Tailored Versatile Janus Fabrics as Breathable, Antibacterial, and Comfortable for Personal Thermal‐Moisture Management

Abstract Textiles capable of passive thermal management offer a sustainable approach to personal comfort and energy conservation. Despite advances in material design, achieving simultaneous thermal‐moisture regulation, durability, and antimicrobial protection remains challenging. Here, a multifunctional metafabric fabricated is presented via in.situ synthesis and dip‐coating, which combines high solar reflectivity (91.2%) and infrared emissivity (96.6%) for efficient radiative cooling. The fabric exhibits exceptional antimicrobial efficacy (>99.5% against Staphylococcus aureus ( S. aureus ) and Escherichia coli ( E. coli )) without compromising thermal performance. Mechanical testing confirms outstanding durability, with minimal mass loss (<2.3%) and stable thermal properties after 120 abrasion cycles. This robust, multifunctional textile provides a practical solution for personal thermal management across diverse environments while mitigating microbial contamination risks.
