• • The multilayer composite achieves IR emissivity tunable between 0.30 and 0.43, enabling effective IR camouflage across diverse thermal backgrounds; this range is critical for matching ambient thermal signatures and reducing detectability by IR imagers.
• • At an 80 °C heat source, the composite reduces IR radiation intensity by 40%, demonstrating the synergistic effect of low emissivity and thermal insulation; this performance is vital for suppressing thermal contrast in hot equipment and vehicles.
• • The composite maintains EMI shielding and IR/visible camouflage functionality after exposure to strong acid, strong alkali, saline, and organic media, indicating robust environmental durability essential for long-term deployment in marine, arid, and industrial environments.
• • The integration of a flexible ANF aerogel layer provides mechanical flexibility and lightweight characteristics, addressing the practical need for conformable camouflage materials on curved surfaces without sacrificing performance.
