The service life of bitumen pavement is impacted by ultraviolet (UV) light and some other conditions, which affected the physical properties and rheological behaviors of bitumen obviously. Lignosulfonate grafted layered double hydroxides modified bitumen (LS-g-LMB) was prepared, and the evaluation of UV aging resistance was investigated through Fourier Transform Infrared Spectroscopy (FTIR), aging indexes, temperature sensitivity, dynamic shear rheometer (DSR) and rheological dynamic model analyzer. The results revealed that lignosulfonate grafted layered double hydroxides (LS-g-LDHs) could alleviate bituminous oxidation reaction, variations of aging indexes and temperature susceptibility in the period of UV exposure observably. After aging, LS-g-LMB showed better low (G', G“ and tanδ) and high temperature (G*, δ and G*/sinδ) performance than pristine bitumen (PB) and layered double hydroxides modified bitumen (LMB). Meanwhile, the instantaneous elasticity, delay elasticity and viscous deformation of bitumen could be inhibited by LS-g-LDHs based on the rheological model analyses. Therefore, the introduction of LS-g-LDHs could promote the UV aging resistance of bitumen significantly according to the changes of bituminous physical properties and rheological behaviors before and after UV aging.

Loose nanofiltration (LNF) membrane, which combines high permeate flux with excellent separation selectivity, is an ideal technical approach for efficient separation of dyes and inorganic salts. Here, sodium lignosulfonate (SL) as the aqueous phase additive, a novel polyamide-based LNF membrane with a thin polyamide separation layer was fabricated by delaying the interfacial polymerization (IP) reaction of piperazine. The resulting membrane exhibits excellent pure water permeance (82.77 LMH bar −1 ), impressive dye rejection of >99 % and low rejection for inorganic salts (Na₂SO₄, MgSO₄, MgCl₂, and NaCl, all below 10 %), demonstrating extremely high dye/salt selectivity (Congo Red/Na₂SO₄: 258.5). Additionally, the membrane maintained a CR rejection exceeding 99 % during continuous 40 h treatment of CR mixed salt solutions. As-prepared membrane exhibits excellent antifouling performance, with a flux recovery rate of up to 96.7 %, which is considerably higher than that of commercial NF270 membranes. With the help of the introduction of SL, a SL-decorated LNF with high hydrophilicity and surface negative charge promises great application potential in the field of textile wastewater treatment.

The design of efficient adsorption sites within triboelectric materials is crucial for improving the atmospheric response sensitivity and operational performance of triboelectric nanogenerators (TENGs). In this work, zeolitic imidazolate framework-67 (ZIF-67) was synthesized using sodium lignosulfonate (SLS) as a polymeric soft template (ZIF-67@SLS) and subsequently incorporated as a nanofiller with abundant adsorption sites into sodium carboxymethyl cellulose (CMC) and poly(vinyl alcohol) (PVA) matrices. The resulting flexible TENG exhibits a rapid and sensitive response to ammonia. The ZIF-67@SLS features a high specific surface area and dense active sites, which enhance ammonia molecule adsorption. The lone-pair electrons of ammonia neutralize surface charges on the TENG, altering the surface electron density and leading to a reduced output voltage. A clear concentration-dependent voltage drop is observed as the ammonia levels increase. Due to the high specific surface area and high triboelectric output performance, we used CMC/PVA/ZIF-67@0.1SLS (CPZS0.1) composite film for ammonia sensing performance evaluation. Compared to pristine ZIF-67, the CPZS0.1-based TENG shows a 41.67% reduction in response time (42 s vs 72 s) and a 58.81% increase in sensitivity (0.539 V/ppm vs 0.222 V/ppm) within the 0–180 ppm range. The optimized system enables accurate ammonia detection and effective monitoring of meat freshness in packaging applications. This study offers a promising strategy for constructing cellulose-based triboelectric composites with tailored gas-responsive behavior, advancing the development of smart sensing materials for environmental and food safety monitoring.

