This study addresses the critical challenges of low ionic conductivity in polymer-based composite electrolytes for solid-state lithium batteries (SSLBs) arising from high interfacial impedance. A poly(ionic liquid) (PIL)-based composite electrolyte was engineered by modifying Li7La3Zr2O12 (LLZO) nanowire surfaces with pyridine-functionalized ionic liquid via electrostatic adsorption. This interfacial strategy constructs efficient Li+ transport pathways at the PIL/LLZO interface, significantly enhancing PIL chain segmental motion. The optimized electrolyte membrane achieves a high ionic conductivity of 2.79 × 10−4 S cm−1 at 25 °C. Symmetrical Li||Li cells demonstrate stable plating/stripping for 600 h, while the assembled LiFePO4||Li half cell delivers 169.81 mAh g−1 at 55 °C (0.5C rate) with 77.35 % capacity retention after 400 cycles, outperforming the unmodified system. This interfacial engineering approach provides a scalable strategy for developing high-performance SSLB electrolytes.

To boost electrochemical performance, fluorine-containing constituents are often introduced into lithium metal batteries (LMBs) to achieve superior properties. However, the underlying mechanism governing positional effects of fluorinated species remains unclear. Herein, three typical gel polymer electrolytes: fluorinated solvent-dominated (FSD), fluorinated polymer-dominated (FPD), and dual-site fluorinated-dominated (DFD) are systematically fabricated to investigate the related influence. Ionic conductivity, XPS characterization and molecular dynamics confirm the contribution of fluorinated solvent to the formation of stable and anion-derived inorganic-rich solid electrolyte interphase (SEI) layer. Density functional theory (DFT) results demonstrate that fluorinated polymer exhibits enhanced interaction energies, leading to increased free ion concentration. While Consistent conclusions can be drawn from diffusion coefficient analysis and distribution of relaxation times (DRT) results. By synergistically combining the merits of fluorinated solvents and fluorinated polymer, an ionic conductivity of 1.19 mS cm−1 is obtained for DFD and a minor polarization of 12 mV is achieved over 8000 h at 1 mA cm−1 in Li//Li battery. After assembling with LiFePO4, capacity retentions of 91.3 % and 91.6 % are maintained after 200 cycles at 1C under 25 °C and 60 °C, showing exceptional cycling stability, respectively, particularly under elevated-temperature operating conditions.
为了提高电化学性能，通常将含氟成分引入锂金属电池（lmb）中以获得优异的性能。然而，控制氟化物种位置效应的潜在机制仍不清楚。本文系统制备了三种典型的凝胶聚合物电解质：氟化溶剂主导（FSD）、氟化聚合物主导（FPD）和双位点氟化主导（DFD），以研究其相关影响。离子电导率、XPS表征和分子动力学证实了氟化溶剂对形成稳定的阴离子衍生的富无机固体电解质间相（SEI）层的贡献。密度泛函理论（DFT）结果表明，氟化聚合物表现出增强的相互作用能，导致自由离子浓度增加。而从扩散系数分析和弛豫时间（DRT）分布结果可以得出一致的结论。通过将氟化溶剂和氟化聚合物的优点协同结合，在Li//Li电池中，DFD的离子电导率为1.19 mS cm - 1，在1 mA cm - 1下，在8000 h内实现了12 mV的小极化。在与LiFePO4组装后，在25°C和60°C下进行200次循环后，其容量保留率分别保持在91.3%和91.6%，表现出优异的循环稳定性，特别是在高温操作条件下。

Phase change material (PCM) have several drawbacks, including liquid leakage, solid brittleness, low thermal conductivity and monofunctionality. In order to address these shortcomings, this study used polyurethane (PU) as the flexible packaging materials, palmitic acid (PA) as the phase change material, and h-BN as a thermal conductivity enhancer to create BN/PUPCM composite films with spatial network structure using prepolymerization crosslinking and physical mixing. The latent heat and thermal conductivity of the films can be efficiently enhanced by the PA and h-BN dispersed throughout the matrix structure. The composite film with R value of 1.5 and PCM content of 30 % has a good heat storage capacity, and its latent heat can reach 102.3 J/g. The BN/PUPCM@30 composite film exhibited a good mechanical performance, achieving a tensile strength of 12.0 MPa coupled with exceptional ductility (457.0 % elongation at break). The energy storage capacity of BN/PUPCM@30 remained constant even after 100 heating/cooling cycles, suggesting reversible energy storage capability and long-term thermal dependability. Furthermore, the BN/PUPCM@30 composite film displayed ultra-fast curing properties, achieving complete film formation within 4 min at 90 °C. Furthermore, introducing h-BN significantly improves the photothermal conversion and absorption of PUPCM, raising the temperature of the composite film by 4.9 °C, as can be seen from the infrared thermography. During the cooling process, an excellent temperature control capability was demonstrated by a constant temperature plateau lasting approximately 300 s. This work offers a novel method for creating polyurethane-based composite PCM with ultra-fast curing and thermal management capabilities.

