MXene nanomaterials stand out among 2D and have been extensively studied by researchers because of their unique layered structure, chemical diversity, outstanding physical properties. In recent years, materials rapidly opened the market for electromagnetic interference shielding technology due to excellent wave absorption (EMA) capability. However, so far, compared with development (EM) technology, there is still much room in construction MXenes application absorption. Herein, strategies, conversion mechanism, applications are reviewed. Through meticulous material design an interdisciplinary approach, expected become one smart tunable absorbers, scenarios will also broader.

Abstract Transition metal carbides/nitrides (MXenes) demonstrate a massive potential in constructing lightweight, multifunctional wearable electromagnetic interference (EMI) shields for application various fields. Nevertheless, it remains challenging to develop facile, scalable approach prepare the MXene‐based macrostructures characterized by low density, thickness, high mechanical flexibility, and EMI SE at same time. Herein, ultrathin MXene/reduced graphene oxide (rGO)/Ag foams with porifera‐inspired hierarchically porous microstructure are prepared combining Zn 2+ diffusion induction hard template methods. The hierarchical porosity, which includes mesoporous skeleton microporous MXene network within skeleton, not only exerts regulatory effect on stress distribution during compression, making rubber‐like resistant wrinkling but also provides more channels multiple reflections of waves. Due interaction between Ag nanosheets, MXene/rGO, structure, is possible produce an outstanding shielding performance specific surface effectiveness reaching 109152.4 dB cm 2 g −1 . Furthermore, exhibit multifunctionalities, such as transverse Joule heating, longitudinal heat insulation, self‐cleaning, fire resistance, motion detection. These discoveries open up novel pathway development lightweight materials considerable anti‐interference devices.

Abstract Constructing flexible and robust thermally conductive but electrically insulating composite films for efficient safe thermal management has always been a sought-after research topic. Herein, nacre-inspired high-performance poly(p-phenylene-2,6-benzobisoxazole) (PBO)/MXene nanocomposite film was prepared by sol-gel-film conversion method with homogeneous gelation process. Because of the as-formed optimized brick mortar structure, strong bridging caging effects fine PBO nanofibre network on MXene nanosheets, resulting is (2.5 × 10 9 Ω cm), exhibits excellent mechanical properties (tensile strength 416.7 MPa, Young’s modulus 9.1 GPa toughness 97.3 MJ m −3 ). More importantly, synergistic orientation nanofibres nanosheets endows an in-plane conductivity 42.2 W −1 K . The also stability flame retardancy. This work broadens ideas preparing composites.

Gallium-based liquid metal (LM) with intriguing high electrical conductivity and room-temperature fluidity has attracted substantial attention for its potential application in flexible electromagnetic interference (EMI) shielding. However, the EMI shielding performance of existing LM-based composites is unsatisfying due to irreconcilable contradiction between efficiency (SE) low thickness. In addition, research on environmentally stable material become an urgent need increasingly sophisticated scenarios. Herein, we prepared a reduced graphene oxide (rGO) bridging LM layered heterostructure nanocomposite liquid-infused slippery surface (S-rGO/LM), which exhibits ultrahigh X-band SE 80 dB at mere internal thickness 33 μm, extremely value 100 67 μm. More significantly, protected by ultrathin (2 μm) yet effective surface, S-rGO/LM film exceptional stability (EMI stays above 70 dB) after enduring various harsh conditions (harsh chemical environments, extreme operating temperatures, severe mechanical wearing). Moreover, also demonstrates satisfying photothermal behavior excellent Joule heating (surface temperature 179 °C 1.75 V, thermal response <10 s), endows it capability anti-icing/de-icing. This work proposes way construct reliable high-performance capability, shows great applications wearable devices, defense, aeronautics astronautics.
