Abstract: The traditional camouflage infrared stealthy coating hits the target by controlling the emissivity and deform disguise,then the stealthy efficiency will be low when the target temperature is obviously different from the environment.In order to enhance the infrared stealthy efficiency,the idea of phase changed temperaturecontrolling complex coating design is suggested in this paper.The shortcomings of the traditional stealthy coating by means of low emissivity or infrared distortion is discussed.The idea that the thermal infrared composite coating can not only adapt to single or intricate backgrounds but also withstand different bands thermal imaging system is put forward.From the aspect of structure,function and feasibility of the coating.It shows good temperature reduction and control function,and it is favorable for achieving infrared blending.
