Abstract: Abstract Superamphiphobic and flame-retardant fabrics offer effective protection for firefighters and industrial workers operating under hazardous conditions. However, limitations in deformation resistance, wear comfort, and environmental adaptability hinder their practical applications. Here, a monolithic hierarchical macro-/micro-/nanostructure is constructed to achieve durable repellency against water and oils, even under significant deformations. This coating integrates fluorinated nanoparticles, flame retardant microparticles, and a cross-linking adhesive. Hydrogen bonding and the adhesive define the coating’s morphology, robustness, and adaptability. The coated surface exhibits an ultralow water adhesion force (0.002 mN) and excellent anti-fouling performance against extreme temperatures (100 °C, −196 °C) and corrosive liquids, including aqua regia and concentrated H2SO4. Upon fire exposure, the coating enables self-extinguishing behavior on cotton fabrics. The coated fabrics also demonstrate remarkable mechanical and UV resistance while preserving wear comfort. Overall, we achieve a balance between desirable properties and wear comfort in superamphiphobic, flame-retardant fabrics, enabling protective clothing applications previously unattainable.
