A new acrylic-lignosulfonate resin (ALR) was obtained by radical polymerization using calcium lignosulfonate (LS-Ca) and acrylic acid (AA) as raw materials. ALR was characterized using FT-IR, SEM, TG-DSC and N 2 adsorption–desorption surface area and pore size analyzer. Batch adsorption, including initial concentration, time, pH, dosage and temperature on the adsorption of crystal violet (CV) by ALR, was systematically studied. The ALR contained porous structure and the specific surface area of ALR was 190.55 m 2 /g with average pore diameter 11.34 nm. The kinetic and equilibrium data fitted into the pseudo-second-order model and Freundlich isotherm model, respectively. The adsorption process was slightly influenced in the range of pH=3–12. The maximum adsorption capacity of CV was found to be as high as 150.40±4.80mg/g for 24 h at 25 °C. Thermodynamic parameters were evaluated, and their values indicated that adsorption of CV on ALR was an exothermic process and spontaneous.

Recently, there has been a growing research interest on renewable composite due to sustainability concerns. This work demonstrated the possibility of using eucalyptus lignosulfonate calcium (HLS) particles as reinforcement in polyvinyl alcohol (PVA) matrix. 41% and 384.7% improvement of pure PVA tensile strength and Young's modulus were achieved with incorporation of 5 wt% HLS. The above results were ascribed to specific intermolecular interactions between HLS and PVA, suggested by the increasing PVA glass transition and crystalline relaxations temperature, depression of melting point with HLS incorporation. Moreover, this interaction was quantitatively determined by q value of −62.4 ± 10.0 in Kwei equation. Additionally, the remarkable red shift of wavenumber corresponding to hydroxyl group also indicated the formation of strong hydrogen bond in HLS/PVA blend. SEM characterization confirmed that HLS/PVA blends are at least miscible.

Lignin, an abundant natural polymer but presently under-utilized, has received much attention for its green/sustainable advantages. Herein, we report a facile method to fabricate lignosulfonate (LS) ionic hydrogels by simple crosslinking with poly (ethylene glycol) diglycidyl ether (PEGDGE). The as-obtained LS-PEGDGE hydrogels were comprehensively characterized by mechanical measurements, FT-IR, and SEM. The rich sulfonic and phenolic hydroxyl groups in LS hydrogels play key roles in imparting multifunctional smart properties, such as adhesiveness, conducting, sensing and dye adsorption, as well as superconductive behavior when increasing the moisture content. The hydrogels have a high adsorption capacity for cationic dyes, using methylene blue as a model, reaching 211 mg·g −1 . As a moist-induced power generator, the maximum output voltage is 181 mV. The LS-PEGDGE hydrogel-based flexible strain sensors exhibit high sensitivity when detecting human movements. As the hydrogel electrolyte, the assembled supercapacitor shows high specific capacitance of 236.9 F·g −1 , with the maximum energy density of 20.61 Wh·kg −1 , power density of 2306.4 W·kg −1 , and capacitance retention of 92.9% after 10,000 consecutive charge-discharge cycles. Therefore, this multifunctional LS hydrogels may have promising applications in various fields, providing a new platform for the value-added utilization of lignin from industrial waste.

The separation of oil components from oily sludge is an important component of soil remediation and energy recovery. Therefore, establishing a green and efficient separation technology is of great significance. In this study, oily sludge was separated using sodium lignosulfonate (SL) treatment. The effects of temperature, SL concentration, rotate speed, time, and pH on the oil removal rate were studied. The optimal conditions were as follows: temperature, 30 °C; SL concentration, 2.0 g·L–1; rotate speed, 200 rpm; time, 60 min; and pH 11. The maximum oil removal rate was 83.21%. The physicochemical properties of oily sludge were analyzed. The soil was looser, and the contact angle (55°) of the soil surface was reduced. Alkanes, aldehydes, ketones, carbonic acids, benzene rings, and alicyclic ethers were removed. The result shows that the SL treatment removed a wider range of petroleum hydrocarbon and had a stronger oil removal capacity. It provides a new method for the green and efficient separation of oily sludge.

