Hydrogen is vital to sustainable energy systems, yet developing efficient and cost-effective gas barrier materials for hydrogen storage remains a challenge. This study investigates the hydrogen barrier performance of 3D-printed nanocomposites based on Polyamide-12 (PA12) filled with 0–2 wt% of few layer formulated graphene inks (PAG). A unique printing pattern facilitated uniform graphene dispersion within the polymer matrix. Mechanical tests revealed a 11 % increase in tensile strength and a 50 % rise in Young’s modulus at 2 wt% graphene, confirming effective reinforcement. Thermogravimetric analysis showed a 40 °C increase in degradation temperature, indicating enhanced thermal stability. Additionally, thermal conductivity improved by 170 %, and electrical percolation was achieved at just 0.5 wt% loading, enhancing electrostatic discharge safety. Molecular dynamics simulations demonstrated that graphene reduced polymer chain coiling, improved crystalline order, and strengthened hydrogen bonding within the matrix. Most notably, gas permeability tests revealed an 11-fold reduction in hydrogen permeability at 1.5 wt% filler, at least 40 % lower than state-of-the-art materials. These findings position 3D-printed graphene/PA12 nanocomposites as a superior solution for advanced, safe, and efficient hydrogen storage applications.

氢对可持续能源系统至关重要，但开发高效、经济的储氢气体屏障材料仍然是一个挑战。本研究研究了基于聚酰胺-12 （PA12）填充0-2 wt%的少层配方石墨烯油墨（PAG）的3d打印纳米复合材料的隔氢性能。一种独特的印刷模式促进了石墨烯在聚合物基体中的均匀分散。机械测试显示，在2 wt%石墨烯的情况下，抗拉强度增加11%，杨氏模量增加50%，证实了有效的增强。热重分析表明，降解温度提高了40°C，表明热稳定性增强。此外，导热性提高了170%，在0.5 wt%的负载下实现了电渗透，提高了静电放电的安全性。分子动力学模拟表明，石墨烯减少了聚合物链卷曲，改善了晶体秩序，并加强了基体内的氢键。最值得注意的是，气体渗透性测试显示，在1.5 wt%的填料中，氢气渗透率降低了11倍，比最先进的材料低至少40%。这些发现将3d打印石墨烯/PA12纳米复合材料定位为先进、安全和高效的储氢应用的卓越解决方案。

Shape memory foams (SMFs) have garnered significant attention as smart, sustainable solutions for diverse applications, including environmental remediation and thermal insulation. However, their practical utility has often been constrained by limited expansion ratios resulted poor porosity, which hinder performance in key areas such as oil absorption and heat retention. In this study, we report the fabrication of ultralight SMFs based on the environmentally friendly supercritical foaming method. The exceptional miscibility of the polymer blends, validated by molecular dynamics analysis and thermo behaviors, enables the formation of foams with an extraordinarily high expansion ratio. This process yields microcellular structures with an ultralow density of 0.0265 g cm⁻³, significantly enhancing both the porosity and surface area of the material. The high expansion ratio directly translates to superior oil absorption capacity, as the increased pore volume and interconnected microstructure facilitate rapid uptake and retention of oils. Simultaneously, the expanded cellular architecture imparts outstanding thermal insulation properties, effectively minimizing heat transfer and energy loss. The excellent shape memory behavior and recyclability, further underscoring their potential for sustainable applications. This research introduces a robust and eco-friendly strategy for producing high-performance SMFs with unprecedented expansion ratios, offering a versatile approach for environmental protection and energy conservation.

形状记忆泡沫（smf）作为一种智能、可持续的解决方案，在环境修复和隔热等各种应用中得到了广泛关注。然而，它们的实际应用往往受到有限的膨胀比的限制，导致孔隙率低，从而影响了吸油和保温等关键领域的性能。在这项研究中，我们报道了基于环境友好的超临界发泡方法制备超轻SMFs。通过分子动力学分析和热行为验证，聚合物共混物具有优异的混相性，能够形成具有极高膨胀率的泡沫。该工艺产生的微细胞结构具有0.0265 g cm−3的超低密度，显著提高了材料的孔隙率和表面积。高膨胀率直接转化为优越的吸油能力，因为增加的孔隙体积和相互连接的微观结构有助于快速吸收和保留油。同时，扩展的蜂窝结构赋予出色的隔热性能，有效地减少热量传递和能量损失。优异的形状记忆性能和可回收性，进一步强调了其可持续应用的潜力。该研究介绍了一种强大而环保的策略，用于生产具有前所未有膨胀比的高性能smf，为环境保护和节能提供了一种通用方法。

