Nitrogen-Doped Magnetic-Dielectric-Carbon Aerogel for High-Efficiency Electromagnetic Wave Absorption

Nano-Micro Letters, Год журнала: 2023, Номер 16(1)

Опубликована: Ноя. 17, 2023

Abstract Carbon-based aerogels derived from biomass chitosan are encountering a flourishing moment in electromagnetic protection on account of lightweight, controllable fabrication and versatility. Nevertheless, developing facile construction method component design with carbon-based for high-efficiency wave absorption (EWA) materials broad effective bandwidth (EAB) strong yet hits some snags. Herein, the nitrogen-doped magnetic-dielectric-carbon aerogel was obtained via ice template followed by carbonization treatment, homogeneous abundant nickel (Ni) manganese oxide (MnO) particles situ grew carbon aerogels. Thanks to optimization impedance matching dielectric/magnetic components aerogels, (Ni/MnO-CA) suggests praiseworthy EWA performance, an ultra-wide EAB 7.36 GHz minimum reflection loss (RL min ) − 64.09 dB, while achieving specific 253.32 dB mm −1 . Furthermore, reveals excellent radar stealth, infrared thermal management capabilities. Hence, high-performance, easy fabricated multifunctional nickel/manganese oxide/carbon have application aspects protection, electronic devices aerospace.

Diverse Structural Design Strategies of MXene-Based Macrostructure for High-Performance Electromagnetic Interference Shielding

Nano-Micro Letters, Год журнала: 2023, Номер 15(1)

Опубликована: Ноя. 2, 2023

Abstract There is an urgent demand for flexible, lightweight, mechanically robust, excellent electromagnetic interference (EMI) shielding materials. Two-dimensional (2D) transition metal carbides/nitrides (MXenes) have been potential candidates the construction of EMI materials due to their great electrical electroconductibility, favorable mechanical nature such as flexibility, large aspect ratios, and simple processability in aqueous media. The applicability MXenes has intensively explored; thus, reviewing relevant research beneficial advancing design high-performance MXene-based shields. Herein, recent progress macrostructure development reviewed, including associated mechanisms. In particular, various structural strategies are highlighted explored. end, difficulties views future growth shields proposed. This review aims drive macrostructures on basis rational high-efficiency utilization MXene.

Dual Cross‐Linked Magnetic MXene Aerogel with High Strength and Durability Enables Multifunctionality

Advanced Functional Materials, Год журнала: 2024, Номер 34(33)

Опубликована: Апрель 1, 2024

Abstract The construction of lightweight yet robust, durable magnetic transition metal carbides and/or nitride (MXene) aerogels is highly desired for assembling high‐performance, multifunctional architectures. However, the fabrication and application MXene severely restricted by their inferior mechanical strength poor water/oxygen resistance. Here, sustainable cellulose nanofibrils (CNFs) are employed assisting in physical chemical dual cross‐linking to strongly bind MXenes MOF‐derived nanoparticles. dual‐crosslinked (D‐MMAs) achieve a density as low 12 mg cm −3 , acquire significantly improved up 1311% over physically crosslinked ones, well remarkably hydrophobicity, oxidation stability. Furthermore, integration efficient tunable electromagnetic wave (EMW) absorption, remarkable photothermal conversion, thermal insulation, prominent oil‐water separation, thin/thick oil dye absorption capability, remote controllability accomplished. Notably, D‐MMA performs maximum intensity −63.9 dB, accomplishes specific reflection loss −1105 dB mm −1 comparable best MXene‐based EMW absorbers ever reported. Given its facile, scalable, manufacturing approach, D‐MMAs hold great prospects various fields next‐generation electronics, special equipment protection, defense, aerospace.
