However, present reports by this strategy synthesizing anisotropic nanoparticles mainly focus on single component, and require an additional oil drop template and subsequent removal. Consequently, the controllable fabrication of hybrid Janus particles (HJPs) containing organic-inorganic components simultaneously in one-pot emulsion still suffers a great challenge. Here, snowman-like, popcorn-like, and mulberry-like HJPs, composed of 3-aminophenol-<em>co</em>-formaldehyde polymer and mesoporous SiO₂, were tailored successfully using a one-pot emulsion self-template induction strategy, and an interface anisotropic assembly mechanism was revealed, elucidating their growth process. Ascribed to abundant mesopores and well-defined composition partitions, as-prepared snowman-like HJPs with adjustable overall sizes and two end sizes can be used as a carrier of color-developing agent and a compatibilizer between linseed oil and waterborne polyurethane to construct self-reporting and self-healing intelligent anticorrosive coating. Generally, our findings not only open up a new direction for the application of HJPs in functional coatings, but also provide guidelines for the emulsion self-template inducing HJPs with precise architecture and innovative function design.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"303 ","pages":"Article 112616"},"PeriodicalIF":12.7,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144071871","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}

A 3D snowflake-patterned PDMS skeleton is designed to host an interconnected MXene network, achieving exceptional thermal conductivity (1.32 k/W·m, 680 % enhancement over pure PDMS) and flame retardancy (33 % reduction in peak heat release rate, 90.3 % residue retention). Simultaneously, the perovskite overlayer enables real-time temperature visualization through reversible color transitions (yellow → red → black) within 15 s, triggered by phase transformations at critical thresholds (60–120 °C). The Janus architecture spatially decouples functional units while ensuring synergistic interactions, offering dual protection against thermal hazards: rapid heat dissipation via MXene pathways and proactive fire warning via thermochromic responses. Demonstrated in battery thermal management, the composite reduces surface temperatures by 19.1 °C under high discharge rates (6.16C), highlighting its potential for safeguarding miniaturized and high-power electronic systems.

In 1952, Cox's interfacial stress transfer model underscored the critical roles of interfacial thickness and modulus in determining interfacial debonding stress. Although the model remains foundational in understanding stress transfer mechanisms in FRRC, its application has been limited by the challenges in quantitatively measuring these interfacial parameters. This study addresses this gap by developing a polishing technique that integrates mechanical and ion beam polishing, specifically tailored for FRRC. By optimizing key parameters, including rubber thickness on fiber surface, ion beam polishing voltage and temperature, and fiber monofilament density, ultra-flat surfaces on micron-fiber cord/elastomer composites have been achieved. This enabled the successful visualization of the intricate tri-phase, two-interface structure using the quantitative nanomechanical mapping technique of atomic force microscopy (AFM-QNM). The interfacial thickness and modulus were then quantitatively characterized using AFM-QNM and nanoindentation techniques. Thus, the interfacial shear strength and debonding stress were successfully calculated using the KT and COX models. Using RFL-treated nylon 66 fiber/rubber composites as a case study, based on the quantitative characterization of interfacial thickness and modulus, the interfacial shear strength and interfacial debonding stress were quantified as 5.63 MPa and 112.14 MPa, respectively.

This investigation systematically elucidates the high-temperature structural evolution mechanisms of boron nitride (BN) and alumina (Al₂O₃) fibers, with particular emphasis on the first discovery of biomimetic conchoidal-like layered architecture in BN fibers demonstrating multiscale toughening mechanisms. The hierarchical structure consists of hexagonal BN grains aligned along the fiber axis, which are interlocked to form an intricate three-dimensional network. Under mechanical stress, this architecture exhibits multi-level coordinated responses: Lamellar grain boundary sliding induces crack deflection along intercrystalline paths, and non-close-packed BN grains undergo stress-induced rotation to dissipate energy. These synergistic mechanisms collectively sustain fiber pull-out effects. Benefiting from the thermal stability of covalent B–N bonds coupled with continuous energy dissipation through 2D boundary sliding, the bending strength retention rate of BN fibers after sintering at 1400 °C is 57.67 % relative to their bending strength at room temperature, whereas for Al₂O₃ fibers, the bending strength retention rate after sintering at 1400 °C is only 7.26 % compared to their room-temperature value. Following sintering at 1400 °C, the bending strength retention rate of BN fibers exhibits a 794 % enhancement compared to that of Al₂O₃ fibers.

Static and cyclic compression tests were conducted to evaluate load-bearing capacity, energy absorption, and failure mechanisms. X-ray computed tomography (CT) analysis was performed to examine interfacial behavior between the lattice and cement matrix. Results indicate that 3D auxetic lattices significantly enhance strength and ductility through multidirectional lateral confinement, where the energy absorption increased by up to 2.8 times compared to unreinforced foamed cement at a density of 550 kg/m³. Specifically, the 3D auxetic lattices reinforced composites showed pronounced resilience under cyclic loading, exhibiting gradual and ductile damage evolution while sustaining performance beyond 700 cycles. In comparison, 2D auxetic lattices which provide negative Poisson's ratio only in-plane are less effective in reinforcing foamed cement matrix. Additionally, although non-auxetic lattice increased load-carrying capacity to some degree, the corresponding composites structure showed localized shear failure and premature structural degradation under cyclic loading. Overall, the active reinforcement effect of auxetic lattices enables the development of advanced foamed cementitious composites for impact mitigation, blast protection, and buoyant components requiring energy absorption and repeated-load resilience.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"303 ","pages":"Article 112614"},"PeriodicalIF":12.7,"publicationDate":"2025-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143948134","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 S-PI exhibited excellent thermal stability, with a T_{1 %} (temperature at 1 % weight loss) of 400.5 °C. Furthermore, it formed a stable water-based sizing agent via self-emulsification.

Therefore, the aging-related evolution of the physio-chemical prepreg state (conversion, T_g, water uptake, viscosity) is examined in terms of its impact on processing (forming properties, tack), applied cure cycles (temperature, dwell time, pressure) and post-cure laminate quality (porosity, mechanical performance).
