Producing room temperature phosphorescent materials from natural sources is essential for sustainability. However, either toxic chemical reagents or complicated processing is still required to produce such phosphorescent materials derived from natural resources. Here, we produce sustainable room temperature phosphorescence (RTP) materials from wood and sugar. Specifically, sugar is introduced into a wood matrix, which confines the lignin in the wood matrix in situ . As a result, the treated wood (sucrose wood [S-wood]) exhibited RTP emissions with a lifetime of ∼284.4 ms. Life cycle carbon analysis indicates that ∼8.1–11.2 kg CO 2 is produced during the preparation of S-wood, which is lower than for other similar materials. Moreover, the S-wood could be naturally degraded in the soil over 40 days. As a demonstration of the practical potential, S-wood is used for visual decorations and anti-counterfeiting applications.

Lignin is a natural phenolic polymer characterized with renewable, sustainable and biocompatible, but yet remain underutilized. In the post-pandemic era, people are conventionally reusing mask but without any disinfections to prevent infection of virus in public places, which could lead to accumulation of bacteria and secondary infections. The development of antibacterial mask from lignin would simultaneously address the hygiene issues of used mask due to microbe accumulation and provide novel approach for lignin valorization. Herein, lignin/copper nanoparticle with excellent water dispersibility, antibacterial activity, and non-cytotoxicity was synthesized by in situ reduction of copper ions in lignin nanoparticles. The structure of lignin/copper nanoparticle, and antibacterial performance of the mask were thoroughly explored to understand the key factors to tune the process. Antibacterial mask was then prepared by simple dip coating of the lignin/copper nanocomposite onto the middle layer of a mask, which could effectively prevent the penetration of bacteria from the outer layer into the inner layer. The results of this study provide a feasible approach to prepare antibacterial mask using plant-derived, sustainable, and cheap raw material, namely lignin, which facilitate the high value valorization of lignin.

Polyurethane (PU) has become one of the most widely used materials in the industrial field due to its excellent performance and wide range of applications. The increasing consumption of polyurethane materials has resulted in significant polyurethane waste. We can recycle waste polyurethane to obtain recycled polyurethane, but to make the recycled polyurethane meet different performance requirements in terms of utility and cost and enable the recycled polyether polyol to be further applied to high-end applications, it is necessary to improve the use value of recycled polyether polyol. In this paper, self-made Fluorodiol was added to the degradation process of waste polyurethane to obtain fluorinated regenerated polyether polyol. Recycled fluorinated polyurethane with excellent performance was prepared using fluorine-containing recycled polyether polyol. The regenerated fluorinated polyether polyols were characterized by infrared spectroscopy, viscosity, hydroxyl value, and GPC molecular weight distribution. The density, apparent morphology, water absorption, mechanical strength, thermal conductivity, and thermal stability of RFPU rigid foams with different fluorine contents were studied by scanning electron microscopy. The results show that when the addition of Fluorodiol was 8% of the mass of waste polyurethane, the density was 41.2 kg/m3, the immersion loss rate was 2.125%, the compressive strength was 0.315 Mpa, and the thermal conductivity was 0.0227 W/m·K. The RFPU prepared by Fluorodiol has low surface energy, good compressive strength, hydrolysis resistance, and is expected to be widely used in special insulation materials. Thus, the sustainable recycling of polyurethane is achieved.Keywords:fluoroalcohol;waste polyurethane;recycled polyurethane;recycling;sustainable material

How to efficiently utilize fast-growing timber to create sustainable materials with excellent mechanical properties is important for resource utilization and environmental protection. Here, a simple yet efficient approach to construct cellulose-based sustainable materials through robust and effective microscopic interface design inspired by nacre was developed. A 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO) -oxidized wood after delignification and TEMPO-oxidation as the “brick”, then impregnated it with PVA as the “mortar”, and added borax as the cross-linking agent. This matrix was hot-presseed to produce a borax and PVA reinforced TEMPO-oxidized wood (BPTW) with “brick and mortar” structure, synergistically reinforced through hydrogen and covalent bonding. The results show that the BPTW has higher tensile strength (234 MPa), higher flexural strength (224 MPa), better thermal stability, flame retardancy, and water resistance compared to natural wood. Additionally, the entire process does not involve the use of adhesives, which reduces energy consumption and provides a methods for producing a lightweight, high-strength,and large-scale sustainable material.

