• • CNT fibers achieve a specific tensile strength of 25.3 cN/dtex and electrical conductivity of 3634.2 ± 114.0 S/cm, enabling robust, conductive fabrics that outperform many metallic alternatives on a weight-adjusted basis.
• • Single-layer CNT fabric provides 66.8 dB EMI SE, while multilayer stacks reach 111 dB, exceeding the 90.49 dB reported for MXene-incorporated sponges and satisfying stringent aerospace and defense shielding requirements (typically >60 dB).
• • The fabric maintains an ultralow density of 0.2 g/cm³, reducing the shielding layer mass in coaxial cables by 32.1% compared to copper, directly addressing weight-critical applications in aerospace and portable electronics.
• • Durability tests confirm resistance to repeated bending and washing, with no reported degradation in shielding performance, indicating suitability for wearable and machine-washable electronics where mechanical robustness is essential.
