Supercapacitors, known for their long cycle life and high-power density, are pivotal in various industrial and everyday applications. Addressing the dual challenges of green chemistry and the high-value utilization of lignin, this study introduces a novel synthesis process of carbon aerogels. These aerogels incorporate temperature-responsive carbon nanotubes (CNTs), synthesized via a one-pot method using magnesium lignosulfonate as precursor. Notably, the optimized carbon aerogel (AC-600) demonstrates a specific capacitance of 369 F g −1 at a current density of 1 A g −1 and retains 100 % capacitance after 20,000 charge/discharge cycles at 10 A g −1 . It also achieves an energy density of 17.6 Wh kg −1 and a power density of 489.9 W kg −1 . This paper proposes a novel strategy of replacing randomly dispersed carbon nanoparticles with self-synthesized, temperature-responsive CNTs, enhancing the structural integrity of honeycomb lignin-based carbon aerogels. This innovative approach opens new avenues for the efficient use of lignin-based aerogels in energy storage technologies.

Microplastic contamination of low-density polyethylene mulch and nutrient loss from fertilizers present significant challenges in the crop-growing. In this study, the focus was on creating a biodegradable film that combines the advantages of plastic film, thermal insulation and water retention, as well as the controlled release of fertilizer. A key innovation was the efficient introduction of low molecular weight and low dispersibility of poplar lignin into chitosan and polyvinyl alcohol matrices. The lignin was extracted using deep eutectic solvents of binary carboxylic acids (choline chloride and maleic acid). The refined lignin was used as a superhydrophobic additive to improve the mechanical properties, hydrophobicity, and controlled nutrient release properties of the films through cross-linking. The mulch attained a tensile strength of 37.6 MPa, an elongation of 644.1 %, and a precise release of 53.1 % urea over 30 d at the ideal lignin content ratio (10 %). Furthermore, the film proficiently regulated soil temperature and moisture content. Successful enhancement of cabbage growth was achieved by actual measurements. This discovery provides innovative ideas for the development of nutrient slow-release high-strength integrated agricultural mulching films to promote sustainable, high-quality green agriculture.

Modifications of urea-formaldehyde (UF) resin to achieve better bonding performance and lower formaldehyde emission are still an alluring task in the wooden composite industry. Herein, by strategically constructing a photocatalytic oxidation system relying on carbon dot-catalyzed peroxymonosulfate (PMS) activation, we confirmed that Kraft lignin can be readily oxidized to potent modifiers for improving the bonding performance of low-molar-ratio UF resin (F/U = 0.95). We found that the oxidation system consisting of carbon dots and PMS in a mass ratio of 1:20 revealed optimal efficiency in the oxidative valorization of lignin by primary cleavage of β–O–4 linkages, resulting in a remarkable reduction of molecular weight from 2026 to 679 Da. Meanwhile, lignin side-chain oxidation triggered by radicals (mainly involving sulfate radicals) also contributed largely to the transformation of S units to G and H units via demethoxylation, and the reaction patterns conferred the oxidation products an increased amount of aliphatic OH and phenolic OH. In comparison with untreated lignin, the lignin-degraded fragments promised relatively higher hydroxymethylation efficiency and enhanced chemical compatibility in the UF resin synthesis system, fostering the formation of copolymers containing phenolic-like moieties and branched polymer structures. Profiting from this structurally homogeneous modification of oxidized lignin, the copolymer resin not only revealed comparable storage stability to the UF resin but also possessed enhanced bonding performance on the premise of rather low formaldehyde emission, and plywood panels bonded with the lignin-modified resin exhibited a higher tensile shear strength of 0.81 MPa, which was a 58.8% increase with reference to the UF resin-bonded panels, and as a result complied with the relevant national standard (≥0.7 MPa). Overall, the lignin photocatalytic oxidation strategy proposed in our study would open a new avenue for providing biobased and potent modifiers in the production of wood adhesives.

