Demand for lightweight and efficient electromagnetic wave (EW) absorbers continues to increase with technological advances in highly integrated electronics military applications. Although MXene-based EW have been extensively developed, more coupling thinner thickness are still essential. Recently, ordered heterogeneous materials emerged as a novel design concept address the bottleneck faced by current material development. Herein, an heterostructured engineering assemble Ti3 CNTx MXenes/Aramid nanofibers/FeCo@SiO2 nanobundles (FS) aerogel (AMFS-O) is proposed, where commonly disordered magnetic composition transformed FS arrays that provide powerful loss capacity. Experiments simulations reveal anisotropy networks enhance response field vector of EW, which effectively improves impedance matching makes reflection (RL) peaks shift lower frequencies, leading thickness. Furthermore, temperature stability excellent compressibility AMFS-O expand functionalized The synthesized achieves full-wave absorption X Ku-band (8.2-18.0 GHz) at 3.0 mm RLmin -41 dB low density 0.008 g cm-3 . These results suggest effective strategy designing high-performance multifunctional absorbers.

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.
