Abstract The preparation of core–shell structured nanoparticles using the galvanic replacement reaction liquid metals is a simple and efficient method. However, precise modulation core shell components to regulate microwave absorption performance still needs be further explored. In this study, various types indium/oxide are prepared based on competitive gallium‐indium metals. exhibit superior electromagnetic (EM) wave properties with minimum reflection loss (RL) −40.25 dB at 1.7 mm widest effective band 6.12 GHz 2.1 mm. wave‐absorbing originate from dielectric losses interfacial dipole polarizations. addition, an externally applied magnetic field improves polarization dissipation achieve RL −45.65 2.4 liquid‐metal‐assisted strategies extend variety for applications.

Abstract Electromagnetic interference (EMI) shielding materials with low electromagnetic (EM) waves reflection characteristics are ideal for blocking EM radiation and pollution. Materials reflectivity must be constructed using excellent absorption properties. However, simultaneously possessing both EMI performance remain scarce, consequently, multilayer structures need to developed. Poly(p‐phenylene–2,6–benzobisoxazole) nanofibers (PNF) prepared by deprotonation. PNF combined MXene heterostructure MXene@Ni in‐situ growth; MXene@Ni/PNF acts as an layer while MXene/PNF reflective layer. Finally, (MXene@Ni/PNF)–(MXene/PNF) aerogels layer‐by‐layer freeze‐drying based on the layered modular design concept. Experimental characterizations revealed that enable efficient absorption‐reflection‐reabsorption of waves, effectively eliminating EMI. When mass ratio Ni in is 1:6 fraction 80 wt.%, exhibit (71 dB) a very coefficient (R = 0.10). Finite element simulations verified developed asymmetric structural achieve high characteristics. In addition, display infrared camouflage ability.

Abstract Multifunctional, flexible, and robust thin films capable of operating in demanding harsh temperature environments are crucial for various cutting-edge applications. This study presents a multifunctional Janus film integrating highly-crystalline Ti 3 C 2 T x MXene mechanically-robust carbon nanotube (CNT) through strong hydrogen bonding. The hybrid not only exhibits high electrical conductivity (4250 S cm −1 ), but also demonstrates mechanical strength durability both extremely low environments, showing exceptional resistance to thermal shock. 15 μm thickness reveals remarkable multifunctionality, including efficient electromagnetic shielding effectiveness 72 dB X band frequency range, excellent infrared (IR) capability with an average emissivity 0.09 (a minimal value 0.02), superior camouflage performance over wide range (− 1 300 °C) achieving notable reduction the radiated by 243 °C against background °C, outstanding IR detection characterized 44% increase when exposed 250 W radiation. MXene/CNT offers feasible solution shielding/detection under challenging conditions.

Abstract With the continuous advancement of communication technology, escalating demand for electromagnetic shielding interference (EMI) materials with multifunctional and wideband EMI performance has become urgent. Controlling electrical magnetic components designing material structure have attracted extensive interest, but remain a huge challenge. Herein, we reported alternating composite films composed hollow metal–organic frameworks/layered MXene/nanocellulose (HMN) by vacuum-assisted filtration process. The HMN exhibit excellent effectiveness in GHz frequency (66.8 dB at Ka-band) THz (114.6 0.1–4.0 THz). Besides, also high reflection loss 39.7 0.7 an effective absorption bandwidth up to 2.1 THz. Moreover, show remarkable photothermal conversion performance, which can reach 104.6 °C under 2.0 Sun 235.4 0.8 W cm −2 , respectively. unique micro- macro-structural design structures will absorb more incident waves via interfacial polarization/multiple scattering produce heat energy local surface plasmon resonance effect. These features make film promising candidate advanced devices future 6G protection electronic equipment cold environments.
