This work presents the development of thin-film nanocomposite (TFN) nanofiltration membranes incorporating a Zn-based metal–organic framework/magnetic graphene oxide (ZnMOF@MGO) hybrid nanofiller to enhance the removal of toxic heavy metal ions from water. The ZnMOF@MGO particles were synthesized through a stepwise growth and magnetic integration process and characterized using FTIR, XRD, SEM, and VSM analyses, confirming successful hybrid formation and nanoscale crystallinity. These nanohybrids were dispersed within a polysulfone support and further integrated into the polyamide selective layer via interfacial polymerization to produce TFN membranes with filler loadings ranging from 0.1 to 0.5wt%. The membranes exhibited improved surface hydrophilicity (contact angle reduced from 69.54 to 48.55°), modified morphology, and enhanced structural tightness as evidenced by a decreased MWCO (700 Da for TFN0.2). Performance evaluation showed that the TFN0.2 membrane achieved the best overall separation efficiency, delivering a water flux of 116.3 L/m²·h along with high rejection of Pb²⁺ (99.14%), Hg²⁺ (82.18%), and As³⁺ (77.89%). Antifouling tests using BSA demonstrated a significant improvement in flux recovery (FRR = 98.55%) compared to the pristine TFC membrane. Although TFN0.5 exhibited slightly higher flux, excess nanofiller caused agglomeration and reduced selectivity. The results highlight the synergistic effects of ZnMOF@MGO nanohybrids in providing enhanced hydrophilicity, structural stability, permeability, and fouling resistance, confirming their strong potential for advanced nanofiltration applications in heavy-metal-contaminated water treatment.

本研究提出了一种薄膜纳米复合（TFN）纳滤膜的开发，该膜结合了锌基金属有机框架/磁性氧化石墨烯（ZnMOF@MGO）混合纳米填料，以增强水中有毒重金属离子的去除。通过逐步生长和磁集成工艺合成了ZnMOF@MGO颗粒，并通过FTIR， XRD， SEM和VSM分析进行了表征，证实了成功的杂化形成和纳米级结晶度。这些纳米杂化物被分散在聚砜载体中，并通过界面聚合进一步整合到聚酰胺选择层中，从而生产出填充量在0.1 - 0.5wt%之间的TFN膜。膜的表面亲水性得到改善（接触角从69.54°降低到48.55°），形貌得到改善，结构紧密性增强，MWCO降低（TFN0.2为700 Da）。性能评价表明，TFN0.2膜整体分离效率最高，水通量为116.3 L/m2·h，对Pb2+(99.14%)、Hg2+(82.18%)和As3+(77.89%)的去除率较高。与原始TFC膜相比，使用BSA进行的防污测试显示通量回收率有显著提高（FRR = 98.55%）。虽然TFN0.5的通量略高，但过量的纳米填料会导致团聚和选择性降低。研究结果强调了ZnMOF@MGO纳米杂化物在增强亲水性、结构稳定性、渗透性和抗污性方面的协同作用，证实了它们在重金属污染水处理中先进纳滤应用的强大潜力。图形抽象

Growing demand for sustainable composites has driven the exploration of natural materials hybridization. In this study, limitedly explored, Abutilon Indicum fiber was considered as epoxy reinforcement along with hemp. To investigate the effective proportion of Abutilon Indicum fiber in the epoxy composite, the samples were fabricated with balanced (AIHE-1) and unbalanced (AIHE-2 and AIHE-3) proportions of hemp and Abutilon Indicum through the compression moulding process and are compared over the Abutilon Indicum only inducted epoxy composite (AIE). The FTIR confirms the functional groups were consistent irrespective of the proportions of the reinforcements, indicating the stable interfacial bonding. The average crystalline size of the AIHE-1 was found to be 31.5 nm by XRD analysis. The better fiber distribution and interfacial bonding was found through SEM analysis for the AIHE-1. By that, AIHE-1 depicts higher thermal stability up to 374 °C, better sound absorption coefficient (average) of 0.20, and low surface roughness (average) of 55 nm as compared to AIE and unbalanced reinforcement composites. The wear analysis shows that the AIHE-1 has least wear rate of 0.12 mm³/N.m at the load of 30 N with the sliding speed of 2.25 m/s. These results suggest the balanced hybridization of Abutilon Indicum and hemp was recommended to use in interior automotive components for offering better thermal, acoustical, and wear properties.

