Artificial chameleon skin that controls spectral radiation: Development of Chameleon Cool Coating (C3)

Abstract Chameleons have a diagnostic thermal protection that enables them to live under various conditions. Our developed special radiative control therefore is inspired by the chameleon thermal protection ability by imitating its two superposed layers as two pigment particles in one coating layer....
