Abstract The design and fabrication of high toughness electromagnetic interference (EMI) shielding composite films with diminished reflection are an imperative task to solve pollution problem. Ternary MXene/ANF (aramid nanofibers)–MoS 2 nacre-like layered structure here fabricated after the introduction MoS into binary system. fulfills impressive “kill three birds one stone” improvement effect: lubrication toughening mechanical performance, reduction in secondary wave, performance photothermal conversion. After (mass ratio 50:50), strain failure tensile strength increase from 22.1 $$\pm$$ ± 1.7% 105.7 6.4 MPa 25.8 0.7% 167.3 9.1 MPa, respectively. elevates 13.0 4.1 26.3 0.8 MJ m −3 (~ 102.3%) simultaneously. And effectiveness (SE R ) 50:50) decreases ~ 10.8%. EMI (EMI SE) 41.0 dB (8.2–12.4 GHz); 60:40), increases 18.3 1.9% 28.1 53.5%), SE 22.2%, corresponding is 43.9 dB. also leads a more efficient conversion 45 55 °C). Additionally, MXene/ANF–MoS exhibit excellent electric heating quick temperature elevation (15 s), cycle stability (2, 2.5, 3 V), long-term (2520 s). Combining MXene content, ternary could be applied many industrial areas. This work broadens how achieve balance between properties versatility composites case high-function fillers.

Abstract 2D materials with ultrathin structure, high specific areas, and excellent mechanical properties provide potentials to enhance the electrical, mechanical, chemical of metals. In particular, MXene different compositions, abundant surface terminations, electrical conductivity has good affinity some metals such as Al, Li, Na well can be uniformly dispersed in Moreover, above unique features enable MXene–metal hybrids diversified functions. this review, current advanced studies topic are summarized. The MXenes properties, conductivity, wettability, first reviewed. Subsequently, synthetic approaches including physical, metallurgy, electrochemical, wet‐chemical routes screened. By harnessing features, could hybrids, their application energy storage devices, anticorrosion coating, functional structural materials, electromagnetic wave absorption highlighted. Finally, an outlook on in‐operando characterization techniques is provided clarify strengthening mechanism metals, tailoration interface between urgent need for industrial‐scale manufacture hybrids.
