Research on the Application of Microencapsulated Phase Change Materials to Thermal Infrared Camouflage

In order to reduce the difference in radiant intensity between background and military targets, such as road or surface of building decorated with concrete, based on the law of Stephen-Boltzmann, the influence of emissivity or temperature on radiant energy was analyzed, phase change materials (PCMs) were employed in adjusting or controlling radiant energy from military targets from the point of temperature, then the low-detective probability of the target was achieved.