A sulfonate-phosphate lignosulfonate was designed for force-regulated solid–solid separation. • PSLS suppressed pyrite-serpentine hetero-aggregation through selective MgOH anchoring. • Pyrite recovery reached 85.30%, 12.88 percentage points higher than that with SLS. • P-O-Mg bonding and sulfonate electronegativity enabled selective serpentine modification. • PSLS converted pyrite-serpentine attraction into nanoscale repulsive stabilization. Hetero-aggregation between dissimilar particles limits selective separation in complex aqueous systems, as exemplified by attractive serpentine-pyrite interactions. However, conventional depressants often suffer from limited selectivity, high reagent consumption, and environmental concerns. Herein, phosphorylated sodium lignosulfonate (PSLS) was designed as a water-soluble sulfonate-phosphate interfacial regulator to suppress serpentine-sulfide hetero-aggregation. By integrating serpentine-affinitive phosphate groups with the highly electronegative sulfonate structure of sodium lignosulfonate (SLS), PSLS enables selective anchoring on serpentine and enhanced electrostatic repulsion between serpentine and pyrite. Compared with SLS, PSLS increased pyrite recovery in the mixed-mineral system to 85.30%, corresponding to an improvement of 12.88%. The surface coverage of PSLS on serpentine reached 93.72%, markedly higher than that of SLS (63.80%). Atomic force microscopy (AFM) colloidal probe measurements combined with Derjaguin-Landau-Verwey-Overbeek (DLVO) analysis further showed that the adhesion force between pyrite and the serpentine MgOH plane decreased from 6.99 mN m −1 to 2.02 mN m −1 after SLS treatment and further to 0.22 mN m −1 after PSLS treatment. These results demonstrate that PSLS suppresses pyrite-serpentine hetero-aggregation by simultaneously strengthening serpentine-specific adsorption and regulating nanoscale interparticle forces. This work provides a practical strategy for designing lignin-derived regulators for efficient solid–solid separation in complex aqueous particle systems.

The trade-off between convective mass transport and binding capacity remains a critical challenge in designing stationary phases for high-throughput biopharmaceutical purification. Herein, we report a facile and scalable fabrication strategy to construct hierarchically porous sodium lignosulfonate/polyvinyl alcohol composite aerogel fibers (LS/PVA-AFs) by integrating centrifugal wet-spinning with non-solvent induced phase separation. In this composite architecture, PVA acts as a mechanically stable skeleton, while LS provides a high density of surface-accessible sulfonate groups (-SO 3 ) for cation-exchange adsorption. Subsequent crosslinking with epichlorohydrin stabilizes the three-dimensional network, minimizing swelling and ensuring structural integrity. Under optimized conditions (10 wt% PVA and 15 wt% LS), the resulting LS/PVA-AFs exhibit a highly porous skeleton, excellent hydrophilicity, and a strongly negative surface charge. Using lysozyme as a model basic protein, the fibers achieved a static adsorption capacity of 1726.34 mg/g, with over 95% capacity retention after ten regenerative cycles. When packed into a chromatography column, the LS/PVA-AFs demonstrate a high hydraulic flux of 77.65 L/h at 0.5 bar and exhibited a high dynamic binding capacity of 655.41 mg/g at 10% breakthrough. This work provides a robust and green platform for bridging the gap between high-flux throughput and high-capacity binding in next-generation downstream bioprocessing.

Although the Ti3C2 MXene has demonstrated exceptional promise for supercapacitor applications, its practical implementation is limited by its inherent tendency of undergoing restacking and oxidation. Herein, we propose a facile self-assembly strategy of in situ polymerization to construct lignosulfonate (LS)-modified polypyrrole (PPy)/MXene hybrid hydrogels with a hierarchical porous structure. The formed PPy nanoparticles and coating layer effectively prevent MXene restacking and oxidation, while enhancing electrical conductivity and electrochemical activity. Furthermore, LS contributes redox-active quinone groups, further promoting electron and proton storage and exchange. The hierarchical heterostructure provides continuous ion-diffusion pathways and exposes abundant electroactive sites, yielding a remarkable specific capacitance of 663.7 F g–1 at 0.2 A g–1 with 81.2% capacitance retention and 95.3% Coulombic efficiency after 5000 cycles at 2 A g–1. Assembled solid-state symmetric supercapacitors achieve an exceptional energy density of 29.3 W h kg–1 at 200 W kg–1 and maintain 12.4 W h kg–1 at an ultrahigh power density of 3200 W kg–1, alongside fairly good cycling stability (87.6% capacitance retention) and a Coulombic efficiency of 94.1% over 5000 cycles. These results highlight the multifunctionality of the LS component within the hybrid hydrogels─simultaneously stabilizing the structure, improving electrical conductivity, generating cross-links, and contributing toward pseudocapacitance─establishing LS-modified PPy/MXene hybrid hydrogels as high-performance electrode materials for advanced supercapacitor applications.

