High-performance wearable bimetallic nanowire-assisted composite foams for efficient electromagnetic interference shielding, infrared stealth, and piezoresistive sensing

With the accelerated development of modern detection and communication technology, the multifunctional wearable materials with excellent electromagnetic interference (EMI) shielding, infrared stealth, and human monitoring for improving military combat capability have received extensive attention. In this work, the lightweight melamine foam (MF)@silver nanowires (AgNWs)-iron nanowires (FeNWs) (AgFe-MF) was fabricated by a vacuum-assisted dip-coating method. Due to the porous structure and synergistic electrical and magnetic losses, this lightweight (0.115 g/cm3) composite foam with an ultra-low filler content (0.62 vol.
