Abstract A novel robust, anti-icing, self-cleaning superhydrophobic coating was prepared via a simple, environmentally, friendly and efficient strategy which bond nanoparticles SiO2 to the polyurethane surface under UV-curing. By controlling the content of nano-silica, a superhydrophobic coating with sliding angle (SA) of 2° and water contact angle (WCA) of 165° was constructed. The coating can be widely applied to various substrates with excellent anti-fouling properties and acid/alkali resistance. Meanwhile, the surface of coating is robust, can maintain superhydrophobic after 750 cycles of friction. In addition, the coating has a good anti-icing property which maintains excellent superhydrophobic after being placed at −10 °C for 100 h. Hence, the coating could be widely used on the surface of transmission lines and wind turbines. Highlights A novel UV-curable polyurethane coating with water contact angle of 110° is prepared. The superhydrophobic coating shows excellent mechanical properties and can withstand 750 cycles of friction. The superhydrophobic coating shows excellent anti-icing property at −10 °C.