In modern society, with the rapid increase in energy consumption, there is a growing interest in the effective utilization of bio-resources. Biomass aerogels have considerable academic research value due to their eco-friendly attributes and renewable nature. In this work, sodium alginate (SA) and sodium lignosulfonate (SLS) are employed as the matrix, which are dually cross-linked with Ca 2+ and bis[tetrakis(hydroxymethyl)phosphonium] sulfate (THPS). Subsequently, a well-formed aerogel (CA-SP) is obtained through the lyophilization process. The formed dual crosslinking network and the “egg-box” structure endow the CA-SP aerogel with superior flame retardancy and thermal insulation properties, as evidenced by a limiting oxygen index value of 40.8%, achievement of the UL94 V-0 rating and low total heat release (1.35 MJ·m −2 ). Moreover, the THPS simultaneously endows the SA-SP aerogel with excellent flame retardancy and antimicrobial effect. The exceptional flame retardancy, smoke suppression capabilities, and antimicrobial effects of the CA-SP aerogel expand its prospects for application.

The application of chitosan (CS) film in active food packaging fields is greatly limited by their poor strength , antioxidant and barrier properties. Two nanoparticles , lignosulfonate (SLS) and bentonite (BT), were used together to enhance the food packaging properties of CS composite films in this work. A dense and robust multifunctional bio-based nanocomposite film with a pearl-like structure was successfully prepared. Results indicated that the introduction of SLS substantially better the strength, antioxidant, and UV-shielding capacities of CS composite film. The maximum tensile strength of the obtained nanocomposite film (SLS/BT/CS) reached 1.9 times of pure CS film. The SLS gave the composite film an excellent UV-shielding property (between 6.18–0.14% (T UVA ) and 0.32–0.06% (T UVB ) at 10–40 wt% SLS). The total phenolic hydroxyl group content of the composite film was significantly increased after adding SLS, and the DPPH· scavenging ability of SLS/BT/CS film was 5 times better than that of BT/CS film. The addition of BT bent the water vapor transport path in the film and created a hydrophobic surface , which in turn led to a significantly better water vapor barrier performance of SLS/BT/CS than pure CS films. The results of this work showed the great application potential of SLS/BT/CS nanocomposite film in the food packaging fields.

Creating durable flame retardancy, enhanced mechanical performance, and hydrophilic polyamide 6.6 (PA6.6) textiles via cost-effectiveness from sustainable renewable sources is a considerable challenge. This study introduces a pretreatment process involving the application of sodium lignosulfonate (LS) to the surface of PA6.6 fabrics, thereby enhancing their hydrophilic and flame-retardant properties. Subsequently, a layer-by-layer (LbL) nanocoating treatment is employed, utilizing renewable polyelectrolytes—chitosan (CS), LS, and poly (sodium phosphate) (PSP)—to create 8-bilayer (BL) and 4-quarda layer (QL) structures that further improve the hydrophilicity and durable flame resistance of PA6.6 fabrics. The combined LS-modified and LbL coatings notably increased the limiting oxygen index (LOI) values from 19.5 % to 22.5 %, eliminated melt dripping, and secured a V -1 rating in the vertical burning (UL-94) tests. Moreover, the treated fabrics exhibited a 43 % reduction in the peak heat release rate (PHRR) and a lower fire growth rate (FGR) of 0.84 W/g·s, with a significant increase in char yield% in both air and nitrogen (N 2 ) atmospheres. A cross-linked network structure is responsible for the superior hydrophilicity, enhanced tensile strength, and fabric softening properties. The self-crosslinking of sulfur-containing radicals with amide units ensures an anti-dripping performance that can withstand up to 30 home laundering cycles, demonstrating remarkable washing durability. However, a convincing approach has been developed for sustainable and high-performance materials for the textile industry, and a simple LbL technique using renewable polyelectrolytes that have traditionally been utilized in water treatment and food processing has been developed.