High-temperature shape memory polymers (SMPs) often face inherent trade-offs between strain capacity and thermal stability. To address this challenge, we develop a novel shape memory polyimide (SMPI) that concurrently achieves record-breaking high temperature resistance and shape memory performance with a glass transition temperature (Tg) exceeding 230 °C, recoverable strain capabilities surpassing 450 %, and shape recovery higher than 99.5 %. This optimal performance balance stems from the synergistic interplay of molecular chain flexibility, dynamic hydrogen bonds, and covalent cross-linking networks. Molecular simulations and experimental analyses reveal the cooperative mechanisms between dynamic hydrogen bonds and covalent networks. Specifically, upon thermal activation, temperature-dependent dynamic hydrogen bonds dissociate, facilitating large-strain deformability. Conversely, upon cooling, their recombination restricts polymer chain mobility, enhancing shape fixity. Concurrently, the covalent cross-linking network suppresses plastic deformation during shape programming and accelerates shape recovery. Furthermore, we engineered polyimide fiber-reinforced SMPI composites that exhibited two-way shape memory behavior with 100 % cyclic retention over 10 cycles, demonstrating their potential to be applied in aerospace actuators and intelligent robots in extreme environments.

In this study, a multifunctional hybrid nanocomposite coating, designated as NanoTri-Shield, was developed to enhance both photocatalytic activity and long-term corrosion protection in saline environments. The innovation lies in the hierarchical integration of aminopropyltriethoxysilane (APTES)-functionalized Mo3C2Tx MXene (AMX) with CeO2-decorated mixed-ligand-etched ZIF nanocarriers (Ce@LZIF) and embedded zinc/phosphate (ZP) corrosion inhibitors within a unified protective system. The synthesis route employs a sequential sol–gel encapsulation and ligand-induced etching technique, enabling optimal dispersion and interfacial compatibility of nanofillers within the epoxy matrix. Photocatalytic tests showed 97 % degradation of methylene blue (MB) under UV and 80 % under visible light, driven by superoxide (O2•-) and hydroxyl (OH•) radicals, confirmed by ESR and radical scavenging studies. The electron transfer mechanism facilitated by MXene sheets significantly suppressed recombination, yielding superior photo-reactivity. Recyclability tests over five cycles revealed negligible loss in catalytic performance, confirming structural durability. Electrochemical impedance spectroscopy (EIS) and salt spray evaluations revealed outstanding anti-corrosion performance. After 90 days of immersion in 3.5 wt% NaCl, the intact E-ZP/Ce@LZIF/AMX coating retained an impedance modulus |Z|0.01Hz of 1.26 × 1010 Ω cm2. The E-ZP/Ce@LZIF/AMX coating showed self-healing index up to 1.947, Rt 126510 Ω cm2, and Rct 119310 Ω cm2, maintaining superior anti-corrosion performance over 72 h in 3.5 % NaCl. These findings highlight the promise of this hybrid system for photocatalyst and marine coating applications.

Silicon anodes have been extensively researched due to their high capacity and potential to revolutionize energy storage. However, during lithiation and delithiation cycles, the volume expansion of silicon anodes can lead to mechanical damage and significant capacity decay. To address this issue, three-dimensional polymer binders have been introduced to suppress volume changes by providing mechanical support. Although cross-linking in these binders improves their robustness, current options with high molecular weights and cross-linked structures are not biodegradable. To provide an environmentally friendly solution, we propose grafting degradable starch microspheres (DSM) with poly(acrylic acid) (PAA) and cross-linking with polyethylene glycol (PEG) to form DSM-g-PAA-c-PEG, a binder that demonstrates strong adhesive properties and superior mechanical strength compared to PAA. The UV–Visible spectrum confirms DSM's continued degradability. After cycling the Si@DSM-g-PAA-c-PEG anode 100 times at 0.25C, it achieves a capacity retention rate of 58.1 % with a reversible capacity of 2127.8 mAh g−1. This work provides new insight into the engineering of next-generation silicon electrode using an environmentally-friendly binding strategy, which may advance the large-scale industrial application of lithium-ion batteries.
硅阳极由于其高容量和革命性的能量存储潜力而受到广泛的研究。然而，在锂化和衰竭循环过程中，硅阳极的体积膨胀会导致机械损伤和显著的容量衰减。为了解决这个问题，三维聚合物粘合剂被引入，通过提供机械支撑来抑制体积变化。虽然这些粘合剂中的交联提高了它们的鲁棒性，但目前具有高分子量和交联结构的选择是不可生物降解的。为了提供一种环保的解决方案，我们提出将可降解淀粉微球（DSM）与聚丙烯酸（PAA）接枝，并与聚乙二醇（PEG）交联形成DSM-g-PAA-c-PEG，这种粘合剂与PAA相比具有很强的粘合性能和更高的机械强度。紫外可见光谱证实了DSM的持续可降解性。在0.25C下循环Si@DSM-g-PAA-c-PEG阳极100次后，其容量保持率为58.1%，可逆容量为2127.8 mAh g−1。本研究为下一代硅电极的环保结合提供了新的思路，有望推动锂离子电池的大规模工业应用。

