Superamphiphobic coatings have been widely used in self-cleaning and antifouling materials because of their unique liquid repellency. In this study, magnetic Fe₃O₄ particles and resin were sprayed to construct hierarchical scales of texture, and 1H,1H,2H,2H-perfluorodecyltriethoxysilane was used to reduce surface free energy, and a biomimetic hair-like composite coating was prepared. The microstructure and chemical composition of the coating was characterized by scanning electron microscopy (SEM) and energy-dispersive spectroscopy (EDS). Both aqueous and oily liquid droplets can retain a perfectly quasispherical shape on the coating surface. The biomimetic hair-like composite coating exhibited superior water-collecting and superamphiphobic properties as well stable resistance against severe temperature, concentrated acidic, alkaline solutions and mechanical damages. This design strategy may provide useful guidelines for the fabrication of large-scale regular superamphiphobic surfaces.

超疏水涂层因其独特的疏液性而被广泛应用于自清洁和防污材料中。在本研究中，磁性 Fe ₃ O ₄喷涂颗粒和树脂以构建纹理层次结构，并使用1H，1H，2H，2H-全氟癸基三乙氧基硅烷降低表面自由能，制备仿生毛发状复合涂层。通过扫描电子显微镜（SEM）和能量色散光谱（EDS）表征涂层的微观结构和化学成分。水性和油性液滴都可以在涂层表面保持完美的准球形。该仿生毛状复合涂层具有优异的集水和超疏水性能，对高温、浓酸、碱溶液和机械损伤具有稳定的抵抗力。这种设计策略可以为制造大规模规则的超疏水表面提供有用的指导。
