Modulation of pore structure and heteroatom doping are very important strategies to improve the electrochemical properties of carbon electrode materials. This report investigates the use of biomass-derived nitrogen-doped porous carbon materials to address the challenge of the specific capacitance and energy density in supercapacitors. Nitrogen-doped three-dimensional hierarchical porous carbon materials were prepared using a polyacrylonitrile/sodium lignosulfonate composite monolith as a precursor by thermally induced phase separation and subsequent carbonization/activation. This method precisely controls the structure and surface properties of porous carbon materials by regulating the structure of the precursor and situ doping of nitrogen, which is a valuable strategy for the controllable regulation of the pore structure for nitrogen-doped porous carbon materials. The resulting carbon material displayed excellent capacitance performance, exhibiting a high specific capacitance of 325.7F g -1 at a current density of 0.5 A/g, maintaining initial capacitance retention of 90.1 % at a current density of 5 A/g after 10,000 cycles. When investigated for practical applications, the assembled supercapacitor device had a higher energy density (9.88 W h kg - 1 ), which is higher than commercial carbon-based supercapacitors.

Lignosulfonate (LS) is used to improve asphaltic aging resistance owing to absorbing ultraviolet (UV) light and trapping free radicals. However, excessive addition of LS disrupts uniform dispersion in the asphaltic matrix due to polarity mismatch, causing aggregation, phase separation, and matrix hardening, which collectively reduces anti-aging effectiveness. Herein, we demonstrate a strategy of diisocyanate to enhance LS on asphaltic compatibility with asphalt by synergistically reducing hydrophilic groups and surface free energy. In detail, three diisocyanate functionalized LSs (DFLSs) were prepared via covalent binding of hydroxyl and isocyanate groups, and their structural properties were characterized using various techniques. The results indicated that DFLS had larger particle sizes, greater hydrophobicity, and improved UV absorption than LS. Subsequently, DFLS was utilized to modify asphalt (DFLS-MA), demonstrating superior aging resistance compared to LS-modified asphalt (LS-MA) and pristine asphalt (PA). Beyond the compatibility test, the interaction between DFLS and asphalt was elucidated using molecular simulations (MS). Through functioning of diisocyanates, the surface energy value of LS declined from 34.034 to 8.470 mJ/m 2 maximumly, stating that the aggregation of LS was inhibited markedly. Meanwhile, Binding energy calculations revealed that DFLS exhibited higher absolute values than LS, indicating that the functionalization of improved LS dispersion in asphalt and contributed valid aging protection. Furthermore, 4,4′-diphenylmethane diisocyanate (MDI) illustrating the most effective enhancement among all, highlighting that the introduction of benzene ring was pivotal in improving LS compatibility with asphalt. This finding presents a novel approach to enhancing asphalt aging resistance through the structural organization of lignin materials.

Gel-based adhesives show promising prospects in epidermal bioelectronics because of their potential applications in physiological signal collection and electrical stimulation. An ideal epidermal adhesive should exhibit robust adhesion for lamination and poor adhesion for easy peeling, in addition to strain-insensitivity in electrical properties for motion-artifact-free physiological signal collection. Here, lignosulfonate-derived organohydrogel adhesives with anisotropic and tunable adhesion, together with unprecedented strain-insensitivity are synthesized. The organohydrogel exhibits a high interfacial toughness of 728 J m −2 on fresh porcine skin, while the adhesion can be screened by covering a denatured silk fibroin. An anisotropic adhesive with an adhesion heterogeneity is designed, showing a 14.2-fold difference in adhesion strength along two different directions for on-demand attachment and removal. The adhesive can transform into a highly porous structure, which has only a 3% resistance increase at 100% strain. The strain-insensitivity of the adhesive lies in the strong interaction of ions and the 3D porous structure, which enables motion-artifact-free and high-quality electrophysiological signal collection within the strain range of the human skin. The lignosulfonate-derived on-demand organohydrogel adhesive is expected to be used in epidermal bioelectronics, human-machine interaction, metaverse, and beyond.

