Title:A design of fluorine-free coating for durable amphiphobic fabric

The potential risk of perfluorinated compounds (PFCs) has significantly restricted the commercial application of amphiphobic surfaces in the fabrication of water- and oil- repellent fabrics. In this work, we present a novel fluorine-free amphiphobic fabric, featuring a hierarchical surface architecture comprising silica gel particles and a specially designed polymer coating. The obtained fabric showed a water contact angle of 156° and an olive oil contact angle of 125°. Furthermore, the fabric maintained a water contact angle above 150° after rigorous durability assessment including 1500 abrasion cycles and 12-h chemical corrosion test, demonstrating high robustness of the coating. Notably, the fabric exhibited comparable repellency to low-surface-tension liquids with the commercial fluorinated counterparts. This environmentally benign alternative, combining superior amphiphobicity with exceptional durability, presents a promising solution for diverse practical applications in protective textiles and outdoor apparels.
