Thin-film based micro-supercapacitors (TF-MSCs) have generated an increasing interest in the research on supercapacitors owing to their suitability for integration as energy storage devices in the flexible and wearable electronics, such as equipment for telecommunication and health applications. However, the complex and harsh preparation conditions limit the further development of the TF-MSCs. In this study, a simple and facile route is employed to prepare high-performance and good-integration MSCs. The porous Sb2S3@polyaniline (PANI) films are prepared in-situ by the electrochemical deposition. Subsequently, an interdigital TF-MSC is assembled using a simple method of scribing with Sb2S3@PANI as the negative electrode and activated carbon as the positive electrode. This TF-MSC achieves a high energy density of 2.26 μWh cm−2 at a power density of 0.1 mW cm−2, corresponding to a capacitance of 18.44 mF cm-2. It also exhibits a good cyclic stability (80% after 2000 cycles at 0.25 mA cm-2) and a low-rate self-discharge process. Furthermore, benefitting from the scalability of the TF-MSC fabrication, an in-plane integrated TF-MSC array is manufactured with five devices in series. Such a 5-MSC array could be applied as the energy supply component in miniature and integrative electronics. © 2023, The Authors. All rights reserved.

High-temperature effects on the compressive behaviors of SiC-coated carbon-bonded carbon fiber composites: Insights into mechanical properties and cyclic deformation recovery

Journal of Materials Research and technology 2025年 36卷 8264-8276页

Porous SiC-coated carbon-bonded carbon fiber composites (SiC-coated CBCFs) are fabricated via chemical vapor deposition (CVD) method, where silicon carbide coatings are uniformly applied to carbon fibers bonded by pyrolytic carbon while preserving their three-dimensional interconnected pore structure. The mechanical responses of SiC-coated CBCFs under elevated temperatures are systematically characterized through quasi-static compression testing coupled with multiscale microstructural analysis. The results demonstrate a monotonic decrease in elastic moduli as temperature increases to 2000 °C. In contrast, compressive strengths initially rise and then experience a slight fluctuation before the significant decrease. Under stepwise cyclic compressive loading, both the deformation recovery ability and load-bearing stiffness exhibit notable degradation at elevated temperatures, highlighting the need for larger safety margins in realistic thermal insulation scenarios. These findings establish quantitative correlations between thermomechanical degradation mechanisms and operational limits, offering valuable insights for their design and application in reusable high-performance systems.

Controlled synthesis of silicon carbide whiskers via nickel-based alloy catalyst-assisted carbothermal reduction unraveling vapor-liquid-solid growth and Ni3Si2 droplet dynamics

Silicon carbide whiskers (SiCw) are highly promising for ultra-high-temperature thermal protection systems due to their excellent mechanical properties and heat resistance. However, precisely controlling their size and shape during production remains challenging. This study achieved the controllable preparation of SiC whiskers (70–280 nm in diameter, aspect ratios of 50–300) via nickel-alloy-catalyzed carbothermal reduction. The vapor-liquid-solid (V-L-S) mechanism dominated the growth, with dynamically evolving Ni-Si alloy droplets playing a critical role. Combined experimental and thermodynamic analyses confirmed that Ni3Si2 alloy droplets stabilized above 1000 °C regulated whisker growth through a dual-pathway mechanism: adsorption of CO(g), Si(g), and SiO(g) to drive axial growth while synchronously precipitating amorphous SiO2 layers to suppress radial expansion. First-principles DFT calculations revealed strong adsorption of CO and SiO on the Ni3Si2(101) surface (adsorption energies: 1.459 eV and 2.677 eV), inducing 53.8 % and 49.2 % elongations of C-O and Si-O bonds, respectively. These findings elucidate alloy catalysts' atomic-scale "adsorption-activation-nucleation" mechanism in V-L-S growth and provide critical insights for designing SiCw-reinforced thermal protection materials. © 2025 Elsevier Ltd and Techna Group S.r.l.
