Work from the University of Manchester outlines applications for smart surface technology that covers the entire electromagnetic spectrum, including the visible light region. Applications for the new optical devices range from next-generation display devices to dynamic thermal blankets for satellites, as well as multispectral adaptive camouflage.
The tenability of these devices comes from electro-intercalation, a process that in this case involves the interposing of lithium ions between sheets of multilayer graphene (MLG), offering control over electrical, thermal, and magnetic properties.
The device on the left is shown in its discharged state, appearing dark gray in the visible spectrum, in contrast to its charged state on the…