A one-pot clean preparation procedure and catalytic performance of platinum nanoparticles (NPs) reduced and stabilized by sodium lignosulfonate in aqueous solution are reported. No other chemical reagents are needed during the metal reduction and stabilization step, thanks to the active participation of sodium lignosulfonate (SLS). UV–vis, Fourier transform infrared (FT-IR), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), 1H NMR, 195Pt NMR, and two-dimensional heteronuclear single-quantum coherence (2D HSQC) NMR studies were thoroughly performed to analyze the formation, particle size, and main lattice planes of NPs, the valence-state changes of the metal, and structural changes of SLS. An ecofriendly selective synthesis of cis-pinane from an abundant renewable natural resource, α-pinene, was developed in the presence of the prepared Pt NP aqueous system. Furthermore, this catalyst system was proved to show easy recovery and stable reusability by five-run tests. The synergistic effect of SLS reduction and stabilization not only avoided the introduction of conventional reducing agents and stabilizers but also made full use of the byproducts of the pulp and paper industry. This proved to be an environmentally friendly method for converting the natural resource α-pinene to cis-pinane.

Because of the special lamellar structure, numerous pores, and large effective specific surface area, the two-dimensional porous carbon material is very beneficial for the storage and transmission of energy. Herein, a facile method for preparing two-dimensional porous carbon nanosheets from sodium lignosulfonate with excellent electrochemical performance is reported. In this study, porous carbon nanosheets (PCNs) were obtained by the carbonization of the material, in which sodium lignosulfonate was coated on the boric acid surface, followed by activation by potassium hydroxide. By changing the thickness of the lamella structure and the subsequent activation process, the hierarchical pore structure was prepared in an effectively controlled manner. When the ratio of boric acid to sodium lignosulfonate was 4 : 1, the material possessed an ideal architecture and the best electrochemical performance. Porous carbon nanosheets with reasonable pore size distribution could increase the electron transfer rate between the electrolyte and the electrode material. The capacitance of PCN-4 was found to be 198 F g−1 at 1 A g−1 and could still maintain about 90% when the current density was increased to 20 A g−1. In addition, excellent cycling stability was obtained, and the capacitance retention was more than 91% after 5000 cycles under 10 A g−1. Thus, this research discovered a facile way to utilize sodium lignosulfonate, which is used for biomass conversion and renewable energy utilization.

Sodium lignosulfonate (LS) was modified by polypropylene glycol diglycidyl ether (PPGDE) for the preparation of a surfactant (GLS), and firstly used for detergent builder. The effects of PPGDE content on the reaction and the properties of GLS were investigated. The structure of GLS was studied by Fourier transform infrared spectra (FTIR), ultraviolet spectrophotometer (UV), and gel permeation chromatography (GPC). The surface tension, critical micelle concentration (CMC), emulsifying ability, lime soap dispersing power (LSDP), and detergency were characterized. The results showed that GLS had higher surface activity and better emulsifying ability, LSDP, and detergency than that of LS. After decolorized by H2O2, the whiteness retention value of decolorized LS on white cloth reached 91.9%, while that of decolorized GLS increased up to 99.4%. These results suggested that the decolorized GLS may provide a new perspective for detergent builders.

Porous carbon can be widely applied in energy ranging from lithium-ion batteries to supercapacitors . We here propose a novel hierarchical porous graphitic carbon (HPGC) monolith to replace conventional activated carbon for achieving excellent electrochemical performance. In this monolith structure made from the cross-linking of lignosulfonate without any templating agent, the nanoscale core is composed of porous amorphous carbon , while the microscale shell is formed by graphitic carbon and generated within mesoporous wall of HPGC. As evidenced by cyclic voltammetry , the abundant porosity and the high surface area not only offer sufficient reaction sites to store electrical charge physically, but also accelerate the liquid electrolyte to penetrate the electrode and the ions to reach the reacting sites. Of special interest is the fact that HPGC monolith maintains mesoporous without extrinsic template agent.

A novel carbon fiber precursor was prepared from lignosulfonate (LS) with acrylonitrile (AN) via a two-step process consisting of esterification and free radical copolymerization. The LS–AN copolymer was characterized by FTIR, 1H NMR, 13C NMR, UV, GPC, DSC, and TG. Continuous long precursor fibers with a brown color and a dense structure were prepared from the LS–AN copolymer by a wet spinning technique. Carbon fibers that were free of any visible voids and other defects were also obtained from the precursor fibers by thermal stabilization and carbonization. This study provided a promising way to develop partially biobased carbon fibers with desired mechanical properties for industrial applications.

