• • Achieved EMI shielding effectiveness of 79.23 dB with a reflection coefficient of 0.03 at 4.40 mm thickness, enabling absorption-dominated shielding (SE_R < 3.01 dB) critical for reducing secondary electromagnetic pollution in sensitive electronic environments.
• • Maintained effective absorption-dominated shielding at a reduced thickness of 1.40 mm, demonstrating the feasibility of thin, lightweight stealth materials for portable and wearable applications.
• • Demonstrated high durability with stable EMI shielding performance under ultrasonic, compression, and bending tests, ensuring reliability in dynamic operational conditions such as flexible electronics and protective gear.
• • Integrated flame-retardant thermoplastic polyurethane (TPU) and melamine foam (MF) substrates, providing self-extinguishing properties essential for fire safety in military and aerospace applications.
