and a low emissivity of 0.17. At an ambient temperature of 200 °C, its radiant temperature is merely 40.7 °C, outperforming pure PI, TM film and commercial fabrics in terms of stealth performance. The incorporation of TA further enhances oxidation stability for PI/SA/TM, retaining excellent emissivity (0.24) even after 15 days of humid heat aging. This work provides new technical support for designing advanced functional integrated infrared stealth materials.
