Flexible transparent conductive films based on copper nanowires (Cu NWs) are used in a variety of optoelectronic devices. However, their use is limited due to poor stability and adhesion. Herein, highly reliable flexible transparent conductive thin films consisting of SrSnO 3 (STO) and Cu NWs are fabricated using a combination of spin-coating and radio frequency magnetron sputtering techniques. The optical and electrical properties can be modified by changing the number of spin-coating cycle of Cu NWs. The STO thin films can effectively improve optical–electric performance of Cu NWs (before coating STO: 22.1 Ω/sq. at 81.5%, after coating STO: 18.7 Ω/sq. at 82.8%). Furthermore, after 20 tape tests and 2000 bending cycles (with a bending radius of 5.0 mm), the resistance of STO/Cu NW composites remains unchanged, demonstrating exceptional mechanical flexibility and adhesion retention. In addition, the composites show higher stability to high-temperature and high-humidity conditions, oxidation, corrosion, and sulfidation compared with that of Cu NW networks, which is due to the effective covering of STO layer. The combination of these characteristics makes the composite thin films an excellent candidate for substrates of novel flexible optoelectronic devices.

The development of conductive greases with friction-reducing, anti-wear, and anti-electrical corrosion performance provides an effective solution to mitigate bearing electrical erosion in electrical vehicles. In this study, a titanium carbide MXene (Ti 3 C 2 T x )-based eutectic hydrogen-bonded thickener is successfully synthesized through micro-interface reactions by exploiting the different reaction rates of –NH 3 , H 2 O, and –CNO functional groups. Tribological experiments indicate that the hydrogen bonding within the Ti 3 C 2 T x -based eutectic thickener facilitates the co-release of the thickener and Ti 3 C 2 T x nanosheets at tribological interfaces, thereby enhancing the lubricating film thickness. Moreover, the M-0.5 system (Ti 3 C 2 T x concentration of 0.5 wt%) achieves a 91 % reduction in wear volume, significantly decreases contact resistance, and effectively mitigates electrical corrosion. This study presents a feasible strategy for the design of two-dimensional oil-soluble complexes for the protection of grease lubricated bearings.

High-capacity silicon/carbon composite anodes for lithium-ion batteries face rapid capacity degradation from extreme volume changes due to conventional organic-dominated solid electrolyte interphase (SEI) lacking mechanical/ionic stability. Constructing robust inorganic SEI (e.g., LiF-dominated interphases) requires synergistic control of electrolyte interactions at the inner Helmholtz plane (IHP) and stress-adaptive interfacial architectures. Herein, a hierarchical dual-coating strategy integrating polyaniline (PANi) and laser-induced graphene (LIG) on SiO x anodes addresses this challenge. PANi layer selectively enriches fluorinated ethylene carbonate (FEC) at the IHP via dipole-dipole interaction, enabling preferential FEC reduction at 1.3 V (vs. Li/Li + ) to form LiF-dominated SEI. Theoretical calculations confirm higher FEC adsorption density and stronger adsorption energy on the hierarchically dual-coated SiO x /LIG/PANi-2 (−0.33 eV) versus bare SiO x (−0.09 eV). Meanwhile, LIGʼs 3D porous conductive scaffold dissipates stress, sustaining structural integrity under repeated expansion. The optimized SiO x /LIG/PANi-2 anode achieves 1812.5 mAh g −1 initial capacity with 90.5 % initial Coulombic efficiency at 0.1 A g −1 and retains 87.7 % capacity after 1000 cycles at 2.0 A g −1 , demonstrating exceptional electrochemical stability. Post-cycling analyses further validate the homogeneity of LiF-rich SEI, robust mechanical resilience, and exceptional electrode integrity. This atomic-scale IHP regulation, harmonized with macro-scale stress engineering, offers scalable strategies for silicon anodes in high-energy-density batteries.

