Many species have naturally evolved remarkable strategies to visually adapt to their environments for protection and predation. Researchers have studied adaptive camouflaging in the infrared (IR) spectrum, although the method is highly challenging to develop in the lab. In a new report now published on Science Advances, Mingyang Li and a research team at the National University of Defense Technology in China, developed adaptive thermal camouflage devices that bridged the optical and radiative properties of nanoscopic platinum (Pt) and silver (Ag) electro-deposited Pt films. The metal-based devices maintained large, uniform, and consistent IR tunabilities in the mid-wave IR (MWIR) and long-wave IR (LWIR) atmospheric transmission windows (ATWs). The team multiplexed and enlarged the devices, allowing flexibility for camouflaging capabilities. The technology is advantageous across a variety of camouflage platforms and in many thermal radiation management technologies.
