摘要
ABSTRACT Multispectral stealth materials that simultaneously suppress radar and infrared (IR) signatures while providing real‐time structural sensing are crucial for next‐generation unmanned aerial vehicles (UAVs), yet remain largely unrealized. Here, we report a lightweight multidimensional MXene/MOF‐derived carbon foam (MMC) that achieves synergistic radar–IR stealth and self‐diagnostic capability. The 0D/2D/3D heterostructure, comprising ZIF‐67 derived Co‐NPs, accordion‐like Ti 3 C 2 T x MXene, and a 3D carbon skeleton, delivers broadband electromagnetic absorption (RL min = −56.02 dB, EAB max = 7.30 GHz) through multi‐path scattering, interfacial polarization, and magnetic–conductive coupling. Simultaneously, MXene's intrinsically low IR emissivity combined with the porous carbon framework yields robust thermal camouflage, maintaining near‐ambient surface temperatures between 25 and 80 °C. Voltage‐driven Joule heating further enables dynamic IR signature modulation. Benefiting from its elastic conductive network, the composite exhibits high piezoresistive sensitivity (1.98 kPa −1 ) for real‐time strain and airflow monitoring, establishing an integrated stealth–sensing platform. This work introduces a multifunctional, ultralight foam that unites adaptive radar/IR stealth with structural health monitoring, providing a promising route toward intelligent UAV skin and advanced multifunctional defense materials.