Electrically conductive hydrogel electrodes with high electrochemical activity are crucial for flexible supercapacitors. However, the sluggish electrochemical performance caused by the cold temperature still hinders their practical applications. Herein, we use ligninsulfonate sodium (LS) as a template to prepare a highly conductive polyaniline (PANI)-based electrode material, which is then incorporated into a chitosan (CS)/PAAM double-network scaffold to form an LS-PANI/CS/PAAM hydrogel. The as-prepared hydrogel not only exhibits excellent mechanical flexibility but also possesses antifreezing and antidrying properties due to the participation of the H3PO4 electrolyte. As a proof, the assembled LS-PANI/CS/PAAM supercapacitor achieves a superb-specific capacitance of 891 mF/cm2, an outstanding energy density of 65.9 μWh/cm2, and a wide working temperature window from −30 to 90 °C. In addition, the device showed efficient photothermal-stimulated self-heating ability, which could realize solar-thermal conversion capacitance enhancement. In the presence of 0.8 W/cm2 solar illumination, the device exhibits a considerable specific capacitance of 681 mF/cm2 at −30 °C, corresponding to a 30.2% improvement over the capacitance without solar illumination. In addition, the energy density of 60.5 μWh/cm2 is delivered at −30 °C, which is superior to that of most hydrogel SCs. Therefore, by developing a photothermal supercapacitor using solar energy sources, it is possible to mitigate the capacitance decay under low-temperature environmental conditions.

Sodium lignosulfonate (SL) was prepared from waste of cotton lignin (CL) through hydrothermal reaction method. Orthogonal experiment was designed with value of OIT as objective function. Polypropylene (PP) is a polymer produced by the addition polymerization of propylene. It is a white waxy material with a transparent and light appearance, which is widely used in food and pharmaceutical packaging. The results of GPC and TG analysis revealed that SL has stable thermal properties, which means that SL has the potential to be an antioxidant for PP materials. In addition, the scavenging effects of CL and SL were studied. The obtained results exhibited that the SL can obviously increase the scavenging effect on free radicals and it is a kind of new synthetic antioxidant with antioxidant property, which could effectively delay the oxidation of PP. Subsequent rheological experiments proved that the SL/PP sample can improve the heat-resistant oxygen performance of PP under the thermal oxygen shearing environment. Combined with the effect of SL on the mechanical properties of PP before aging, SL has a stabilizing effect on PP thermal oxygen aging.

Maximizing the use of waste is an important part of the strategy for sustainable development. Lignosulfonate , a waste product with sufficient reactive functional groups, can be used as reinforcing materials in polymer composites . In this work, composite hydrogels composed of lignosulfonate- graft -poly (acrylic acid) AA network and hydroxyethyl cellulose (HEC) polymer chains are synthesized through in situ polymerization and cross-linking reaction. The composite hydrogels have semi-interpenetrating network (semi-IPNs) structure, which is driven by the hydrogen bond interactions between proton-donating PAA and proton-accepting HEC. The mechanical properties of these composite hydrogels, including fracture stress, critical compression and elastic modulus and elongation are investigated by tensile measurements. These composite hydrogels exhibit higher toughness and extensibility compared to conventional PAA polymer hydrogels. Moreover, full recovery of their original shape after the removal of compression stress indicates their excellent shape-recovery property. Due to their porous structure , these hydrogels show stimuli responsive swelling properties in aqueous solution depending on the pH or ionic strength , which facilitate the repeating absorption and removal of dyes. Therefore, this work may open a new pathway to synthesize functional materials based on lignosulfonate.
