In this paper, periodic nanostructure material is proposed to suppress the infrared radiation characteristic of target with higher surface temperature. Periodic nanostructure material has the properties of low emissivity within the 8~14μm band and high transmission In the working condition the thermal energy of the target can be released by using periodic nanostructure material. Physical vapor deposition method is used to fabricate periodic nanostructure materials on the surface of SiC. The emission rate test shows that periodic nanostructure material can effectively suppress infrared radiation within the 8~14μm band and don’t change the radiation outside the 8~14μm band. In the further application of the experiment, fabricate periodic nanostructure on the surface of an ordinary cloth material. Through the experiment, which verify the effect of the infrared suppression of periodic nanostructure material , show that when the actual temperature of the cloth surface is 100℃, the infrared radiation temperature is 40℃.