对可持续复合材料日益增长的需求推动了对天然材料杂交的探索。在本研究中，有限的探索，阿布蒂隆Indicum纤维被认为是环氧树脂增强与大麻。为了研究Abutilon Indicum纤维在环氧复合材料中的有效比例，通过压缩成型工艺制备了大麻和Abutilon Indicum的平衡（AIHE-1）和不平衡（AIHE-2和AIHE-3）比例的样品，并与Abutilon Indicum仅诱导的环氧复合材料（AIE）进行了比较。FTIR证实，无论增强剂的比例如何，官能团都是一致的，表明界面键合稳定。通过XRD分析发现AIHE-1的平均晶粒尺寸为31.5 nm。通过SEM分析发现AIHE-1具有较好的纤维分布和界面结合。因此，与AIE和非平衡增强复合材料相比，AIHE-1具有高达374°C的更高热稳定性，更好的吸声系数（平均）为0.20，表面粗糙度（平均）为55 nm。磨损分析表明，AIHE-1的最小磨损率为0.12 mm3/N。在30 N载荷下，滑动速度为2.25 m/s。这些结果表明，为了提供更好的热、声学和磨损性能，建议将Abutilon Indicum和hemp的平衡杂交用于汽车内饰件。图形抽象

The development of environmentally friendly packaging materials is a globally significant issue due to the environmental problems caused by high production, excessive use, and improper disposal of synthetic plastics. Therefore, this study focuses on developing films based on natural polymers, such as starch and chitosan, and assessing the effects of adding different triblock copolymers on their physicochemical properties. The films were developed using the casting method, and their thermal, water adsorption, and wettability properties, as well as their biodegradability in water and compost, were examined at the laboratory level. Translucent, manageable films were obtained, with a thickness range of 53 to 127 μm. The results indicate that all formulated films display a mainly hydrophilic nature, with contact angles between 18° and 44°, and a swelling index from 49% to 65%. Films with triblock copolymers of molecular weight less than 3000 g/mol showed a lower water vapor absorption capacity (19%) under high relative humidity conditions (90%). According to FTIR and XRD analyses, using different triblock copolymers prevented starch retrogradation. However, they did not negatively impact the biodegradation process of these materials, as biodegradation in liquid water ranged from 36% to 40%, and reached 100% in compost at the laboratory level at 70 days. The study results show that adding different triblock copolymers or Pluronics to the starch/chitosan matrix enhances the functional properties of the films without impacting the biodegradation process. Therefore, incorporating uncommon additives like triblock copolymers into packaging material formulations is a feasible option for creating new materials.

由于合成塑料的高产量、过度使用和处置不当造成的环境问题，开发环保包装材料是一个全球性的重大问题。因此，本研究的重点是基于淀粉和壳聚糖等天然聚合物开发薄膜，并评估添加不同三嵌段共聚物对其物理化学性能的影响。采用浇铸法制备薄膜，并在实验室水平上测试了其热性能、吸水性、润湿性以及在水和堆肥中的生物降解性。获得了厚度为53 ~ 127 μm的半透明可控薄膜。结果表明：所配制的膜以亲水性为主，接触角在18°~ 44°之间，膨胀指数在49% ~ 65%之间。分子量小于3000 g/mol的三嵌段共聚物薄膜在高相对湿度条件下（90%）的水蒸气吸收量较低（19%）。FTIR和XRD分析表明，使用不同的三嵌段共聚物可以防止淀粉的降解。然而，它们并没有对这些材料的生物降解过程产生负面影响，因为在液态水中的生物降解率从36%到40%不等，在70天的实验室水平上，堆肥的生物降解率达到100%。研究结果表明，在淀粉/壳聚糖基质中添加不同的三嵌段共聚物或Pluronics可提高膜的功能性能，而不影响生物降解过程。因此，在包装材料配方中加入不常见的添加剂，如三嵌段共聚物，是创造新材料的可行选择。图形抽象

