Building ordered oriented architectures while maintaining the material's mechanical robustness remains challenging. Inspired by the vertically bristle structure of gecko toes, this study proposes a magnetic‐thermal synergistic strategy for fabricating robust aramid nanofiber aerogels with a vertically oriented spatial structure. Under the influence of magnetic torque and magnetic attraction, magnetic carbon nanotubes spontaneously align to form an ordered vertically oriented architecture (direction fit of 96%). This architecture enhances the sensing signal intensity of the aerogel by 64% by inducing surface charge migration. The thermally crosslinked effect enhances the bonding strength between aerogel fiber networks, enabling the aerogel to achieve a compressive strength of 682 kPa (80% compressive strain). This surpasses the compressive strength of aramid fiber aerogels reported to date. The vertically oriented aerogel is assembled into a self‐powered pressure sensor, achieving a signal recognition rate of 98.2% with machine learning assistance. This study proposes a non‐invasive spatial microstructure regulation strategy, offering new insights into the construction of anisotropic structural materials.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"127 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145282759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Porous Mg structure has been proposed as a promising strategy due to its high storage capacity and ability to accommodate volume expansion. However, challenges such as sluggish kinetics and structural degradation resulting from instability due to vacant sites still remain. In this study, a tailored design of porous Mg structure with site‐specific transition metal dual‐doping and structure‐reinforced carbon nanotube (CNT)‐framework is presented for optimal hydrogen storage. Ti and Ni are strategically deposited on the surface to synergistically enhance hydrogen sorption kinetics by facilitating hydrogen dissociation and diffusion, while CNTs are interpenetrated into 3D Mg structure for improving thermal conductivity and maintaining the porous structure. The resulting composite demonstrates exceptional performance, achieving hydrogen absorption and desorption of 4.8 and 5.8 wt%, respectively, within 10 min with an impressively low activation energy for absorption of 46 kJ mol−1 H2. Even after 50 cycles, its capacity and porous structure are well preserved, showing excellent cyclability in comparison with previously reported materials. This delicate design strategy based on a comprehensive understanding of structural and chemical characteristics is key to maximizing the targeted performance.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"1 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145282905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main challenge for 2D COFs anodes lies in their insufficient rate capability and cycle life, which stem from the limited interlayer spacing of the π‐stacking structure that is incompatible with large‐radius K+ ions, together with the high electron/ion diffusion barriers. Herein, a novel hydrazone‐linked COF composite (HT‐COF@G) is fabricated from a new module of 2,3,8,9,14,15‐hexa(4‐hydrazidocarbonylphenyl)hexaazatrinaphthalene with 2,4,6‐tris(4‐formylphenyl)‐1,3,5‐triazine linker on graphene support. Physical and structural characterization reveals the preeminent electric conductivity (12.53 S m−1), well‐defined mesopores (2.40 nm), and particularly large interlayer spacing (0.46 nm) of HT‐COF@G, facilitating the efficient K+/e− transport and storage. Atomic force microscopy images confirm the formation of ultrathin HT‐COF@G nanosheets (≈3.6 nm), significantly reducing the K+ transport distance. These features, in combination with the various redox active sites for storing K+ ions, result in a record‐high reversible capacity (534 mA h g−1 at 0.2 A g−1), impressive rate performance (133 mA h g−1 at 10 A g−1), and extraordinary cycling stability (261.9 mA h g−1 at 5 A g−1 with 100% retention up to 5000 cycles) for HT‐COF@G among organic electrodes.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"18 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145282702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, molecular engineering strategies are employed to design and synthesize novel high‐performance photosensitive polyimide inks, incorporating both methacrylate (photo‐curable) and benzoxazine (thermal cross‐linkable) functional groups. During the 3D printing process, ultraviolet exposure initiates the photopolymerization of methacrylate, forming flexible covalent networks. Subsequent thermal treatment induces the ring‐opening polymerization of benzoxazine, resulting in the formation of a rigid phenolic‐aromatic network that shuttles the 3D architecture. Mechanistic investigations reveal that the development of a dual interpenetrating network comprising both soft and hard phases significantly enhances interlayer bonding and eliminates anisotropy in printed materials. Consequently, the 3D polyimide structures exhibit exceptional thermal stability under load (HDT > 165 °C), superior isotropic mechanical properties (elastic modulus > 1.1 GPa, and elongation at break > 8.5 %), and high dimensional accuracy (shrinkage <1%). This approach establishes a general platform for the rapid fabrication of high‐performance 3D structures with robust interlayer connectivity, offering a promising solution to the limitations of conventional additive manufacturing techniques.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"1 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145282703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It inspired scientists and engineers to develop different applications, including those based on conductivity, magnetism or reactivity, and to design light‐responsive materials that can sense, adapt, and self‐heal under illumination. Often, photoactive molecules that can reversibly undergo photoisomerization serve as the key component to achieve light‐switching of functionalities in advanced materials for reconfigurable electronics or light‐controlled information storage and processing. However, when used in bulk or solution, they face limitations such as aggregation or restricted isomerization. Their integration into frameworks materials overcomes these challenges, paving the way for new photoprogrammed materials. This review shows the potential of framework materials for light‐switched conduction, focusing specifically on proton and electron conduction photoswitching. This work reviews the recent progress in state‐of‐the‐art and explains the mechanisms driving the photoresponse, including the Grotthuss mechanism for proton transport, the hopping mechanism for electron conduction, and other charge transfer (CT) pathways. Strategies that are employed to improve photoswitchable conduction are elaborated.
