Ice accumulation and moisture condensation pose significant challenges to the longevity and performance of modern architectural materials. Superhydrophobic anti-icing coatings often suffer mechanical and chemical degradation, particularly in outdoor settings subject to heavy rain or impact. Additionally, most existing coatings are airtight, leading to humidity accumulation and potential substrate deterioration, especially in cement-based materials. To address these challenges, we developed a nonfluorinated, breathable superhydrophobic coating by spraying a PDMS-IPDI-TFB supramolecular network (PIT) mixed with polydopamine nanoparticles (PDA NPs). The optimized superhydrophobic coating (PSC-40) exhibits high breathability, prevents blistering or cracking, and demonstrates exceptional mechanical and chemical durability. Remarkably, it withstands high-speed water jet impacts (
