A novel coating for IR/thermal camouflage that can be tuned to any visible color. Background: Security and defense applications are key to international competition. Current thermal camouflage coatings create a metallic grey color that stands out in most natural environments. Technology Overview: This University at Buffalo invention provides multiple layers of Ag-SiO2 nanocomposite films stacked to construct a graded nanomaterial ("GNM") film on a substrate (e.g., glass, polymer, fabric, etc.). The mixture ratio of Ag-SiO2 may be tuned to control the effective refractive index of the film. By controlling the parameters of the film, such as the number of layers and the total thickness of the GNM, one can obtain different colors. The thermal emission of such films is weak. http://buffalo.technologypublisher.com/files/sites/7439_image_a.png Advantages: The color of camouflage can be tuned to any color in the visible spectrum. Applications: Allows painted equipment to mask themselves against their background while also being masked to thermal readers. Intellectual Property Summary: US Provisional Patent Application 63/253,086 filed 10/6/2021. Stage of Development: TRL 6 Licensing Status: Available for licensing or collaboration.