Composites are materials with high specific strengths. These materials can be examined in terms of mechanical strength by experimental or finite element methods (FEM). It has been determined in the literature that various material models are used in modeling composite materials by finite element method. In order to model composite materials correctly by FEM, it is very important to determine the material model data (physical and non-physical parameters) correctly. However, there are limited studies in the literature on determining the physical and non-physical parameters used for Ls dyna software material models of materials. For this reason, the material model data of unidirectional glass/epoxy composite material in different temperature environments were determined by FEM (Ls dyna software and MAT 55/MAT 59 material models) in the study. Material model data were determined by comparing the experimental results of composite materials with the results obtained by the FEM. As a result of the study, both material model data were obtained and the effect of the thermal environment on the material model data was investigated. It was determined that the material model data also changed with the change of ambient temperatures. Moreover, it was determined that the MAT 59 material model gave better results.

This study selected poly (1, 4-cyclohexanedimethanol isosorbide terephthalate-co-ethylene terephthalate), whose abbreviation is PCIC, as the matrix and mainly explored the influence of antioxidant types and addition amounts on the optical properties of PC_30%IC. Through comprehensive characterization methods such as Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and transmittance testing, the structure, morphology, thermal and optical properties of the synthesized composites were investigated. It was found that triphenyl phosphite (TPPi) had a better color protection effect on ISB. The performance of PC_30%IC with different TPPi addition ratios was studied. The results showed that TPPi itself did not participate in the reaction, so there were no obviously characteristic peaks in the infrared and nuclear magnetic resonance test results of the product. However, TPPi could appropriately increase the molecular weight of the copolymer, and the T_g and tensile properties of the copolymer also got a slight improvement. TGA curves showed that TPPi had little effect on the Td_5% of the copolymer, but its Td_max has been increased. Moreover, the addition of TPPi could inhibit the cross-linking reaction or carbonization which could aslo reduce the residual mass. More importantly, TPPi could prevent the occurrence of oxidation reactions by capturing free radicals and decomposing peroxides, thereby reducing the formation of chromophores. However, this effect was limited. When the addition amount of TPPi reached 0.005 of the total molar mass of the alcohol, phase separation occurred, which instead reduced the transmittance. When the content of TPPi was 0.003, the ultraviolet transmittance of the film was the best, reaching 90.94%, with a b* value of 1.25.

本研究选择聚（1,4 -环己二甲醇异山林酯对苯二甲酸乙二醇酯-共乙烯对苯二甲酸乙二醇酯）（简称PCIC）为基体，主要探讨了抗氧化剂类型和添加量对PC30%IC光学性能的影响。通过傅里叶变换红外光谱（FTIR）、扫描电镜（SEM）、热重分析（TGA）、差示扫描量热法（DSC）、透射率测试等综合表征方法，对合成的复合材料的结构、形貌、热学和光学性能进行了研究。结果表明，亚磷酸三苯酯（TPPi）对ISB有较好的护色效果。研究了不同TPPi添加比例下PC30%IC的性能。结果表明，TPPi本身没有参与反应，因此在产物的红外和核磁共振检测结果中没有明显的特征峰。然而，TPPi可以适当增加共聚物的分子量，共聚物的Tg和拉伸性能也得到了轻微的改善。TGA曲线显示，TPPi对共聚物的Td5%影响不大，但其Tdmax有所提高。此外，TPPi的加入可以抑制交联反应或炭化反应，也可以降低残余质量。更重要的是，TPPi可以通过捕获自由基和分解过氧化物来阻止氧化反应的发生，从而减少发色团的形成。然而，这种效果是有限的。当TPPi的加入量达到醇总摩尔质量的0.005时，发生相分离，反而降低了透光率。当TPPi含量为0.003时，薄膜的紫外线透过率最佳，达到90.94%，b*值为1.25。图形抽象