With pressing environmental concerns and incessant depletion of fossil reserves, producing sustainable polymeric materials to become a research target. In this work, we prepare a bio-based polymer from a naturally occurring monoterpene (β-myrcene) and sulfur dioxide which can be captured from industrial waste gas. The structure of the synthesized polymer was ascertained by IR and NMR. The initiator initiated poly(myrcene-co-SO 2 ) possesses four kinds of microstructure, 1,4-cis and 1,4-trans are the main structures, and the contents of 1,2-vinyl and 3,4-addition microstructure are extremely low. Solubility behavior, thermal degradation and optical properties of poly(myrcene-co-SO 2 ) were characterized by theoretical solubility parameter, TG and Abbe-type refractometer. Moreover, we report the adhesive properties of the polymer on glass, wood, aluminum and copper. Due to hydroxyl groups on the surface of the material, poly(myrcene-co-SO 2 ) exhibits outstanding adhesion properties.

Flexible electronic skin (e-skin) with multimode broad-range pressure sensing and high sensitivity is highly desirable for robotics, artificial intelligence and human–machine interaction applications. Most research on e-skin has focused on improving the sensitivity of sensing layers interfaced with an electronic output device, with only a limited number of studies focused on user interfaces based on a human-readable output. Moreover, naturally degradable materials are receiving increasing attention for e-skin. Herein, inspired by a bioluminescent noctiluca, a wood-based e-skin with instrument- and naked eye-readable characteristics was sandwich assembled using silver nanowires and a super-flexible transparent wood (STW) film as an electrode and a pyramidal microstructure polydimethlysiloxane film as a stimuli-responsive layer. The electrode was prepared by depositing silver nanowires on the surface of the STW film through a Meyer rod coating method. The film demonstrated outstanding performance with high transmittance (91.4%), a small curvature radius (2 mm) and excellent sheet resistance stability even after greater than 1500 bending cycles. The e-skin showed notable changes in electroluminescence from 0 to 150 kPa (where humans feel pain) and the sensitivity remains larger than 0.15 kPa −1 over the broad pressure range. The sensitivity in capacitance exhibited high sensitivity at 1.01 kPa −1 in the low-pressure regime, meanwhile, the luminescence exhibited a maximum value at 1.28 kPa −1 at medium pressure. Furthermore, the e-skin accurately mapped the spatial distribution of static and dynamic pressures through optical sensing. This work not only improves the sustainable development of materials in electrodes but also illustrates the potential of utilizing natural wood in high value-added e-skin.

The separation of oil/water mixture by the use of selective absorption materials has been currently studied most wildly. However, the safe disposal of the absorbent waste is challenging. Here, degradable polyhemiaminal (PHA) aerogel was fabricated by one-step precipitation-polymerization. The resulting PHA aerogels showed low density, hydrophobicity, and high specific surface areas. These characteristics, together with the porous structure, imparted it with outstanding properties of oil/water separation. More interestingly, a device made of PHA aerogel can automatically collect gasoline on the water surface without external forces. Furthermore, PHA aerogel exhibited rapid degradation after use, and major raw material for synthesis of PHA aerogels is readily recoverable and further recycles. This work provides simple, environmentally friendly, and sustainable materials for oil/water separation.

Developing green 3D porous materials integrating multitasking environmental remediation with high efficiency and reusability is considered to be a promising sustainable approach and is urgently required. Herein, we have successfully prepared a facile, ecofriendly, and robust multifunctional composite sponge of carbon nitride (CN) nanosheets wrapping an elastomer polydimethylsiloxane (PDMS) skeleton without harsh treatments. The composite sponge (CN@PDMS) exhibits excellent hydrophobic and superoleophilic properties with a water contact angle of 133.2°. This sponge also shows high selective absorption of organic solvents and oils with high recyclability after 10 absorption cycles. Furthermore, the CN@PDMS sponge has a high ability for demulsification of the oil-in-water emulsion as well. The as-prepared sponge displays high thermal stability, retaining 82.16% of its original weight up to 550 °C, and extraordinary prolonged stability in harsh corrosive solutions over 35 h compared with the pristine PDMS sponge. Additionally, the CN@PDMS sponge exhibits a high ability for adsorption and photodegradation of rhodamine B under visible light irradiation with self-cleaning and high reusability over 5 runs. Such a sustainable strategy would provide new ways for broad environmental applications.