Superhydrophobic coatings exhibit significant potential for various applications, but their practical application is hindered by poor durability. Achieving high durability often relies on fluorinated reagents, posing environmental pollution risks. Herein, a fluorine-free strategy for fabricating durable and environmentally friendly superhydrophobic coatings was proposed to address these challenges. Octadecylamine-functionalized graphene oxide (ODA-GO) without fluorine compounds was synthesized via microwave-assisted ball milling. Subsequently, a superhydrophobic coating was established by spraying a mixture of ODA-GO, epoxy resin, and polydimethylsiloxane. The resulting coating demonstrated high superhydrophobicity, with a water contact angle greater than 161° on various substrates, and outstanding durability. After immersion in chemical solvents (NaCl, HCl, NaOH) for 24 h, prolonged ultraviolet (UV) irradiation, high-temperature exposure, and a series of mechanical stability tests, including tape peeling, sandpaper abrasion, sand impact, and water impact, the coating consistently maintained its superhydrophobic properties. Furthermore, the coating achieved a polarization resistance of 1.76 × 10 6 Ω·cm 2 after 21 days in a 3.5 wt% NaCl solution and maintained a high oil-water separation efficiency of up to 98 %. This work provides a green, fluorine-free approach for highly durable superhydrophobic coatings, paving a potential path for their practical applications in marine anti-corrosion and protective coatings for industrial equipment.

The treatment of posterior uveitis remains challenging due to the need for long-term medication and the limited efficacy of current therapies. In this study, we developed an injectable rapamycin-based nanoparticle formulation designed to extend intraocular residence time and enhance retinal penetration, thereby improving therapeutic outcomes. The nanoparticles were formed via self-assembly of rapamycin conjugated with a hydrophobic alkyl chain, yielding uniformly spherical particles with an average diameter of approximately 90 nm. In vitro experiments confirmed that the formulation exhibited minimal cytotoxicity, potent anti-inflammatory effects, inhibition of endothelial cell migration, and efficient uptake by retinal pigment epithelial (RPE) cells. In vivo imaging demonstrated that the nanoparticles rapidly localized to the RPE layer of the posterior segment following intravitreal injection, in contrast to the free drug. Moreover, experimental autoimmune uveoretinitis (EAU) rats treated with nanoparticles exhibited a substantial alleviation of ocular inflammation and a concomitant reduction in the expression of inflammatory markers, including CD45, CD68, IBA-1, and IL-17.

Rheumatoid arthritis (RA), a chronic autoimmune disorder affecting 1% globally, urgently demands advanced therapies to overcome the systemic toxicity and limited efficacy of conventional glucocorticoids like dexamethasone (Dex). In this study, we constructed LMWH-Gly-Pro-ODA/Dex (LGPO/Dex) micelles, which synergistically integrate low molecular weight heparin (LMWH)-mediated active targeting with Gly-Pro-mediated fibroblast-activated protein (FAP)-α-responsive drug release to achieve spatiotemporal precision in RA treatment. The system operates through a three-stage cascade mechanism: (1) targeting the inflamed joints, (2) inflammation-responsive drug release to modulate pathological microenvironments (e.g., normalizing M1/M2 macrophage polarization), and (3) suppression of monocyte recruitment to prevent disease progression. LGPO/Dex micelles showed excellent RA therapeutic effects in the adjuvant-induced arthritis (AIA) model. Joint swelling, serum TNF-α, and nitric oxide (NO) levels in LGPO/Dex-treated rats showed no significant difference from healthy controls (ns) while exhibiting marked improvement over Dex monotherapy (**, P < 0.01). Notably, it also significantly reduced Dex-associated adverse effects. This study confirmed the feasibility of using FAP-α as a therapeutic target for RA and provided a new idea for RA treatment, offering a blueprint for disease-microenvironment-programmed therapeutics.

