Abstract: Structural colors based on natural and artificial microstructures show promising light manipulation. As atomically thick building blocks, Ti 3 C 2 T x sheets have been successfully assembled into the ultrathin, flexible, arbitrarily cuttable, large-size structural colors by the simple and low-cost spray methods based on the lossy thin-film interference. By ordered stacking atomically thick Ti 3 C 2 T x layer by layer at well-organized low–surface tension semidry assemble state, rich colors from yellow to gray with the thickness from ∼22 to ∼154 nanometers of uniform Ti 3 C 2 T x colors are obtained, having the thinnest framework among solution-processed flexible structural colors with similar optical performance. Low-infrared emissivity from room to 300°C temperature and region-selective patterns make highly information-fused and complex visible-infrared (VIS-IR) Ti 3 C 2 T x colors camouflage. Without conventional dielectric layer between Ti 3 C 2 T x and substrate, automated spraying system can produce meter-scale films that can be cut and sewn into VIS-IR concealment “camouflage cloaks” easily, promising ultrathin multifunctional information systems and beyond.