Recent advances in medical plastics highlight the need for sustainable materials with desirable elastic properties. Traditional polyester elastomers have been used as alternatives to polyvinyl chloride (PVC) due to their biocompatibility and adjustable mechanical properties. However, these materials often lack the necessary stability and toughness for reliable medical applications. To address these issues, this study introduces renewable 1,12-dodecanedioic acid (DA) to create a copolymer with diols, resulting in a structure akin to polyolefins. This innovative approach significantly enhances toughness by regulating chain segment lengths and integrates high performance with sustainability. The resulting bio-based elastomer exhibits remarkable biocompatibility and elastic recovery (69.0%). This work represents a significant advancement in the development of eco-friendly materials suitable for medical device applications, with potential implications for tissue engineering and other healthcare technologies.

Electromagnetic-interference (EMI) shielding materials that are green, lightweight, and with high mechanical properties need to be urgently developed to address increasingly severe radiation pollution. However, limited EMI shielding materials are successfully used in practical applications, due to the intensive energy consumption or the absence of sufficient strength. Herein, an environmentally friendly and effective method was proved to fabricate wood-based composites with high mechanical robustness and EMI shielding performance by a MXene/cellulose scaffold assembly strategy. The lignocellulose composites with a millimeter–thick mimic the “mortar-brick” layered structure, resulting in excellent mechanical properties that can achieve the compressive strength of 288 MPa and EMI shielding effectiveness of 39.3 dB. This “top-down” method provides an alternative for the efficient production of robust and sustainable EMI shielding materials that can be used in the fields of structural materials for next-generation communications and electronic devices.

Sustainable elastomers with high strength and unique functions are highly desired yet challenging. In this work, multiblock copolymer elastomers (MBCPEs) were synthesized by two sequential reversible addition–fragmentation chain transfer polymerization procedures with polytrithiocarbonate (PTTC) as the chain transfer agent and lignin-derived monomer vanillin acrylate as the rigid segment for the glassy blocks. Furthermore, magnetite (Fe3O4) microparticles were introduced into the as-prepared MBCPE to fabricate magnetic MBCPE@Fe3O4 composite elastomers. These composite elastomers exhibit significantly enhanced mechanical properties due to the excellent interfacial interaction between the microparticles and the matrix via the Schiff-base reaction. Besides, MBCPE@Fe3O4 composite elastomers show outstanding adhesion performance, magnetothermal behavior, and photothermal properties. Under near-infrared irradiation, the composite elastomers display rapid stimulus-healing and actuating phenomena via fast photothermal conversion. The combination of sustainable MBCPEs and functional microparticles can provide great potential for the development of intelligent materials with unique stimulus-responsive applications.

The phase-out of long chain per- and polyfluoroalkyl substances (PFAS) has accelerated the adoption of alternative emerging PFAS, posing a dual pollution challenge with persistent long-chain residues and their substitutes unclear fate in water treatment. Herein, we develop a scalable and closed-loop strategy producing aminated cellulose xerogel (CNPK) for PFAS removal. CNPK demonstrates excellent mechanical strength (1.96 MPa) and superior PFAS adsorption capacities (3.26 g g −1 HFPO-TrA, 1.82 g g −1 PFOA, 2.14 g g −1 HFPO-DA, 1.27 g g −1 PFHxA, 1.02 g g −1 PFBA and 1.01 g g −1 PFPrA) at pH 3. Its ability to absorb several times its own weight of PFAS is orders of magnitude higher than that of traditional adsorbents. In multi-component systems, the enhanced kinetics and affinity for short/ultra-short chain PFAS facilitate their near-complete removal. This is due to the preferential capture of long chains that provide additional van der Waals (vdW) interactions to accelerate short/ultra-chain adsorption. After five consecutive cycles, CNPK still achieves removal rates of 82%-99% for six types of PFAS and can be dissolved and reproduced. The proof-of-concept filter column achieves over 95% removal for short/ultra-short chain PFAS. The life cycle assessment (LCA) highlights xerogels having lower carbon footprint (161.28-161.71 kg CO 2 eq kg −1 PFAS) compared to most carbon-based adsorbents. Overall, this xerogel strategy tackles the urgent PFAS contamination through high-capacity enrichment under the principles of the circular economy.
