Recently, there has been increasing interest in developing artificial superhydrophobic surfaces, especially in the field of self-cleaning application. However, the poor robustness and high-cost preparation of these surfaces have always been some issues for their industrial development. Herein, we describe an environmentally friendly way to prepare stable, robust, and transparent superhydrophobic coatings through the deposition of a rough substructure of TiO₂ film followed by chemical modification using octadecyltrichlorosilane (OTS), a fluorine-free organic silane. The as-prepared coatings exhibited a great superhydrophobic property and ultralow adhesion (with a static water contact angle of 158 ± 2° and sliding angle of 4 ± 1°). It was found that the superhydrophobic coatings can still maintain good performance after UV irradiation, chemical immersion, and physical abrasion. More importantly, the coated surfaces showed an excellent self-cleaning ability against dirt particles after rinsed with water droplets.

最近，人们对开发人造超疏水表面的兴趣日益增加，特别是在自清洁应用领域。但是，这些表面的坚固性差和制备成本高一直是其工业发展的问题。在这里，我们描述了一种环保的方法，可通过沉积TiO ₂的粗糙亚结构来制备稳定，坚固和透明的超疏水涂层薄膜，然后使用十八烷基三氯硅烷（OTS）（一种无氟有机硅烷）进行化学修饰。所制备的涂料显示出极好的超疏水性和超低的附着力（静态水接触角为158±2°，滑动角为4±1°）。已经发现，超疏水性涂层在紫外线照射，化学浸渍和物理磨损后仍能保持良好的性能。更重要的是，在用水滴冲洗后，涂层表面对污垢颗粒具有出色的自清洁能力。
