Multifunctional Hydrogen-Bond-Cross-Linked PDMS/MXene/Fe₃O₄–NH₂/Cotton Fabric for Male Reproductive Electromagnetic Protection

With the increasing exposure to electromagnetic radiation (EMR) and its detrimental effects on male reproductive health, there is an urgent demand for advanced protective materials. This study presents a multifunctional hydrogen-bond-cross-linked PDMS/MXene/Fe 3 O 4 –NH 2 /cotton fabric (PMFC) designed for male reproductive electromagnetic protection. The composite fabric integrates MXene nanosheets and Fe 3 O 4 –NH 2 nanoparticles via layer-by-layer assembly, enhanced by hydrogen bonding and hydrophobic PDMS coating. Remarkably, PMFC achieves an exceptional electromagnetic interference shielding efficiency of 56.4 dB at 0.35 mm thickness, outperforming existing materials. Its ultralow infrared emissivity (0.33) enables effective thermal stealth, while programmable Joule heating (up to 109.9 °C at 4.5 V) ensures adaptability to diverse environments. Furthermore, PMFC retains cotton’s inherent breathability, moisture permeability, and softness, coupled with superhydrophobicity (water contact angle: 147.7°) and mechanical durability. This work not only addresses the critical challenge of electromagnetic protection for male reproductive health but also pioneers a versatile textile platform for multifunctional wearable applications.
