be completely removed from solvent-dissolving chemical degradation methods, which advantageous recycling. This work provides reference industrial application coatings.
