Abstract

The fabrication of hydrophobic coatings whose water contact angle is over 90∘ has high potential to induce waterproof, anti-fouling, and self-cleaning properties. In this research, a composite hydrophobic coating was constructed with flower-shaped ZnO, waterborne acrylic resin that is harmless to the environment and stearic acid. The hydrophobicity of the coating is tested by means of water contact angle method (WCA). The WCA of the composite coating can be extended up to 128∘. The composite hydrophobic coating displayed good performances of anti-corrosion and self-cleaning. In addition, the composite hydrophobic coatings also showed good photo-catalytic degradation property under visible light irradiation, which was shown by means of the methylene blue test. The composite coating soaked in 3.5wt.% NaCl solution had excellent durability. It is proved that such produced hydrophobic coatings can be widely applied to the field of anti-corrosion and self-cleaning.
