A Multi-Scale Cross-Band Defense System Integrating Decoupled Visible, Dynamic Infrared Camouflage and Electromagnetic Shielding

Abstract Cross-band camouflage technology is a critical necessity, enabling personnel and equipment to evade detection across evolving surveillance systems, thereby enhancing survivability and mission success. Herein, this work develops a layer-structured composite system based on carbon nanotube (CNT) film comprising ionic liquid (IL) interlayer for infrared (IR) modulation and surface-engineered Cu 2 O nanoparticles for visible camouflage. The CNT/IL/CNT architecture enables reversible IR emissivity switching (Δε≈0.55) through electrically driven ion intercalation/deintercalation within 2 s, while spray-coated Cu 2 O nanoparticles (100 ~ 400 nm diameter) on the top CNT film layer generate rich structure…
