Abstract

With the continuous exploration of the extreme environment in space, strong space radiation and extreme high temperature environment have brought great challenges to the research work of astronauts. This study effectively created the SiO₂/SWCNT@Ni composite film with electromagnetic shielding and thermal insulation performances by a high-temperature carbon reduction process utilizing the SiO₂ nanofiber, the poly(vinyl alcohol) (PVA) solution of single-walled carbon nanotubes (SWCNT), and Ni(NO₃)₂ as raw ingredients. The adaptable SiO₂ nanofiber membrane was synthesized by sol–gel and electrospinning methods utilizing tetraethyl n-silicate hydrolysis precursors as the primary ingredients. At a result, when the content of SWCNT content is 9 wt%, the average EMI SE_T of SiO₂/SWCNT₉@Ni is 39.4 dB, and the thermal conductivity measures 0.0405 W/m·K. In addition, SiO₂/SWCNT₉@Ni shows a good flame-retardant performance. Consequently, this research holds significant reference value in the field of manned spaceflight.

Graphical abstract

SiO₂/SWCNT@Ni composite film with sandwich structure has excellent electromagnetic shielding and thermal insulation performances.

期刊介绍： Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field. The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest. Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials. Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