We report a simple method to synthesize spherical and irregular sodium lignosulfonate (SLS)-stabilized zinc oxide (ZnO) nanoparticles using water as a solvent, SLS as a stabilizing agent, and sodium hydroxide as a precipitation agent. The presence of SLS on the surface of ZnO nanoparticles can improve the dispersion of the nanoparticles and make them negatively charged. The negatively charged SLS-stabilized ZnO nanoparticles can be deposited onto cellulose paper through a layer-by-layer (LBL) approach. The resultant cellulose paper samples, coated with ZnO nanoparticles, show good antibacterial activity against both Gram-positive Bacillus subtilis and Gram-negative Escherichia coli.

The long-term stability of nano disperse dye slurry is a problem in industry. In this work, high molecular-weight polyether amine-bridged lignosulfonates (PEABLs) were prepared to improve the adsorption strength of dispersants on dye surfaces, and thus the stability of nano disperse dyes. Specifically, the molecular simulation software was firstly used to analyze the adsorption of PEABL on dye surfaces. Then, PEABLs with different molecular weights were synthesized and characterized by adjusting the addition of polyether amine. Next, nano disperse dyes were prepared using PEABLs and the optimum grinding conditions were explored and obtained. Finally, PEABL3 was determined to the optimum dispersant, having a smallest particle size (168 nm) and highest stability, comparable to the commercial Reax 85A dispersant and basically satisfying the demand of nano disperse dyes required in digital transfer printing technology. Quartz crystal microbalance (QCM), atomic force microscopy (AFM) and zeta potential results showed as the molecular weight of PEABL increased, the adsorption amount, adsorbed layer rigidity, adsorption force and absolute zeta potential value all firstly increased due to the enhanced hydrophobic interaction, and then decreased due to the formation of complicated three-dimensional network structures caused by the crosslink of lignosulfonate molecules. A maximum was observed for PEABL3.

Lignosulfonate/polyaniline (LS/PANI) nanocomposite adsorbent materials were prepared by the chemical polymerization of lignosulfonate with an aniline monomer as a dopant and structure-directing agent, and the adsorption behavior of dyes as well as heavy metal ions was investigated. LS/PANI composites were used as dye adsorbents for the removal of different cationic dyes (malachite green, methylene blue, and crystal violet). The adsorption behavior of LS/PANI composites as dye adsorbents for malachite green was investigated by examining the effects of the adsorbent dosage, solution pH, initial concentration of dye, adsorption time, and temperature on the adsorption properties of this dye. The following conclusions were obtained. The optimum adsorption conditions for the removal of malachite green dye when LS/PANI composites were used as malachite green dye adsorbents were as follows: an adsorbent dosage of 20 mg, an initial concentration of the dye of 250 mg/L, an adsorption time of 300 min, and a temperature of 358 K. The LS/PANI composite adsorbed malachite green dye in accordance with the Langmuir adsorption model and pseudo-second-order kinetic model, which belongs to chemisorption-based monomolecular adsorption, and the equilibrium adsorption amount was 245.75 mg/g. In particular, the adsorption of heavy metal ion Pb2+was investigated, and the removal performance was also favorable for Pb2+.

Chitosan is a desirable alternative for petroleum-derived packaging materials, but the unsatisfactory performance of most chitosan composites drastically impedes their practical application. In this work, a facile physical blending strategy was selected to prepare chitosan-based composite films with good properties utilizing sodium lignosulfonate as a reinforcing agent. The effects of sodium lignosulfonate addition on the barrier performance, antioxidant activity , UV-blocking, and mechanical properties of the composite films were evaluated. The enhancement mechanism of sodium lignosulfonate on the structural and functional properties of the membranes was also investigated. The results show that chitosan mixed with sodium lignosulfonate exhibited a higher tensile strength (∼75Mpa), improved barrier property (OTR and WVTR are 4.8 g·m −2 ·d −1 and 415 g·m −2 ·d −1 , respectively), increased free radical scavenging activity (29.9 %), and enhanced UV-blocking ability (95 %) compared to pure chitosan film. Strong electrostatic interaction and hydrogen bonding between monodispersed sodium lignosulfonate and chitosan have an essential effect on the performance of composite films. The application of sodium lignosulfonate as a reinforcing material is both environmentally friendly and economically viable, showing promising potential for use in food packaging applications.
