Infrared stealth technology, as a military anti-reconnaissance technology, achieves low detectability of targets, primarily by suppressing thermal radiation of the targets in the infrared atmospheric window bands (3-5 μm and 8-14 μm). At present, the stealth of infrared detection is mainly realized by reducing or changing the infrared radiation characteristics of a target through cooling, shielding, stealth coating and other means, wherein the coating of a low-emissivity material on the surface of the target is most widely applied. However, the low-emissivity infrared stealth paint has a series of problems of heat accumulation, limited frequency band range, short service life and the like, so that the exploration and development of high-performance infrared stealth materials and technologies are urgent.