The escalating demand for high-performance electronics necessitates innovative dielectric materials capable of efficient heat dissipation and robust interfacial stability. Herein, we present an interfacial engineering approach to fabricate multifunctional polyarylene ether nitrile (PEN)-based composite films, addressing critical challenges in thermal management and wear resistance. Through designing co-deposition process, heterostructure fillers (Ag-SiCws, Ag-BNNS, and SiCws-BNNS) were synthesized and functionalized by polydopamine (PDA) and polyethyleneimine (PEI), ensuring optimal dispersion and interfacial adhesion within the PEN matrix. Results show that different heterostructure fillers are inconsistent for constructing heat transfer pathways, but all of them can achieve effective attenuation of interfacial phonon scattering. At the same time, the formation mechanism of heat conduction channels in the multi-component PEN-based films is deeply deduced with the help of finite element analysis and tribological behavior analysis. The excellent frictional performance is not only attributed to the rigid skeleton of filler, but also the synergistic effect of interfacial optimization, which effectively suppresses the accumulation of frictional heat during the sliding process. In addition, the effectiveness of interfacial optimization was further confirmed by a combination of mechanical and electrical property tests. Therefore, this study provides a way to solve the heat dissipation problem of electronic devices and to improve the stability and lifetime.

对高性能电子产品不断升级的需求需要能够高效散热和强大界面稳定性的创新介电材料。在此，我们提出了一种界面工程方法来制造多功能聚芳醚腈（PEN）基复合薄膜，解决了热管理和耐磨性方面的关键挑战。通过设计共沉积工艺，合成异质结构填料Ag-SiCws、Ag-BNNS和SiCws-BNNS，并以聚多巴胺（PDA）和聚乙烯亚胺（PEI）进行功能化，保证了PEN基质内的最佳分散和界面粘附。结果表明，不同异质结构填料在构建换热通道时存在差异，但均能有效地衰减界面声子散射。同时，借助有限元分析和摩擦学行为分析，深入推导了多组分pen基薄膜中热传导通道的形成机理。优异的摩擦性能不仅归功于填料的刚性骨架，还归功于界面优化的协同作用，有效抑制了滑动过程中摩擦热的积累。此外，力学性能和电学性能的结合试验进一步证实了界面优化的有效性。因此，本研究为解决电子器件的散热问题，提高其稳定性和寿命提供了一条途径。

A flame-retardant (FR) hydrogel with controllable size and shape was synthesized using only poly(vinyl alcohol) (PVA) and ammonium polyphosphate (APP). The self-assembled PVA-APP (PA) hydrogel was formed via hydrogen bonding, enabling customizable shapes and sizes by simply shaking and stacking. Its dimensions were up to 250 × 400 × 2 mm³. In PA-n (n = APP/PVA mass ratio; n = 4, 6, and 8), PA-6 exhibited a compressive strength of 16.17 kPa and fracture elongation of 238 %. The hydrogel can be rolled for portability and retains its structure and performance after unfolding, ensuring its suitability for long-term storage. Moreover, PA-6 achieved a limited oxygen index of 39.22 % and peak heat-release rate of 157.97 kW/m², demonstrating excellent FR properties. Organic and structural analyses before and after combustion revealed that the FR mechanism involved air pathways, phosphate radical chelation, char formation, and gas dilution. In addition, the PA hydrogel exhibited excellent thermal protection performance when applied to various substrates, including pig skin, paper, and polyurethane foam, and was effectively used as a fire blanket to suppress flames in a model car. These findings highlight the potential of PA hydrogels for broad applications in various industrial fields.

Multifunctional hydrogels often face performance trade-offs inherent in homogeneous systems, while conventional methods for constructing stratified hydrogels struggle to reconcile simplicity, stability, and functionality. Herein, we introduce Gel Alloy, a three-layer hydrogel prepared via one-step self-assembly at room temperature, characterized by its alloy-like stratified complementary structure. This innovative design enables synergistic functionality, achieving combined properties that exceed the sum of individual layers. The resulting Gel Alloy exhibits exceptional integrated performance, including flame retardancy up to 1300 °C, high compressive strength (6.8 MPa), puncture resistance (111.3 MPa), and durability in saline-wet environments. These attributes effectively overcome classical functional trade-offs in protective materials, making it suitable for packaging deflagration-prone substances. This study offers fundamental insights into synergy-driven material enhancement and opens a new avenue for designing high-performance materials for critical applications.

