Superamphiphobic and flame-resistant cotton fabrics for protective clothing

Superamphiphobic and flame-retardant finishing of cotton fabric can significantly improve its protective properties to expand applications, such as clothing. However, creating materials is still a challenging issue. Herein, we present facile strategy fabricate superamphiphobic (SFC) via step-by-step dip-coating spraying technology. Ammonium polyphosphate (APP) endows excellent flame retardancy. The robust coating formed by the polymerization product ethyl 2-cyanoacrylate 1H,1H,2H,2H-perfluorooctyl trichlorosilane (FOCS) not only protect APP from being damaged but also trap air form "air plastron", which makes SFC have antifouling, chemical repellence self-cleaning. resulting exhibited superamphiphobicity retardancy with water contact angle 161°, oil 158° LOI 30%. After UV irradiation, mechanical damage, 180 °C oven heating ultrasonic washing, it maintains hydrophobicity without loss This study expands potential applications provides feasible technologies for improving overall efficiency cotton.
