Abstract Cellulose-based gel polymer electrolytes (GPEs) are promising sustainable candidates for next-generation lithium batteries; however, the relationship between polymer dynamics and ion transport remains insufficiently understood. In this study, cellulose-based GPEs with varying lithium salt concentrations and crosslinking densities were systematically investigated using broadband dielectric spectroscopy, complemented by structural and thermal characterizations. Three dielectric relaxations including a secondary $\beta$ relaxation, a structural $\alpha$ relaxation arising from cooperative segmental motion of the cellulose network, and a slower near-Debye ${\alpha }^{\prime }$ relaxation were identified.

Abstract Severe fluid loss in fractured formations remains a critical challenge in drilling operations, often leading to wellbore instability and increased non-productive time. Conventional plugging materials typically suffer from limited size adaptability and insufficient sealing efficiency under high-temperature conditions. To address these challenges, this study developed a plugging agent based on polystyrene microspheres (PSMs) via dispersion polymerization, using polyvinylpyrrolidone (PVP) as a dispersant. By tuning the molar ratio of PVP to styrene monomer, PSMs with controllable particle sizes (0.12–1.34 μm) were successfully synthesized. The results indicate that PSMs prepared at a PVP/SM molar ratio of 0.01, More >

Abstract Polyurethane (PU) adhesives are extensively used in wood bonding due to their high reactivity and strong adhesion. However, excessive penetration of the adhesive into the wood substrate often results in non-uniform bondline thickness, which can compromise joint performance. The use of environmentally compatible fillers offers a sustainable approach to address this limitation. In the present study, Tamarindus indica bark powder was used as a natural filler to achieve uniform bondline thickness in PU-bonded joints. Lap-shear joints were produced using untreated and treated bark powders at varying weight fractions, reinforced within a one-component moisture-curing PU adhesive. More >

Abstract 4D printing relies on smart materials capable of controlled deformation upon external stimuli. Existing photocurable shape memory polymers (SMPs) suffer from high viscosity, single (thermal) responsiveness, and insufficient deformability, which limit their applications. Herein, we report a low-viscosity, UV-curable SMP resin composed of tetrahydrofurfuryl acrylate, isobornyl acrylate, acryloylmorpholine as monomers and aromatic urethane dimethacrylate as crosslinker (TIA-AUD), with large deformability, tailor-made for digital light processing (DLP)-based 4D printing. We designed and synthesized a high-molecular-weight polyurethane based crosslinker with excellent properties. Through synergistic regulation of multiple reactive diluents to optimize resin performance, the material achieves outstanding… More >

Abstract Global freshwater scarcity has stimulated increasing interest in solar-driven interfacial evaporation for decentralized water purification. However, the development of low-cost evaporators that simultaneously achieve efficient photothermal conversion, continuous water supply, and functional separation of light harvesting and water transport remains a major challenge. Herein, we report a waste-cardboard-derived Janus cylindrical evaporator that integrates spatially separated photothermal conversion and water transport functions through a simple edge-immersion polydopamine (PDA) coating strategy followed by a rolling process. The PDA-coated upper region serves as a broad-band light absorber with a solar absorption exceeding 95% across 250–2500 nm and exhibits More >

Abstract High bio-based polymer foams face a critical challenge in balancing mechanical robustness with re-processability and environmental sustainability. In this work, a novel bio-based vitrimer foam was fabricated by integrating rigid rosin-derived Bis-glycidyl dehydroabietylamine epoxy resin (DGDHAA) with flexible epoxidized soybean oil (ESO) within a dynamic covalent network. Sodium bicarbonate served as the foaming agent, N,N-dimethylbenzylamine as the foam stabilizer, triethanolamine as the catalyst, and bis(3-aminopropyl) amine (BAPA) as both the curing agent and reactive diluent. The resulting DGDHAA/ESO-BAPA foams exhibited tunable glass transition temperatures (T_g) ranging from 95.88°C to 98.65°C with increasing BAPA content, along with More >

Abstract A novel plasticiser, Dioctyl Oligobutylene Terephthalate (DOOBT), was synthesised via esterification using p-Phthalic acid, 1,4-Butanediol, and 2-Ethyl-1-hexanol. Subsequently, polyvinyl chloride (PVC) films plasticised with DOOBT were prepared for characterisation. The chemical structure and properties of DOOBT and the resulting PVC films were analysed using Fourier Transform Infrared Spectroscopy (FT-IR), gel permeation chromatography (GPC), thermogravimetry (TG), Differential Scanning Calorimetry (DSC), scanning electron microscope (SEM) and a universal testing machine. The results showed that DOOBT is a polyester compound with an extremely low polymerisation degree. The glass transition temperature (T_g) of DOOBT-plasticized PVC products decreased significantly from 82.13°C… More >

Abstract Porous polymers are critical engineering materials whose internal voids endow them with low density, mechanical compliance, and large specific surface areas, making them indispensable for high-performance applications like tissue scaffolds, separation membranes, and energy-absorbing structures. However, conventional pore-forming strategies rely on stochastic mechanisms, failing to achieve continuous porosity gradients or customized geometries. While three-dimensional (3D) printing overcomes these limitations by encoding design-driven macropores, it remains fundamentally constrained by hardware resolution, making the fabrication of submicron features or hierarchical architectures challenging when used alone. To overcome these barriers, hybrid strategies combining 3D printing with physicochemical pore-forming More >

