Inspired by the natural superhydrophobic surfaces with various colors such as the lotus leaves and the wings of butterflies, we report a one‐step method to fabricate superhydrophobic coatings by the combination of kaolin, acrylic color and organosiloxanes. The coatings were characterized using X‐ray photoelectron spectroscopy, scanning electron microscopy, and other analytical techniques. Different from the previously reported method, kaolin particles were introduced to generate rough hierarchical structures on the coating surface, followed by acrylic color decoration and organosiloxanes modification. The colorful superhydrophobic coatings can be constructed in various substrates, such as glass slide, filter paper, and fabric. Furthermore, the obtained coating maintained excellent mechanical durability, chemical stability, and the high‐efficiency of oil–water separation. All of the colorful coatings showed superhydrophobicity in air, and they retained water repellency even after exposed to ultraviolet or under harsh conditions. The results also indicated that the as‐prepared coatings possessed outstanding fungi‐resistance. The colorful superhydrophobic fabric can be used to separate oil/water mixtures, and the separation efficiencies are as high as 95%. We envision that the colorful superhydrophobic coatings with durability and chemical stability may be useful in various fields, such as house decoration, paint coating, antimicrobial material and oil/water separation.

基于高岭土的具有耐久性和化学稳定性的彩色超疏水材料

受荷叶和蝴蝶翅膀等各种颜色的天然超疏水表面的启发，我们报告了一种通过高岭土，丙烯酸颜料和有机硅氧烷的组合制备超疏水涂料的一步方法。使用X射线光电子能谱，扫描电子显微镜和其他分析技术对涂层进行了表征。与以前报道的方法不同，引入了高岭土颗粒以在涂层表面产生粗糙的分层结构，然后进行丙烯酸颜色装饰和有机硅氧烷改性。可以在各种基材（例如载玻片，滤纸和织物）中构建彩色的超疏水涂层。此外，所获得的涂层保持了优异的机械耐久性，化学稳定性，以及高效的油水分离。所有的彩色涂料在空气中都表现出超疏水性，即使暴露在紫外线下或在苛刻的条件下，它们仍具有拒水性。结果还表明，所制备的包衣具有优异的抗真菌性。该彩色超疏水织物可用于分离油/水混合物，分离效率高达95％。我们预想，具有耐久性和化学稳定性的彩色超疏水涂料可用于各种领域，例如房屋装修，油漆涂料，抗菌材料和油/水分离。结果还表明，所制备的包衣具有优异的抗真菌性。该彩色超疏水织物可用于分离油/水混合物，分离效率高达95％。我们预想，具有耐久性和化学稳定性的彩色超疏水涂料可用于各种领域，例如房屋装修，油漆涂料，抗菌材料和油/水分离。结果还表明，所制备的包衣具有优异的抗真菌性。该彩色超疏水织物可用于分离油/水混合物，分离效率高达95％。我们预想，具有耐久性和化学稳定性的彩色超疏水涂料可用于各种领域，例如房屋装修，油漆涂料，抗菌材料和油/水分离。
