Polyester fabric was successively immersed in aqueous polyurethane adhesive solution and the ethanol solution composed of nano silica modified by vinyl triethoxysilane, 2-methacryloyloxyethyl trimethyl ammonium chloride, polyethylene glycol dimethacrylate, trimethylolpropane triacrylate and 2-hydroxy-2-methylpropiophenone. After UV curing, the inorganic and organic composite superhydrophilic coating on polyester fabric was obtained. FT-IR, SEM and contact angle test confirmed the formation of the superhydrophilic coating on the surface of the fabric. The minimum time for water droplets to fully spread on the surface of the superhydrophilic polyester fabric was only 301 ms. The superhydrophilic polyester fabric could be used for oil-water separation. The separation efficiency reached 99.4% and maintained more than 98% even after 50 separation cycles.
