Multifunctional flexible conductive materials have attracted significant attention as next-generation portablewearable electronics. However, designing robust electronics fabrics with high-performance electromagnetic interference(EMI) shielding and reliable use in all-weather environments remains a challenge. Herein, a practical and optimizedmethodology was provided to achieve surface metallization of insulating fabrics for conductive devices. The Ag seeds weresuccessfully embedded on the surface of viscose nonwovens as catalytic centers, and ammonia-free silver plating was carriedout at room temperature. Subsequently, the Ag-wrapped fabric was impregnated with 1-octadecanethiol so that the surface ofthe obtained fabric showed super-hydrophobicity and water contact angle can reach 152.3 °. The Ag/viscose exhibitsultrahigh conductivity (up to 538 S/cm) and the EMI shielding effectiveness (SE) reaches as high as 94.1 dB in the range of1-18 GHz. The obtained Ag/viscose possesses outstanding waterproof, strong mechanical durability, excellent Joule heatingeffect and antibacterial, which can be potentially applied for multifunctional wearable electronics and smart clothing.