Inflammatory infiltration and inappropriate friction remain the two main challenges in treating osteoarthritis (OA). An effective treatment platform is anticipated to lubricate the cartilage and ameliorate intra-articular inflammation. Herein, injectable hydrogel microspheres with chondroitin sulfate (Chs)/sericin methacryloyl (SerMA) designed as the core and grafted with folic acid (FA)- and 78c-modified liposomes (78c@Lipo-FA) by DSPE-PEG2k-GPLGLAGQC (DPG) peptides, namely LFDCS, was formed by thin-film hydration and microfluidic methods. Physically, LFDCS exhibited cartilage lubrication and adhesion capability as the bionic bearings. Meanwhile, with the degradation of LFDCS, Chs were set out to promote chondrocyte function. Physiologically, 78c@Lipo-FA were released from LFDCS enzymatically responsible to matrix metalloprotein-9 (MMP9) due to the split of DPG motif, which specifically bound to classical-activated macrophages (M1) by ligating to FA receptor through FA and inhibit M1 function by 78c, consequently rescued cartilage from degradation by inflammation. Mechanically, an RNA sequencing analysis revealed that the LFDCS could ameliorate chondrocyte dysfunction by down-regulating PI3K/AKT signaling and inflammation response. LFDCS greatly reduced friction on articular surfaces, suppressed M1-induced inflammation and attenuated chondrocyte dysfunction in OA rats. In conclusion, the bionic bearing-inspired lubricating microspheres characterized by M1-phenotype macrophage-targeted addresses the unfavorable factors of both the physical and physiological microenvironments in macrophage-mediated diseases.

The development of novel pesticide formulations with the minimization of the adverse impact and simultaneous maximization of utilization efficiency is highly urgent. A new window for pesticide delivery has been created for green and sustainable agriculture using chitosan (CS) and chitooligosaccharide (COS) as carrier materials because of their economic, biocompatibility, and versatile functional properties. However, the difference of properties between CS and COS is not well clarified in pesticide delivery. In this study, pyraclostrobin (PYR)-loaded microcapsules based on arginine-modified CS (PYR@CS-Arg) or COS (PYR@COS-Arg) were successfully prepared through an electrostatic self-assembly strategy. Notably, in addition to possessing pH-responsive release characteristics, PYR@CS-Arg exhibited faster release kinetics in alkaline environments compared to PYR@COS-Arg, attributed to the formation of a larger space following CS-Arg dissociation from microcapsules. Comparative analysis with other formulations revealed that both PYR@CS-Arg and PYR@COS-Arg demonstrated superior performance in terms of target deposition, bioactivity, UV stability, biosafety, and nutritional function. These characteristics significantly enhance the pesticide utilization rate while reducing environmental risks, aligning with the principles of sustainable agricultural development. Owing to the multifunctional properties of COS, PYR@COS-Arg showed enhanced performance in maximum retention, fungicidal activity, UV protection, and plant growth promotion compared to PYR@CS-Arg. Conversely, PYR@CS-Arg exhibited lower nontarget organism acute toxicity, owing to its larger particle size facilitating gravitational sedimentation in aqueous environments. These findings provide valuable insights into carrier material selection based on application scenarios and target control requirements, offering a promising and practical strategy in sustainable agricultural practices.

This study aims to reduce dependence on copper while enhancing the energy density of lithium-ion batteries. Plastic-based current collectors (PBCCs) offer a promising approach to replace copper, minimize the proportion of inactive material, and ultimately increase the energy density of lithium-ion batteries. A key challenge involved the synergistic optimization of the PBCC's conductive framework and its interfacial surface properties. Herein, a PI-CNT-Cu composite membrane was constructed by depositing copper onto electrospun PI fibers containing CNTs. This hierarchical architecture coupled the intrinsic longitudinal conductivity of the CNT network within the fibers with the transverse conductivity of the continuous copper layer, resulting in a composite membrane with a volumetric conductivity of 5.6 × 103 S cm−1. In the electrochemical performance evaluations, graphite anodes employing PI-CNT-Cu CCs exhibited a capacity retention of 95.29% after 190 cycles at 0.5C. The performance enhancement could be attributed to the markedly rougher surface of the PI-CNT-Cu CC (Sa = 2.668 µm) relative to copper foil (Sa = 0.938 µm). This morphology enhanced the contact area and adhesion with the electrode layer, which was crucial for maintaining the structural integrity of the electrode during long-term cycling. In contrast to copper foil, the PI-CNT-Cu CC, with its fiber-woven structure, exhibited a significantly lower areal density with identical thickness values. The capacity of the anode electrode, was calculated based on the total mass including active materials and CCs. Utilizing PI-17%CNT-Cu exhibited significantly higher discharge capacities of 81.7 mA h g−1 at the same rates compared to the Cu foil at 35.08 mA h g−1.

