Abstract
Achieving mechanical robustness, efficient ion transport, environmental tolerance, and energy conversion in a sustainable soft conductor remains challenging. Herein, a low-water-content supramolecular gel (PLPG) was fabricated via evaporation-induced co-assembly of poly(vinyl alcohol) (PVA), phytic acid (PA), and lignosulfonate (LS). Evaporation reconstructed a ternary hydrogen-bonding network. At an optimized LS content, PLPG-L0.5 exhibited 267 kPa tensile strength and 0.2676 S m-1 ionic conductivity, retaining flexibility and conductivity after 7 days at -20 °C. As a strain sensor, it showed electrical responses after 3000 s cyclic loading tests and enabled monitoring of human motion. The aromatic conjugated structure of LS allowed rapid heating above 65 °C under solar irradiation (0.1 W cm-2). Integrated with a thermoelectric generator, the system tuned the electrical output with light intensity and drove a miniature fan. This offers a strategy for lignin-based soft materials integrating wearable sensing and photothermal energy conversion.
As a major byproduct of the pulp and paper industry, lignosulfonates can be converted into photothermoelectric gels via their inherent structural advantages, offering an effective pathway for high-value utilization of agricultural and forestry wastes, source reduction of plastic pollution, and circular economy developm...

Efficient hydrogen peroxide (H2O2) photosynthesis in water is a highly desirable yet challenging route for sustainable energy and environmental applications, primarily hindered by poor charge separation and severe backward degradation. Herein, we develop a molten-salt-induced defect engineering on ultrathin carbon nitr...
Harvesting ambient renewable energy requires materials that can retain their function under coupled and often harsh environmental conditions. Flexible phase-change materials (PCMs) are promising for wearable systems because they can integrate thermal regulation, physiological sensing and energy harvesting. Here, inspir...