There are limited reports on multilayer MXene-based electromagnetic interference shielding (EMI) nanocomposites featuring low-reflectivity characteristics with MXene nanocomposite films serving as electromagnetic wave reflection layers. In this study, the first combination of asymmetric porous structures with sequence-dependent gradient loss mechanisms, a MXene/cellulose nanofiber (MC) nanocomposite film was used as the electromagnetic wave reflecting layer, while Nickel-plated multi-walled carbon nanotube/iron tetroxide-loaded reduced graphene oxide/cellulose nanofiber/waterborne polyurethane (Ni@MCNT/Fe₃O₄@rGO/CNF/WPU(NFCW)) porous nanocomposites served as the absorbing layer. Four types of NFCW&MC asymmetric multilayer-porous nanocomposites were prepared with varying assembly orders through a layer-by-layer self-assembly method. Benefiting from the asymmetric multilayer-porous structure design, all four NFCW&MC asymmetric multilayer-porous nanocomposites exhibited absorption-dominated (A over R) EMI shielding mechanisms. The loss processes of electromagnetic waves in the nanocomposites were simulated using finite element analysis. Notably, different assembly orders resulted in distinct loss mechanisms, affecting the values of A and R for the nanocomposites. In particular, the asymmetric multilayer-porous nanocomposite with the optimal assembly order demonstrated an EMI shielding effectiveness of 57.4 dB and an A value of 0.807. Therefore, the findings of this study provide valuable insights for the development of absorption-dominated MXene nanocomposites.

Carbon fiber reinforced thermoset composites (CFRP) have demonstrated significant potential for industrial applications. However, their permanent cross-linked networks pose challenges for reprocessing, repairing, and recycling. The advent of vitrimers, featuring dynamic cross-linked networks, offers a promising solution to these limitations. Herein, industrial-scale production of carbon fiber (CF) reinforced vitrimer composite was achieved using a prepreg process with a matrix of polyether sulfone (PES)-modified epoxy vitrimer (V-PES). The CF/V-PES composite exhibits suitable thermal and mechanical properties, including a glass transition temperature (T_g) of 86.2 °C and a storage modulus of 16 GPa. The dynamic transesterification reaction of vitrimer matrix imparts dynamic properties to CF/V-PES composite, enabling significant stress relaxation and creep behavior at temperatures above 200 °C, with a relaxation activation energy (E_τ) of 65.43 kJ/mol. These dynamic properties facilitate macroscopic shape memory behavior, reprocessing, and repair of interlayer cracks. The process conditions pressure, temperature, and time were optimized through orthogonal experiments. Furthermore, leveraging the dynamic transesterification reaction with ethylene glycol (EG), the V-PES matrix can be rapidly degraded in EG solution at 180 °C, enabling closed-loop recycling of CF/V-PES composites. These exceptional capabilities in reprocessing, repairing, and recycling underscore the tremendous potential of CF/V-PES composite for advanced engineering applications.

碳纤维增强热固性复合材料（CFRP）已显示出巨大的工业应用潜力。然而，它们的永久交联网络对后处理、修复和回收提出了挑战。具有动态交联网络特征的玻璃体的出现，为这些限制提供了一个有希望的解决方案。本文采用聚醚砜（PES）改性环氧玻璃体（V-PES）为基体的预浸工艺，实现了碳纤维（CF）增强玻璃体复合材料的工业规模生产。CF/V-PES复合材料具有良好的热性能和力学性能，包括玻璃化转变温度（Tg）为86.2℃，存储模量为16 GPa。在200℃以上的温度下，CF/V-PES复合材料具有明显的应力松弛和蠕变行为，弛豫活化能（Eτ）为65.43 kJ/mol。这些动态特性有利于宏观形状记忆行为、再加工和层间裂纹的修复。通过正交试验对工艺条件、压力、温度、时间进行优化。此外，利用与乙二醇（EG）的动态酯交换反应，V-PES基质可以在180°C的EG溶液中快速降解，从而实现CF/V-PES复合材料的闭环回收。CF/V-PES复合材料在后处理、修复和回收方面的卓越能力凸显了其在先进工程应用方面的巨大潜力。

The escalating environmental challenges posed by conventional plastics have amplified the importance of biodegradable polymers as sustainable alternatives. However, addressing their recyclability and reprocessing is critical to enhancing their environmental and economic viability. This review delves into the multiple reprocessing of biodegradable polymer blends, focusing on mechanical recycling's effects on their structure, properties, and performance. Unlike single polymers, blends offer tailored properties by combining the strengths of individual components, making them more suitable for diverse applications. However, their complex morphologies and phase interactions demand unique strategies for effective recycling.

Key findings highlight that polymer blends, such as PLA/PHB and PLA/PBAT, exhibit greater resilience to repeated processing compared to their pure counterparts, owing to enhanced intermolecular interactions and progressive crystallinity. Compatibilizers, including chain extenders like Joncryl®, play a pivotal role in mitigating degradation by improving phase adhesion and maintaining mechanical and thermal properties. Rheological analyses reveal the critical interplay between phase morphology and processing conditions, emphasizing the importance of tailoring blend compositions and additives for optimal recyclability.

This review sets itself apart by providing the first comprehensive examination of the effects of multiple mechanical reprocessing cycles specifically on biodegradable polymer blends, filling a significant gap in the literature. By addressing current challenges, it offers a roadmap for advancing biodegradable materials toward a circular economy.