This study aims to develop high-performance polymer nanocomposites based on perfluoroelastomers (FFKM) using an integrated framework that combines molecular dynamics (MD) simulations, machine learning (ML), and experiments to investigate the factors governing tribological behavior. The friction coefficient shows negative correlations with temperature, normal load, and sliding velocity. Increasing the sliding velocity raises the average diffusion coefficient from 0.00422 to 0.04300. Increasing the normal load increases the transfer film thickness by 39.13% and reduces surface roughness by 36.19%. The SDM model achieves the highest prediction accuracy (R 2 = 0.9662), outperforming conventional algorithms. Among six friction test conditions, the minimum friction coefficient is 1.339. Two conditions with identical PV values of 0.1 exhibit similar friction coefficients (1.604 and 1.646). The experimental trends are consistent with the MD and ML results. Highlights A comprehensive research framework of MD simulation, ML, and experiments. The COF of FFKM is negatively correlated with multiple factors. A novel ensemble algorithm, SDM, is developed for friction prediction. Experimental results show clear and consistent trend indications.

Meta aromatic polyamide (PMIA) has high rigidity and low flexibility due to the rigid molecular structure and highly oriented hydrogen bonding interactions, which will make the stress concentration and damage of PMIA by force. It is necessary to improve flexibility while maintaining mechanical strength. The influence of different aromatic ether structure on properties of PMIA and the evolution mechanism of molecular chain conformation in flexible PMIA fibers during the drawing process are not clear. This work obtained two flexible PMIA fibers (PMAB-PMIA and ODA-PMIA) by introducing 1,3-bis (4-aminophenoxy) benzene (PMAB) and 4,4′-diaminodiphenyl ether (ODA) into molecular chain. The properties of PMIA with different aromatic ether structures and microscale analysis during drawing were explored. The flexible PMIA maintained excellent mechanical properties, thermal stability, and flame retardancy. The tensile strength of pristine PMIA, PMAB-PMIA and ODA-PMIA was 2.68, 2.55 and 2.64 cN/dtex, respectively, meaning that flexible PMIA fibers kept high tensile strength. Compared with pristine PMIA, the elongation at break of PMAB-PMIA and ODA-PMIA increased by 30.1 % and 16.4 %. Their maximum number of twists also increased from 177 to 237 and 258 twists/10 cm. The increased elongation at break and torsional resistance proved that flexibility of modified PMIA elevated. The molecular dynamics (MD) simulations indicated that the molecular chains of aromatic-ether PMIA had more folded conformations, thus offering superior flexibility and stress dissipation capabilities at microstructural level. This work systematically explored high-strength and flexible PMIA fibers based on aromatic ether, which is expected to guide the material design of future functional fibers.

In this study, glass fiber/polyimide composite aerogel (GF/CLPI) was successfully fabricated via directional freezing technology. By precisely controlling the mass ratio of polyamic acid salt to glass fiber (GF) powder (ranging from 5:1 to 1:2), and through high-speed blending, liquid nitrogen-induced directional crystallization, freeze-drying, and stepwise thermal imidization processes, anisotropic structured materials were obtained. Microscopic characterization revealed that the axial cross-section exhibited a honeycomb-like interconnected pore structure. At the same time, the radial direction formed a layered orientation. GF were uniformly embedded in the polyimide pore walls, resulting in a homogeneously distributed reinforcing phase. Performance tests demonstrated that the material had an initial decomposition temperature of 490 °C in air and 550 °C in nitrogen. Furthermore, the radial thermal insulation performance (thermal conductivity ranging from 27.4 to 36.6 mW·m −1 ·K −1 ) was significantly superior to that in the axial direction (thermal conductivity ranging from 27.5 to mW·m −1 ·K −1 ). At elevated temperatures, the polyimide matrix and GF cooperatively formed an insulating carbonized layer, thereby endowing the material with self-extinguishing properties. This structure-property coordinated regulation strategy offers a novel approach for the development of advanced lightweight thermal insulation materials.