Nanocomposite polymer electrolytes (NCPEs) have emerged as a key class of materials for next-generation energy storage systems, offering a unique balance of ionic conductivity, mechanical integrity, and thermal stability. This review critically examines three major fabrication approaches electrospinning, sol–gel processing, and organic–inorganic hybrid strategies highlighting their underlying principles, advantages, and limitations. Electrospinning-derived NCPEs demonstrate high ionic conductivity and flexibility, making them attractive for wearable and flexible devices, but their scalability remains limited. Sol–gel derived NCPEs exhibit superior thermal stability and uniform nanoparticle dispersion, positioning them as promising candidates for solid-state lithium batteries, though their cost and time-intensive processing hinder commercialization. Hybrid NCPEs integrate the strengths of both approaches, achieving multifunctional properties with balanced performance, yet face challenges related to interfacial compatibility and filler supply chains. Advanced characterization methods including scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV), linear sweep voltammetry (LSV) and galvanostatic charge–discharge (GCD) are discussed, along with the emerging role of in situ and operando techniques in revealing dynamic processes. Future directions emphasize the design of self-healing and stretchable NCPEs for flexible energy storage, bio-based electrolytes for sustainability, and the integration of artificial intelligence to accelerate materials discovery and predictive modeling.

This review critically examines three major fabrication approaches electrospinning, sol–gel processing, and organic–inorganic hybrid strategies highlighting their underlying principles, advantages, and limitations. Electrospinning-derived NCPEs demonstrate high ionic conductivity and flexibility, making them attractive for wearable and flexible devices, but their scalability remains limited. Sol–gel derived NCPEs exhibit superior thermal stability and uniform nanoparticle dispersion, positioning them as promising candidates for solid-state lithium batteries, though their cost and time-intensive processing hinder commercialization.

The increase in fatal diseases associated with microbial activity is posing a great threat worldwide. Numerous techniques are being developed to inhibit the activity or kill the microbes using bioactive materials based on naturally available resources. The current study presents a novel green approach for the synthesis of polymeric membranes based on whole maize grain and p-coumaric acid [poly(p-CA)-cl-M^g-membrane], using a solvent casting method and radical-copolymerization. The prepared membrane was characterized using various techniques including mechanical, antimicrobial, and biomedical properties, showcasing remarkable versatility. The membrane exhibited mechanical flexibility (stiffness: 0.117 N/mm, elongation-at-break: 20%, thickness: 404 μm) and demonstrated impermeability to microbial penetration, high oxygen permeability, and potent antioxidant activity (76.77% radical scavenging). Antimicrobial tests revealed significant inhibition zones against pathogens commonly associated with skin infections, including Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, and Shigella flexneri. Furthermore, the membrane was evaluated as a topical drug delivery system using iodine as a model drug. Drug release studies confirmed a sustained release profile (95.89%) following zero-order kinetics at pH 7.4 over 450 min. The combination of efficient gas exchange, antioxidant protection, and antimicrobial performance highlights the potential of [poly(p-CA)-cl-M^g-membrane] for advanced biomedical applications, including wound care and controlled drug delivery systems.