In order to improve lignin-based materials’ utilization, the grafting mechanism of lignin was studied by investigating hydrogen peroxide (H 2 O 2 ) initiator's effect on the structure of eucalyptus lignosulfonate calcium (HLS). HLS was treated by low content of H 2 O 2 (H 2 O 2 /HLS wt = 1%, 2%, 4%) under various reaction temperature and time. Changes in HLS structure were investigated by difference UV, UV, FTIR, 1 H NMR, GPC and intrinsic viscosity. The results showed that though phenolic hydroxyl group (Ph-OH) of HLS was not oxidated to the quinoid structure, its content still decreased after treated by H 2 O 2 initiator. Meanwhile, the new aryl–alkyl ether structures and increased average molecular weight were observed. A radical coupling mechanism for the decreasing Ph-OH group's content was proposed, which radicals may terminate between phenoxy and benzyl radicals. In addition, the cleavage of methoxyl-aryl ether made a decline in the content of syringyl units, while that of guaiacyl, p -hydroxyphenyl units and free aromatic C-5 hydrogen increased when HLS reacted with H 2 O 2 .

Chitosan (CH) and chitosan/lignosulfonate composite (CH/LS) were selected as shell materials for microencapsulated red phosphorus (MRP). MRP samples of RP@CH and RP@CH/LS were prepared and applied as flame retardants for epoxy resin (EP). The microstructure, chemical composition and thermal decomposition of the as prepared samples were systematically characterized. The effects of red phosphorus (RP), RP@CH and RP@CH/LS on the flame retardance performance of EP and the mechanism were investigated in detail. The results showed EP containing 7wt% RP@CH/LS got the limited oxygen index value of 30.6 %, and passed V-0 degree in the vertical burning tests. The peak heat release rate of EP/7wt% RP@CH/LS decreased 59.7 % compared with that of neat EP in the cone calorimeter tests. The shell structures also improved the interfacial compatibility between RP and the organic substrates, which was illustrated by tensile strain tests and scanning electron microscope (SEM) observation.

The growing energy crisis has intensified the need for efficient energy storage solutions. Biomass has emerged as a promising resource for novel energy storage devices. Lignosulfonate, a byproduct of the forestry and pulp industries, contains quinone groups and has enormous potential for electrochemical energy storage. However, due to its poor electrical conductivity, this material must be combined with conductive materials to improve the energy storage efficiency. Carbon materials, particularly porous carbon, are ideal conductive substrates because of their high electrical conductivity, affordability, and ease of fabrication. This study demonstrates the synergistic effects of lignosulfonate/nanocarbon composites (LS/NC), in which heteroatom doping, high specific surface area, and quinone groups considerably enhance their electrochemical performance. Nanocarbon (NC) provides ion diffusion channels with low internal resistance and a large double-layer reaction area, promoting efficient electrolyte ion diffusion and transport. In addition, the introduction of oxygen and sulfur heteroatoms not only increases the material's hydrophilicity but also provides polar surfaces and accessible pseudocapacitive sites. Under acidic conditions, the LS/NC composite achieved a specific capacitance of 571 F g −1 at a discharge rate of 1 A g −1 —approximately double that of NC alone (279 F g −1 ). These findings provide notable advancements in the development of efficient energy storage devices.

Acrylic shape memory polymers rely on the rate of thermal-induced shape recovery as a key index that directly influences their effectiveness in applications that demand controllable deformation. Herein, varying concentrations of sodium lignosulfonate are added to a solution of methyl methacrylate (MMA) and polyethylene glycol diacrylate (PEGDA) during polymerization to modify the polymer network structure of MMA/PEGDA, thereby improving its thermotropic response. The results showed that incorporating 12 wt% lignosulfonate improved the shape recovery rate of SMP from 50% to 100%, while maintaining a tensile strength of 6.9 MPa. The LSMP’s storage module exceeds that of the SMP by over twofold at room temperature, and its energy release rate increases more rapidly with increasing temperature. The chemical bonding of lignosulfonate to PEGDA/MMA segments was found to improve its thermotropic response efficiency by adjusting the polymer network, as evidenced by multiple characterizations. This study highlights the potential to enhance the thermotropic response of acrylic SMP by adding lignosulfonate, while also offering new perspectives on lignosulfonate waste management.

Conductive polymer hydrogels for flexible supercapacitors usually contain nonconductive matrices (e.g., PVA, PAM), which hinder the electrochemical performance. This work presents a matrix-free strategy via supramolecular self-assembly, utilizing HEDP as a dual-functional dopant/cross-linker and lignosulfonate (LS) as a redox-active template. The incorporation of LS optimizes the nanostructure for faster ion transport while simultaneously contributing additional pseudocapacitance via quinone/hydroquinone redox couples. This supramolecularly assembled PANI/HEDP/LS (PHL) hydrogel demonstrates significant electrochemical advantages. At 0.5 A g–1, the PHL9 hydrogel electrode delivered a specific capacitance of 625 F g–1, exceeding that of the original PHL0 hydrogel without redox additives (419 F g–1). The PHL9 hydrogel electrode also exhibited an electrical conductivity of 86.51 S m–1, while maintaining stable cycling performance after 10,000 charge/discharge cycles (76.51% retention) and good flexibility, as 92.64% of the capacitance was still preserved after 200 bending cycles. All-hydrogel-state flexible supercapacitors (FSCs) constructed with PHL9 composite hydrogel electrodes delivered an energy density of 22.5 Wh kg–1 at a power density of 125 W kg–1, surpassing that of PHL0-based FSCs (16.2 Wh kg–1). Moreover, the device further maintained 80.75% of its initial capacitance after 10,000 charge/discharge cycles, indicating reliable long-term stability. Overall, these results indicate that the proposed strategy provides an effective route for developing high-performance composite hydrogel electrodes in wearable and flexible energy storage applications.