Poly(3-hydroxybutyrate-co-4-hydroxybutyrate) (P34HB) is a biodegradable copolymer with considerable potential in biomedical and industrial applications. This study presents the first systematic metabolic engineering of Photobacterium sp. TLY01 for efficient production of P34HB. Multiple pathways for 4-hydroxybutyrate (4HB) monomer supply were engineered, including those utilizing γ-butyrolactone (GBL), 1,4-butanediol (BDO), and a de novo route from glycerol. Notably, Photobacterium sp. TLY01 demonstrated remarkable tolerance to GBL, and achieved up to 90 mol% 4HB incorporation via heterologous expression of the CoA transferase gene orfZ. The introduction of dhaT and aldD from Pseudomonas putida enabled 4HB synthesis from BDO. To establish a fully glycerol-based system, a succinate-derived 4HB pathway from Clostridium kluyveri was introduced, while three native gabD genes were deleted to redirect carbon flow toward 4HB formation, enabling P34HB production without exogenous precursors. Furthermore, deletion of gltA combined with supplementation of tricarboxylic acid cycle intermediates enhanced polymer biosynthesis, increasing P34HB titers by 3–4 times to approximately 15 g/L in shake-flasks. Fed-batch fermentation using the engineered strain TPS4O ΔgltA achieved a P34HB titer of 90.61 g/L with a yield of 0.44 g/g glycerol. These results establish a sustainable and scalable platform for P34HB production using a Vibrionaceae chassis.

Poly (phenylene oxide) (PPO), recognized for its exceptional dielectric properties, serves as a preferred matrix resin for high-frequency and high-speed copper-clad laminates (CCLs). However, research on functionalized PPO resins is constrained by synthesis challenges, relying primarily on two commercial resins with fixed molecular weights/distributions and insufficient end-group functionalization. These exhibit performance bottlenecks in higher-grade CCLs applications, and crucially, lack systematic studies on the structure-processing-property relationships governed by tunable precursor oligomer polymerization degrees (DP). This work employs precursor oligomer engineering via direct copolymerization with methacrylic anhydride (MMA) as the capping agent to synthesize a series of PPOn-MMA oligomers (DP, n = 5–25) featuring an ultrahigh difunctional group content (>97 %). These oligomers were blended with hydrocarbon resin, flame retardant, and crosslinker to prepare glass fiber-reinforced composites. Results demonstrate that the oligomer (DP, n = 5) significantly dictates processing behavior and performance: the system exhibits a minimum viscosity of 80 Pa⋅s (much lower than 700⋅Pa s for commercial resin), a 38.6 % increase in flexural strength, a glass transition temperature (Tg) elevated to 241 °C, and a 96.7 % increase in crosslinking density. The coefficient of thermal expansion (CTE) value is reduced to 8.6 ppm/°C (40–240 °C). Furthermore, it achieves an extremely low dielectric loss (Df = 0.0044) at 10 GHz with weak frequency dependence. This oligomer engineering strategy delivers superior processability, thermal resistance, mechanical strength, and dielectric properties. It elucidates the critical DP–processing–performance relationships, providing fundamental insights and technical pathways for developing high-performance functionalized low-molecular-weight PPO resins for next-generation high-frequency/high-speed CCLs.
聚（苯基氧化物）（PPO）以其优异的介电性能而闻名，是高频和高速覆铜层压板（ccl）的首选基体树脂。然而，功能化PPO树脂的研究受到合成挑战的限制，主要依赖于两种分子量/分布固定且端基功能化不足的商用树脂。这些在高档ccl应用中表现出性能瓶颈，而且至关重要的是，缺乏对可调前驱体低聚物聚合度（DP）控制的结构-加工-性能关系的系统研究。本研究采用前驱体工程技术，以甲基丙烯酸酐（MMA）为封盖剂，通过直接共聚，合成了一系列双官能团含量极高（> 97%）的PPOn-MMA低聚物（DP, n = 5-25）。将这些低聚物与碳氢树脂、阻燃剂和交联剂共混制备玻璃纤维增强复合材料。结果表明，低聚物（DP, n = 5）显著影响了加工行为和性能：体系的最小粘度为80 Pa·Pa·s（远低于商用树脂的700⋅Pa·s），弯曲强度提高38.6%，玻璃化转变温度（Tg）提高到241°C，交联密度提高96.7%。热膨胀系数（CTE）值降至8.6 ppm/℃（40 ~ 240℃）。此外，它在10 GHz时具有极低的介电损耗（Df = 0.0044），频率依赖性较弱。这种低聚物工程策略提供了卓越的可加工性、耐热性、机械强度和介电性能。它阐明了关键的dp -加工性能关系，为开发用于下一代高频/高速ccl的高性能功能化低分子量PPO树脂提供了基本见解和技术途径。

