Abstract:Superhydrophobic coatings have excellent application prospects in the field of aircraft anti-icing due to their unique properties. The aim of this paper is to develop a superhydrophobic coating with good corrosion resistance and anti-deicing properties. Hydrophilic silica nanoparticles were prepared using ethyl orthosilicate and hydrophobically modified by poly(trifluoropropylmethylsiloxane). Subsequently, the hydrophobic nanoparticles were combined with fluorosilicone resin to prepare a superhydrophobic coating with a water contact angle of 158.6°, also showed good hydrophobicity for different liquids. After the sandpaper abrasion test, the water contact angle remained at 148.5° after 50 cycles of abrasion. The coating also shows excellent delayed icing and de-icing properties. At low temperatures of ?10°C and ?15°C, the freezing time of water droplets on the coated surface was extended by 205% and 800%, respectively. The ice adhesion of the coated tinplate sheet was reduced by 91.8% compared to the uncoated sheet.