The present research aims to develop eco-friendly green composites using cashew nutshell liquid (CNSL) as a bio-based resin and natural fibres such as manga bamboo, areca nut palm leaf sheath, and coconut leaf midrib as reinforcements. To enhance mechanical integrity, fracture resistance, and load transfer efficiency, graphene, single-walled carbon nanotubes (CNTs), and silicon dioxide nanoparticles were incorporated in selected weight ratios. Prior to composite fabrication, fibres were treated with silane and alkali solutions to improve interfacial bonding. A total of eighty-one composite samples were produced using compression moulding, vacuum bagging, and hand lay-up techniques, with twenty-seven specimens prepared by each method. A Taguchi L81 orthogonal array was used to evaluate the combined influence of five factors i.e., manufacturing process, nano-filler type, fibre treatment, fibre type, and fibre weight%, each at three levels. The mechanical and water absorption characteristics of the developed composites were analyzed, and scanning electron microscopy was used to study fibre-matrix adhesion, filler dispersion, and fracture behaviour. The optimization study revealed that compression moulding, 10% (by wt) bamboo fibre, graphene nano-filler, and silane surface treatment provided the most desirable combination, achieving a tensile strength of 39.6 MPa, flexural strength of 32.5 MPa, and water absorption of 12.9%. The enriched mechanical properties and reduced moisture uptake confirm the potential of CNSL-based green composites as a sustainable and lightweight material suitable for future structural and engineering applications.

In Filament Winding (FW) techniques, uninterrupted fiber tows are deposited onto a rotating mandrel for closed cylindrical structures. It is the most frequently used process for the fabrication of pipes, tubes, shafts, and pressure vessels. This also allows high cable placement precision, high percent fiber content, and low material wastage. To use the maximum strength of fibers, reinforcement is given uniformly in the FW directions. Proper design and winding technique would involve maximum fiber strength in the winding direction chosen. The present review connects 50 research papers published from 2015 to 2025 that relate to filament-wound polymer composite cylindrical tubes, thus providing an organized review of current knowledge and findings. It summarizes materials selection, fiber type, matrix system, and parameters of production with their influence on tensile strength, flexural strength, and impact resistance. The mechanical properties were derived from the experimentally validated results reported in the literature reviewed by applying standard test methods such as ASTM tensile tests, low-velocity impact tests, and Finite Element (FE) modeling. The review states that the control of fiber orientation with advanced methods of reinforcement is one major contributor to structural integrity. It further throws some light on how manufacturing parameters like winding patterns, winding load, and curing conditions influence final properties. It also highlights the diverse applications of filament-wound polymer composite cylindrical tubes in different industries. Finally, the paper highlights the gaps in the existing research and outlines directions for future research.

3D printed novel bio-inspired auxetic metamaterial structure with tunable geometry for improved light weight cutting tool stiffness and energy absorption 3D打印新型仿生辅助超材料结构，具有可调几何形状，可改善轻质刀具刚度和能量吸收

This paper investigates the compression behavior of a novel circular bio-inspired auxetic metamaterial, characterized by hourglass-shaped gaps in its unit cells, unlike typical re-entrant or chiral designs that use straight ribs or spirals. The achieved exceptional auxetic behavior was a result of the unique cell geometry, inspired by the structure of a spider’s body. A 3D-printed specimen with an x-angle of 140° was subjected to compression testing, demonstrating a negative Poisson’s ratio where the structure contracts laterally under axial loading. The load–displacement curve exhibited three distinct regions, linear, decreasing slope, and steady state, with the simulation closely matching experimental results, differing by only 10% in stiffness and 0.3% in peak load. Stress and strain analyses revealed the formation of localized high-stress regions and gradual softening during deformation. The influence of x-angle on performance was also investigated, showing that increasing the x-angle enhanced both maximum load and energy absorption. Stiffness increased from 405 N/mm at 120° to 854.5 N/mm at 160°, while energy absorption improved by 68.5%. Furthermore, normalized stiffness and specific energy absorption (SEA) were evaluated, both exhibiting a positive correlation with x-angle. The SEA–strain curves followed an S-shaped trend, indicating progressive energy absorption with increasing deformation. These findings highlight the tunable mechanical characteristics of the proposed design, demonstrating its potential for lightweight, high-performance applications such as vibration-damping and stiffness-optimized cutting tools.
