Roof leakage is a common phenomenon on rainy days and makes residents uncomfortable. Superhydrophobic materials are promising candidates to protect grass houses from rainwater. However, mechanical weakness, chemical corrosion, and UV light sensitivity are the three main challenges restricting these nonwetting materials from wider application in real life. Herein, we developed an inorganic–organic superhydrophobic paint (IOS-PA) for preparing a waterproof grass house. IOS-PA not only showed mechanical robustness and chemical anticorrosion but also displayed self-healing properties, anti-icing properties, and high and low temperature (150 °C and −196 °C) resistance. Photocatalysis was also achieved with IOS-PA, as demonstrated by organic matter (Nile red, methyl blue, and methyl orange) degradation. Moreover, extremely long-term UV resistance, i.e., resistance to UV irradiation (365 nm, 5.0 ± 0.6 mW/cm²) for 100 h and ambient sunlight for 8640 h (1 year), caused the conflicting properties of superhydrophobicity and photocatalysis to coexist in IOS-PA, further accomplishing self-cleaning for the removal of both dirt particles and organic contamination. Specifically, a grass house coated with IOS-PA exhibited favorable waterproof properties, indicating the potential to ensure comfortable living conditions for people living in undeveloped areas, even on rainy days. With a variety of excellent characteristics, IOS-PA, we believe, is advantageous for scalable production and practical application in reality.

屋顶漏水是下雨天的普遍现象，让居民感到不舒服。超疏水材料是保护草屋免受雨水侵袭的有希望的候选材料。然而，机械弱点、化学腐蚀和紫外线敏感性是限制这些非润湿材料在现实生活中更广泛应用的三个主要挑战。在此，我们开发了一种用于制备防水草屋的无机-有机超疏水涂料 (IOS-PA)。IOS-PA 不仅表现出机械坚固性和化学防腐性，而且还表现出自愈性能、防冰性能和耐高温和低温（150°C 和 -196°C）性能。IOS-PA 也实现了光催化，如有机物（尼罗红、甲基蓝和甲基橙）降解所证明的那样。此外，极长的抗紫外线能力，即² ) 100 小时和环境阳光下 8640 小时（1 年），导致 IOS-PA 中超疏水性和光催化的矛盾性质共存，进一步实现了去除污垢颗粒和有机污染物的自清洁。具体而言，涂有 IOS-PA 的草屋表现出良好的防水性能，表明即使在下雨天，也有可能确保居住在未开发地区的人们的舒适生活条件。我们认为，IOS-PA 具有多种优良特性，有利于可扩展的生产和现实中的实际应用。