Flexible piezoresistive sensors are pivotal for next-generation wearable electronics, yet are fundamentally constrained by the sensitivity-range-stability trade-off inherent in conventional monoscale architectures. Herein, an efficient method that combines extrusion compression molding and sacrificial templating is proposed for the large-scale fabrication of the dual-microstructured thermoplastic elastomer (TPE)/carbon nanotubes (CNTs) sensor (MTCS). Through synergistic coordination between surface micropillar arrays and interface micropores, the MTCS achieves a 200 kPa detection range and sensitivity of up to 2.324 kPa−1. At the same time, the sensor exhibits minimal signal degradation following 2000 compression cycles and demonstrates a response time of 146 ms. The micropillar/micropore coordination enables dynamic reconstruction of conductive networks during compression. Micropore collapse enhances through-threshold conduction while micropillar deformation enlarges surface contact area. The MTCS achieves a balanced optimization of sensitivity, detection range, and stability while possessing the advantage of large-scale manufacturing, with performance sufficient to meet demands in scenarios like routine human motion monitoring. The proposed strategy offers a promising approach for advancing the development of flexible piezoresistive sensors.

Poly(propylene carbonate-co-phthalate) (PPC–P), limited by inferior melt strength and heat resistance, exhibits poor foamability and thermal stability. This study enhances PPC-P through biodegradable PLA incorporation and HDI-induced dynamic vulcanization of terminal hydroxyl groups, improving the interfacial compatibility. The gel contents, rheological properties, crystallization behaviours, mechanical properties, compatibility and microstructures of the PPC-P/PLA blends are investigated in detail. By adjusting the compatibilizer-NCO dosage and PLA contents, the melt strength and viscoelasticity of the blends are effectively enhanced and regulated. Enhanced interfacial compatibility among PPC-P and PLA phases, improves the tensile strength and elongation at break of PPC-P/PLA composites, with values of 48.2 MPa and 12.9 %, respectively. By using the sub-critical CO2 as blowing agent, light weight and low-shrinkage PPC-P/PLA foams with well refined cell structures are successfully obtained, which can be attributed to the improved melt strength and the induced thermal stability. The relationship between the crosslinked-crystalline network and the foam quality are established, including CO2 solubility, cell microstructure, and dimensional stability. PPC-P/PLA foams show refined microstructures (cell size <50 μm, cell density >1.5 × 109 cells/cm3, VER >20), and low shrinkage (<25 %). Here, the crosslinks and crystals play multiple essential roles in increasing the melt strength and foamability of PPC-P, providing a widely applicable low-shrinkage strategy, which is crucial for the biodegradable foams.
聚碳酸丙烯-邻苯二甲酸酯（PPC-P）由于熔体强度和耐热性较差，发泡性和热稳定性较差。本研究通过可生物降解的PLA掺入和hdi诱导的末端羟基动态硫化来增强PPC-P，改善界面相容性。详细研究了PPC-P/PLA共混物的凝胶含量、流变性能、结晶行为、力学性能、相容性和微观结构。通过调节增容剂nco的用量和PLA的含量，可以有效地提高和调节共混物的熔体强度和粘弹性。PPC-P与PLA相界面相容性增强，提高了PPC-P/PLA复合材料的抗拉强度和断裂伸长率，分别达到48.2 MPa和12.9%。使用亚临界CO2作为发泡剂，成功地获得了重量轻、收缩小、孔结构精细的PPC-P/PLA泡沫，这主要归功于熔体强度的提高和诱导热稳定性的提高。建立了交联结晶网络与泡沫质量的关系，包括CO2溶解度、孔微观结构和尺寸稳定性。PPC-P/PLA泡沫具有精细的微观结构（孔尺寸<；50 μm，孔密度>；1.5 × 109孔/cm3， VER >20）和低收缩率（< 25%）。在这里，交联和晶体在提高PPC-P的熔融强度和发泡性方面发挥了多种重要作用，为生物降解泡沫提供了广泛适用的低收缩策略，这对生物降解泡沫至关重要。
