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.

用水性丙烯酸树脂和花形 ZnO 构建疏水复合涂层

制备水接触角超过 90 ^∘的疏水涂层具有很高的防水、防污和自清洁性能的潜力。本研究采用花形氧化锌、对环境无害的水性丙烯酸树脂和硬脂酸构建复合疏水涂层。涂层的疏水性通过水接触角法（WCA）测试。复合涂层的WCA可延长至^128∘. 复合疏水涂层表现出良好的防腐和自洁性能。此外，复合疏水涂层在可见光照射下也表现出良好的光催化降解性能，亚甲蓝试验表明了这一点。复合涂层浸泡在 3.5wt.% NaCl溶液具有优异的耐久性。实践证明，所制备的疏水涂层可广泛应用于防腐和自洁领域。