Abstract Benzoquinone-derived organic cathodes are gaining prominence in rechargeable lithium-ion batteries owing to their rapid redox kinetics and sustainable origins. However, their practical application is severely limited by the high solubility of benzoquinone species in organic electrolytes, which leads to rapid capacity decay during cycling. Although polymerization can effectively suppress dissolution, the resulting polymers often suffer from poor electronic conductivity and low utilization of redox-active sites. Herein, a p-phenylenediamine-benzoquinone polymer (PPD-BQ) was synthesized and integrated with reduced graphene oxide (RGO) to fabricate self-supported flexible composite films through a simple one-pot strategy. The uniformly distributed polymer layers effectively… More >

Abstract The selective recovery of lithium and uranium from seawater has attracted growing attention due to their strategic importance in energy storage (lithium) and nuclear power (uranium), as well as the vast yet underutilized marine reserves of these elements. However, their extraction remains highly challenging because of their ultra-low concentrations, the overwhelming abundance of competing ions, and the complexity of seawater chemistry. In this context, ion-imprinted polymers (IIPs) and ion-imprinted hydrogels (IIHs) have emerged as promising platforms owing to their target-specific recognition sites, tunable structures, and potential for selective adsorption in complex aqueous systems.

Abstract Ice accretion on aircraft airfoils poses a serious threat to flight safety by degrading aerodynamic performance and potentially causing premature stall. In airworthiness certification, dry-air flight tests with simulated ice shapes are required, and the structural strength of such artificial ice must be rigorously verified to prevent in-flight detachment. The study investigates both the aerodynamic impact of a typical glaze ice shape on a civil aircraft airfoil and the mechanical behavior of a designed simulated ice structure. Firstly, computational fluid dynamics (CFD) simulations using the k-ω SST turbulence model are conducted for climb/descent (0.2 Ma) and… More >

The findings revealed that the system demonstrated high operational adaptability and temporal responsiveness. The particles maintained robust suspension stability during injection, with >80 mesh particles sustaining up to a 98% suspension rate after 30 min at a… More >

Abstract To mitigate the environmental hazards of traditional petroleum thermosets and develop sustainable alternative materials, in this work, Dehydroabietylamine (DHAA), a renewable rosin derivative, was employed as the bio-based raw material to fabricate an environmentally benign vitrimer. Diglycidyl Dehydroabietylamine Epoxy Resin (DGDHAA) was first synthesized using DHAA and epichlorohydrin (ECH). The chemical structure of the synthesized DGDHAA was systematically characterized by FT-IR, ¹³C NMR, and ¹H NMR techniques. Subsequently, a bio-based vitrimer (denoted as DGDHAA/ESO-MNA) was prepared through the epoxy-anhydride curing reaction, with DGDHAA as the matrix, epoxidized soybean oil (ESO) as the toughening modifier, and methyl… More >

Abstract Gray mold disease induced by Botrytis cinerea is a devastating fungal infectionthat severely impairs the production of fruits and vegetables, especially strawberries. Conventional chemical fungicides not only cause severe environmental contamination but also readily induce fungicide resistance in Botrytis cinerea. Applying plant-derived natural antimicrobial agents, such as eugenol, as alternatives to chemical fungicides is a pivotal strategy for the development of green agriculture. However, ordinary eugenol emulsion biopesticides suffer from severe drawbacks, including easy leaching, rapid volatilization, and oxidation, which severely limits their effective control against Botrytis cinerea. In this study, an anionic waterborne polyurethane (PEOC-WPU) emulsion was… More >

Abstract The viscosity of polymer solutions often decreases significantly due to shear degradation in near-wellbore zones and chemical/aging degradation during long-term transport, which seriously compromises the efficiency of polymer flooding. In this study, a hydrophobic monomer, hexadecyl dimethyl-5-enhexyl ammonium bromide (HAB), was synthesized. Subsequently, a novel viscosity stabilizer (LC12) was prepared via micellar polymerization of acrylamide and HAB using sodium dodecyl sulfate (SDS) as a solubilizer. The effect of this stabilizer on a hydrophobic associating polymer (AP-P4) was evaluated. Experimental results revealed that the addition of LC12 accelerated the dissolution rate of the polymer concentrate and More >

Abstract Hepatitis has imposed a substantial burden on human health. Tumor necrosis factor-α (TNF-α) drives the inflammatory response by triggering downstream signaling, particularly the nuclear factor kappa B (NF-κB) pathway. Suppressing NF-κB activation represents a promising therapeutic strategy. PEGNB, a polymeric hydrogel, exhibits significant potential due to its superior cytocompatibility. We developed a controlled-delivery microgel platform by encapsulating Schisandra lignans (SLs) and mesenchymal stromal cells (MSCs) in polyethylene glycol-norbornene (PEGNB) microgels. To mimic an inflammatory hepatic microenvironment in vitro, Lipopolysaccharide (LPS)-induced HepG2 cells were encapsulated in bulk PEGNB hydrogel. The microgel–cell system enabled localized co-delivery of SLs… More >

In addition, oxidizing agents used in water treatment may threaten environmental and human health if they are not properly controlled. Hydrogen peroxide (H₂O₂) is one of the most widely used oxidants and therefore requires effective monitoring.
