Abstract Infrared and radar detectors posed substantial challenges to weapon equipment personnel due their continuous surveillance reconnaissance capabilities. Traditional single‐band stealth devices are insufficient for dual‐band detection in both infrared microwave bands. To overcome this limitation, a gradient‐structured MXene/reduced graphene oxide (rGO) composite aerogel (GMXrGA) is fabricated through two‐step bidirectional freeze casting process, followed by freeze‐drying thermal annealing. GMXrGA exhibits distinct three‐layered structure, with each layer playing crucial role absorption. This deliberate design amplifies the efficiency of absorption material's effectiveness dynamic camouflage. displays an ultralow density 5.2 mg∙cm −3 demonstrates exceptional resistance compression, enduring 200 cycles at maximum strain 80%. Moreover, it shows superior performance, minimum reflection loss ( RL min ) –60.1 dB broad effective bandwidth EAB 14.1 GHz (3.9–18.0 GHz). Additionally, low conductivity (≈26 mW∙m −1 ∙K camouflage capabilities within temperature range 50–120 °C, achieving rapid concealment 30 s. Consequently, they hold great potential diverse applications, including intelligent buildings, wearable electronics, equipment.