Environmentally sustainable, non-toxic, and harmless multifunctional cotton fabrics, which are endowed with antioxidant and UV-resistant properties, exhibit considerable potential for applications in food protection and packaging. Consequently, there is an imperative need for the advancement of novel coating systems that can endow cotton fabrics with supplementary functional properties. Bamboo ethanol lignin (EL) was synthesized using a clean ethanol pulping process, and a multifunctional coating of EL was fabricated through a one-pot dipping method. In brief, EL interacts with cotton fibers via hydrogen bonding and physical adhesion, and the optimized sample, designated as Cotton@EL 1 , demonstrates outstanding antioxidant and UV-blocking properties. Compared to EL 0 , EL 1 exhibited a substantially higher antioxidant efficiency of 80.3 % and effectively blocked both UVA (99.99 %) and UVB (100 %) radiation. Furthermore, Cotton@EL 1 exhibited a UPF value of 48.2, with UV transmittance below 3 %, showcasing exceptional UV protection performance. In conclusion, this study presents a novel approach for the utilization of high-value wood materials in the development of environmentally sustainable, non-toxic, and multifunctional food protection and packaging fabrics.

An information encryption device using shape memory cellulose acetate (CA) as matrix, and lignin as photothermal agent was developed. Such information encryption was chiefly composed of two steps, that is, information concealing by fixing temporary shapes and information decryption by restoring original shape based on preset sequential lighting commands. This film device was fabricated readily by solution blending. Further related analyses on the photo-assisted shape memory mechanism of such composites were carried out. Compared to other samples, the CA/lignin-3 composites possessed the most excellent shape memory properties as its shape recovery angle of 180° and shape fixation angle of 30°. It had good mechanical, thermomechanical, and superior photothermal conversion properties. The elongation at break and tensile strength was 24% and 4.5 MPa, the glass transition temperature was 30–130°C. The results of the Fourier transform infrared and Ultraviolet–Visible spectra illustrated the tight relationship between conjugated chromophoric systems and photothermal conversion of composites.

To solve the poor absorbance on ultraviolet A (UVA) radiations and dark color, alkali lignin (AL) was modified via atom transfer radical polymerization (ATRP) grafting of 2-4-benzoyl-3-hydroxyphenyl acrylate (BHA). The color of AL was whitened 86% and the UVA/UVB absorbance ratio of AL-g-BHA improved to 1.2, while the reported highest value was 0.9. The excellent UV-blocking performance of AL-g-BHA was demonstrated in sunscreen. Sun protection factor (SPF) value of the sunscreen containing 10 wt % of optimal AL-g-BHA reached 59. Nanoscale AL-g-BHA normal and reverse micelles (LBNM and LBRM) were fabricated to investigate the effect of microstructure on the sunscreen performance. When BHA chains were packed inside, the SPF value of sunscreen containing 10 wt % of LBNM decreased to 28. In contrast, the SPF value of sunscreen containing 10 wt % of LBRM with BHA chains distributing on the surface was up to 244. Both AL-g-BHA and corresponding micelles exhibited good biocompatibility.

Flexible electric-heating materials (EHMs) with mechanical toughness and stability are in high demand in areas of portable heating elements; however, they are still hard to achieve. Here, strong and tough aramid nanofiber (ANF)/graphene composite membranes were fabricated with the help of interfacial lignin bonding through a noncovalent interaction-triggered “bridging” strategy. The as-prepared membranes (ANF-Lx-Gy) exhibited a maximum mechanical strength of ∼122.5 MPa, a maximum toughness of ∼377.2 MJ/m3, and also promising stabilities in commonly used solvents. Ascribing to the uniform distribution of graphene, the composite membranes presented enhanced conductivity (∼278 S/m) and demonstrated both high efficiency and stability for Joule heating performance (e.g., reaching ∼165 °C under an input voltage of 20 V within 5 s, eventually stabilizing at ∼200 °C, and remaining stable after 12 h of Joule heating). Besides the Joule heating application under low temperatures (e.g., joint worming below 100 °C), the stability of ANF-Lx-Gy also endowed them with favorable performances under high temperatures (e.g., deicing beyond 100 °C). Thus, this work paved a feasible way to develop ANF-based membranes that were strong and stable as flexible EHMs.

