The successive ionic layer adsorption and reaction (SILAR) technique is used to prepare a range of NTCS thin films, as battery like electrode, and the optimized NTCS3@NF electrode displayed exceptional results, overtaking all previously reported ternary sulfides. The NTCS3@NF electrode achieved an impressive specific capacity (Cs) of 1708 C/g at 5 A/g, with 100 % capacity retention and coulombic efficiency after 20,000 cycles. The superior performance of the introduced electrodes is attributed to the effective direct growth of thin film over an excellent conductive substrate and avoiding creating dead surface area by using polymer binders. The inherent connection between the prepared thin film and substrate decreases the overall resistance and facilitates electron transfer across the interface. Also, the thin film porosity helps in effective ion diffusion between the electrode/electrolyte interface. Moreover, the NTCS3@NF//Activated Carbon (AC)@NF hybrid supercapacitor device (HSC) delivered an outstanding energy density (ED) of 20 Wh/kg and a power density (PD) of 12,909 W/kg at 10 A/g, retaining 76 % capacity and 81.2 % coulombic efficiency even after 100,000 cycles, surpassing the performance of leading HSCs.

This paper proposes a complete skin electronic platform (which encompasses three main parts: surface-localized silver-enriched elastic conductors (SSECs)), solderable copper pads and medical dressing. The high-performance SSECs was prepared through gravity induced sediments of silver nanoflakes, which not only exhibit extremely low sheet resistance of 4.8 mΩ/sq (the conductivity is 5.12 × 10<sup>6</sup> S/m) but also superior stretchability (up to 300 %). The resistance variation of SSECs upon stretching is very small, which can satisfy the application requirements as analog circuit systems. Copper pads embedded in SSECs not only solve the problem of interconnecting with commercial rigid components and integrated circuits but also solve the problem of nagging issue of vulnerable connections between rigid and soft parts. The SSECs can be integrated into a permeable medical dressing by lamination, which is fully compatible and strong adhesion to the skin. As a demonstration, a skin circuit has been fabricated as the platform to integrate a temperature sensor and rigid circuitry to establish a skin temperature sensing system. Accurate temperature measurements can be maintained with only 0.3 % variation even at large wrist bending movements, adequately demonstrated the reliability and practicality of this innovative approach as a potentially universal platform and expected to have a broad application prospect.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"299 ","pages":"Article 112412"},"PeriodicalIF":12.7,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143685399","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}

S-WPC was fabricated utilizing self-developed co-extrusion molding equipment and incorporating high-strength, high-ductility GFRP bolts as reinforcing elements. The S-WPC with 5 bolts exhibited substantial improvements compared to the control WPC. Specifically, there was a 441.7 % increase in flexural strength, a 46.5 % increase in modulus, and an outstanding 1168.0 % improvement in ductility. Additionally, flexural deflection reached 14.2 cm, while the work of rupture showed a remarkable improvement of 4946.0 %. Furthermore, the linear expansion coefficient and 1000-h creep strain were reduced by 85.4 % and 68.6 %, respectively. The integration of the bolt's threaded structure with nuts allows for secure attachment of WPC to load-bearing structures such as floor slabs and shear walls. The flexural performance of S-WPC under fixed-end constraints was evaluated using a custom steel frame structure, revealing a substantial enhancement over traditional WPC. The flexural strength of S-WPC reached 422 MPa, a 2055 % increase compared to the control WPC, surpassing the performance of wood-based panels, structural bamboo scrimber, and other conventional building materials. Finite element simulation was employed to optimize the structure, explore optimal structural design, and assess theoretical load-bearing capacity.
