Manipulating metals for adaptive thermal camouflage.Many species in nature have evolved remarkable strategies to visually adapt to the surroundings for the purpose of protection and predation.  Here, we report adaptive thermal camouflage devices by bridging the optical and radiative properties of nanoscopic platinum (Pt) films and silver (Ag) electrodeposited Pt films.  Furthermore, these devices can be easily multiplexed, enlarged, applied to rough and flexible substrates, or colored, demonstrating their multiple adaptive camouflaging capabilities.  We believe that this technology will be advantageous not only in various adaptive camouflage platforms but also in many thermal radiation management-related technologies.
