During the first immersion in the LMD process, Ni selectively dissolved from a (Fe₈₀Cr₂₀)₅₀Ni₅₀ precursor into the pure Mg melt, resulting in the formation of a 3D interconnected FeCr–Mg composite. The subsequent alloying with Y or Al in Mg melt induced distinct microstructural evolutions and mechanical properties. Y did not react with the FeCr ligaments but instead incorporated a secondary plate-shaped Mg₂₅Y₄ intermetallic phase within the soft Mg region. In contrast, Al addition caused significant microstructural modifications, including the formation of a thick Al-alloyed layer at the solid ligament and an ordered <i>B2</i> phase. Particularly, the Al alloying reaction within the ligament increased the volume fraction of the solid phase during the subsequent alloying process. Furthermore, the Al-alloyed layer acted as a heterogeneous nucleation site during solidification, leading to the formation of Mg nanograins with a fine lamellar β-Mg₁₇Al₁₂ phase. The 3D interconnected multi-heterostructures, FeCr–(Mg–Mg₂₅Y₄) and FeCr–(FeCrAl)–(Mg₉₀Al₁₀), exhibited distinct mechanical properties compared to the unimodal FeCr–Mg composite, demonstrating higher yield strength and ultimate tensile strength. These findings underscore the potential of hierarchical 3D interconnected multi-heterostructures for enhancing the mechanical performance of advanced composite materials through tailored alloying strategies.\u0000</p></div>","PeriodicalId":7220,"journal":{"name":"Advanced Composites and Hybrid Materials","volume":"8 5","pages":""},"PeriodicalIF":21.8,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s42114-025-01442-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145210830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the poor compatibility and dielectric mismatch between the nanofillers and the polymer matrix still cannot be well settled simultaneously at present. Herein, a novel interfacial engineering strategy using the covalent organic framework (COF) material is firstly employed to concomitantly tackle the above issues and achieve improved energy storage performance for the polymer-based dielectric nanocomposites. Specifically, the poly(vinylidene fluoride-co-hexafluoro propylene)/poly(methyl methacrylate) (P(VDF-HFP)/PMMA)–based nanocomposite with an ultra-low content of 0.5 wt% core–shell structured BaTiO₃@COF nanofillers exhibits an enhanced breakdown strength of 766.5 MV/m, yielding a high discharged energy density of 26.1 J/cm³, which outperforms the energy storage performance of most current PVDF-based/PMMA binary blend polymer composite dielectrics. More intriguingly, abundant experimental and theoretical evidence comprehensively demonstrates that the interfacial COF shell not only enhances the dielectric response but also improves the breakdown strength of the nanocomposites due to its higher electron affinity, which can act as the robust electron trap. Taking a step further, the dielectric capacitor based on the above nanocomposite film is fabricated as a device demonstration for practical application. This work manifests a new approach to breaking the intractable trade-off relation between the enhanced permittivity and decreased breakdown strength of the nanocomposite and achieving high-performance composite dielectrics for capacitive energy storage.</p></div>","PeriodicalId":7220,"journal":{"name":"Advanced Composites and Hybrid Materials","volume":"8 5","pages":""},"PeriodicalIF":21.8,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s42114-025-01468-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145210400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To solve this problem, additive manufacturing (AM), also known as 3D printing, has become widely used for on-demand infrastructure construction. While 3D printing offers faster build times and greater design flexibility, it is limited by slow-setting concrete, interruptions to install supports, and the massive environmental impact of cement, which accounts for around 8% of global CO₂ emissions. This work introduces a 3D printable, clay-based construction material that provides structural properties comparable to concrete yet cures immediately after printing. Thermally initiated frontal polymerization of an acrylamide-based binder enables setting during extrusion, allowing layers to be printed consecutively. While 3D printed concrete is typically comprised of 30–60% cement binder, our material contains 70–80 wt.% biobased materials, which can be obtained in situ. The printed material reaches buildable strengths of 3 MPa immediately after printing, enabling construction of multilayer walls and freestanding overhangs such as framing or roofs. Furthermore, the material surpasses 17 MPa, the strength required of residential structural concrete, in just 3 days, whereas traditional concrete can take up to 28 days.

The SH − TENG is fabricated using a self-healing Ecoflex (SH − Ecoflex) synthesized through the polymerization of an Ecoflex–polyborosiloxane (PBS) hybrid double network elastomer. The SH − Ecoflex exhibits high tensile strength, exceptional stretchability (590%), and autonomous mechanical self-healing efficiency (68% in 2 h).

The SH − TENG effectively charges the capacitor within a short time to power the digital thermo-hygrometer, and offers self-powered sensing functionality to monitor human joint movements. Furthermore, the handwriting touch panel is designed with a diagonal strip-void electrode-based SH − TENG to enhance the perception of finger sliding and generate a distinct electrical signal for each handwritten letter. Through the integration of a deep learning model, an advanced handwriting recognition system has been developed to recognize five handwritten letters with an average accuracy of 99%, demonstrating its potential for future applications in intelligent tactile perception and human–machine interaction, as well as signature and user recognition systems.\u0000</p></div>","PeriodicalId":7220,"journal":{"name":"Advanced Composites and Hybrid Materials","volume":"8 5","pages":""},"PeriodicalIF":21.8,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s42114-025-01479-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145210733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present work, a novel bent-core liquid crystal (BCLC) (<b>6-F-OH)</b> is infused with the polyvinylidene fluoride (PVDF) host that demonstrates an augmented piezoelectric performance with an elevated electrical conductivity. A simple yet cost-effective fabrication process is employed to achieve high-efficiency piezoelectric polymer composite free-standing films with improved flexibility for future-ready wearable device applications. A comprehensive investigation of the role of BCLCs in promoting the electroactive polar β-phase within the host polymer is conducted. The energy harvesting performances were evaluated at varying frequencies for the optimization of the BCLC-infused composite-based piezoelectric devices. The result reveals a maximum piezoelectric performance at 3 wt.% concentration of BCLC producing an output open-circuit voltage (<i>V</i>_OC) of ≈ 25 <i>V</i>_PP and short circuit current (<i>I</i>_SC) of ≈ 700 nA, a multi-fold enhancement as compared to pristine PVDF-based devices. Moreover, the composite film with 3 wt.% BCLC/PVDF demonstrates the highest remnant polarization and dielectric constant value among all the samples. The effective rise in the electrical conductivity of the BCLC-infused composite at an optimized weight fraction over its pristine PVDF counterpart is also discussed based on the percolative pathways produced by the BCLCs at the interfaces of the composite domains. Finally, some of the applications of the devised organic energy harvesters are demonstrated.