A high-energy ball milling strategy was developed to optimize nano titanium dioxide (nano-TiO2) through sodium lignosulfonate (SL)-mediated electrostatic surface modification. At 20 wt % nano-TiO2 and 5 wt % SL, the colloidal system achieved optimal stability with a sun protection factor (SPF) elevation from 15 to 17. Subsequent emulsion formulation with various aqueous phase to oil phase mass ratios (κ) yielded a Pickering emulsion at different pH values, demonstrating exceptional interfacial stabilization via nano-TiO2 and SL electrostatic assembly. The optimized TSL-4 emulsion (κ = 1:1, pH = 4) exhibited remarkable storage stability (keeping over 25 SPF value after 6 weeks of accelerated test) and thermal resilience (maintaining above 91% SPF retention through 10 freeze–thaw cycles.). Biological evaluations of TSL-4 (κ = 1:1) emulsion demonstrated no phototoxicity (irradiated vs nonirradiated viability difference < 2%), low cytotoxicity (90% HaCaT cell viability), and minimal cutaneous permeation (no nanoparticle accumulation in subcutaneous layers). The biomass-compound-modified nano-TiO2 system establishes a multifunctional sunscreen platform that synergistically integrates UV attenuation, colloidal stability, and biosafety.

Lignin-based dye dispersants (LDD), as one of the most common lignin resource end-application product, is difficult to meet the rapidly developing needs of modern fiber dyeing due to their inherent structural defects. The efficient upgrading and modification of LDD is of great significance to the value-added application of lignin resources and the expansion of LDD sinking market. In this study, using industrial kraft lignin as raw material, cashew phenol was introduced into lignosulfonate in the form of C C bonds by ingenious utilizing the structural characteristics of lignin disordered condensation. Aromatic ring in cashew phenol could provide sufficient sulfonic acid group grafting sites, while C 15 fatty chain could enhance steric hindrance effect. In the dispersibility test, the dispersing power showed 99.09 %, and the low/high temperature dispersion (LTD/HTD) were 5 s/4 and 6 s/4, respectively, higher than the dispersibility level of LDD in the market, has great commercial value and industrial potential. Combined with FTIR, 1 H NMR, GPC and ICP, the structural properties of lignin were analyzed in detail, and the degree of sulfonation-condensation was balanced-optimized. The C C bond condensation process between cashew phenol and lignin was revealed, and the mechanism of action on dye particles was elucidated.

With the rapid development of industry, dye wastewater increasingly damaged the ecological environment and human health. Therefore, the treatment of wastewater became an urgent environmental issue. In this paper, sodium lignosulfonate was modified with the Reimer-Tiemann reaction and then cross-linked with chitosan hydrochloride to prepare modified sodium lignosulfonate-chitosan hydrochloride (MSL-CHC) composite materials, which were characterized by infrared spectra (FT-IR), scanning electron microscope (SEM), Brunauer-Emmett-Teller (BET) surface area, and X-ray photoelectron spectroscopy (XPS). Then, the adsorption performance of MSL-CHC for Congo red (CR) was investigated under different conditions, including adsorbent dosage, adsorption time, inorganic salt ion species, ionic strength and adsorption temperature. The results showed that the adsorption was consistent with the pseudo-second-order kinetic model, indicating that chemical adsorption was dominant. The adsorption isotherm could be fitted as the Langmuir model, indicating monolayer chemical adsorption. Thermodynamics studies showed that the adsorption of CR was a spontaneous endothermic process. The maximum adsorption capacity for CR was 804.32 mg·g −1 . Furthermore, the adsorption capacity of different dyes, as well as the adsorption process in various inorganic salt solution, indicated that MSL-CHC composites had good universality, anti-interference ability and recyclability. The composite materials were environmentally friendly, pollution-free, and easy to obtain, which were ideal bio-based adsorption materials for removing dyes from water.