Many strategies have been proposed to produce arenes from lignin as liquid fuel additives. However, the development of these methods is limited by the low yield of products, low atom utilization, and inefficient lignin depolymerization. Herein, we develop an energy-efficient synthetic method for the production of high-carbon-number arenes from sustainable lignin with a total yield of 23.1 wt%. Particularly, high carbon number arenes are obtained by fully utilizing the formaldehyde stabilizing additive and the methoxy group in lignin. The process begins with the reductive depolymerization of formaldehyde-stabilized lignin, followed by transmethylation between lignin monomers over Au/Nb 2 O 5 catalyst, and the Ru/Nb 2 O 5 -catalyzed hydrodeoxygenation. This work demonstrates the potential of value-added arenes production directly from lignin.

The performance of electrodes is a key factor affecting the development of smart fabrics. The preparation of common fabric flexible electrodes has defects such as high cost, complicated preparation, and complex patterning that limit the development of fabric-based metal electrodes. Therefore, this paper presented a simple fabrication method for preparing Cu electrodes using selective laser reduction of CuO nanoparticles. By optimizing laser processing power, scanning speed, and focusing degree), we prepared a Cu circuit with an electrical resistivity of ∼ 5.53 µΩ.m. Based on the photothermoelectric properties of Cu electrodes, a white light photodetector is developed. The detectivity of the photodetector reaches ∼2.14 mA/W at a power density of 10.01 mW/cm2. This method is instructive for preparing metal electrodes or conductive lines on the surface of fabrics, and provides specific techniques for manufacturing wearable photodetectors.

Polyvinylpyrrolidone (PVP) is an antifouling polymer to resist the adsorption of protein on solid surface. Effects of PVP on the enzymatic hydrolysis of pretreated lignocelluloses and its mechanism were studied. Adding 1 g/L of PVP8000, the enzymatic digestibility of eucalyptus pretreated by dilute acid (Eu-DA) was increased from 28.9% to 73.4%, which is stronger than the classic additives, such as PEG, Tween and bovine serum albumin. Compared with PEG4600, the adsorption of PVP8000 on lignin was larger, and the adsorption layer was more stable and hydrophilic. Therefore, PVP8000 reduced 73.1% of the cellulase non-productive adsorption on lignin and enhanced the enzymatic hydrolysis of lignocelluloses greatly.

Water-soluble synthetic poly(vinyl alcohol) (PVA) polymers can be used as a raw material for high-performance solution-spun fibers. To enhance the biodegradability and physical properties of PVA fibers, lignin has been considered a low-cost, biobased filler/additive for PVA fibers. However, its amorphous structure and hydrophobic nature cause difficulty in developing lignin-reinforced PVA high-performance fibers due to the poor compatibility of amorphous lignin and linear semicrystalline hydrophilic PVA. Herein, the graft copolymerization of organosolv lignin (OL) and acrylic acid (AA) was performed at different reaction durations to yield hydrophilic lignin copolymers, which had enhanced compatibility with polar synthetic PVA. Chemically modified OL with reaction durations of 0, 12, and 24 h was incorporated into PVA fibers by gel spinning. With 5% modified OL from 24 h of reaction time, the composite fibers had an excellent tensile strength of 1.15 GPa, which was 61.4% higher than that of neat PVA fibers. This fiber’s Young’s modulus (13.09 GPa) and toughness (26 J/g) were also substantially enhanced when compared with those of the neat PVA fibers (Young’s modulus of 8.97 GPa and toughness of 18.09 J/g). This work enables the high-value utilization of a modified lignin filler in synthetic fibers for potential applications in industrial or technical textile fields.

Highly reactive polyols were prepared from modified acetic acid lignin (AAL) by a two-step combination of mild hydrothermal degradation and hydroxylation. The AAL-based polyols became relatively reactive and compatible with diisocyanate, with a reduction in the number average molecular weight (M n ) from 2923 to 684 g/mol and an increase in the hydroxyl content from 5.21 to 9.13 mmol/g. The mechanical performance and thermal properties of the AAL-based polyurethane elastomers (LPUEs) strongly depended on the molecular weight and hydroxyl content of the AAL-based polyols in the partial substitution of polytetramethylethylene ether glycol (PTMEG). This study proposed the prospective utilization of AAL as an alternative resource in the synthesis of polymers and biomaterials. © 2021 Society of Industrial Chemistry and John Wiley & Sons Ltd.
