With the continuous development of infrared detection equipment, higher requirements are put forward for the survivability of various weapons and equipment. Infrared stealth technology can reduce or control the infrared radiation of the target, shorten the distance and reduce the probability of being discovered, and improve the survivability of the target. In recent years, the rapid development of electrochromic technology provides a new idea for the regulation of infrared emissivity. Under the action of low electric field, electrochromic materials can realize reversible and stable regulation of optical properties (transmittance, absorptivity, reflectivity, etc.) in a wide spectral range (visible light and near, middle and far infrared), and have the advantages of low energy consumption, rapid response, stable cycle performance, etc., and the available infrared electrochromic materials system is rich. Therefore, electrochromic technology can be applied to dynamic infrared stealth, which can adapt the target to the change of environmental background, and has important application prospects in infrared stealth and camouflage.
