The accumulation of ice on surfaces will bring safety issues to various human activities. Researchers have been actively developing superhydrophobic (SHS) as good anti-icing materials. However, some limitations, such high cost, complexity preparation, and lack sufficient durability in extreme environments, restrict their practical applications. Inspired by bronchial mucosa cilia structure the lotus leaf structure, we generated ordered magnetic microcilia arrays (MMA) within 1 min a fast controllable microhole assisted magnetic-induced self-growth method. Fluoride-free MMA (SMMA) was prepared impregnating into hexadecyltrimethoxysilane (HDTMS) modified SiO2 solution. SMMA exhibits excellent static performance, which can significantly delay freezing droplets supercooled environments. surface still maintains dynamic performance at −30 °C after 100 times droplet impact. Furthermore, shows for up 2 months low temperatures (−18 °C). Due sensitive response bending properties cilia, also demonstrate outstanding multifunctional manipulation under field. has ability vertically capture release droplets. achieve horizontal transport droplets, mixing microchemical detection, antigravity an 8° inclined array, even complex objects be easily transported. More importantly, mechanical chemical stability. It provides insights preparation integrated using simple green low-cost

Flexible cilia of natural species are well-known for their capabilities to transport objects by collective motions. Therefore, well-ordered, flexible, and stimuli-responsive artificial have been developed render similar functionalities. However, flexibility stimuli-responsiveness a microcilium inherently incompatible with durability/robustness against mechanical damage, limiting the applications only gentle operating conditions. The critical (but long neglected in surface engineering) property hairs is that they rooted under skin, allowing regeneration damaged from undamaged roots (hair follicles). To integrate functionalities hair, we fabrication strategy called stencil-assisted self-alignment iron-laden aerosols produce termed armored regenerable cilia. This contains appropriately packed, magneto-responsive wires within pores. wall pore serves as armor protect bottom part remaining regrow when repeats. such water repellency, object manipulation, impurity removal expected guide design smart surfaces serving real-life applications.

The inefficacy of repelling water droplets laden with macromolecules (complex or diluted polymer solution) is a long-standing shortcoming superhydrophobic surfaces, which severely limits their reliability in practical applications.

Inspired by the "Salvinia effect", a novel method for fabricating magneto-responsive superhydrophobic surface coated with cluster-distributed cilia array (CC-MRSS) was reported. This features magnetically self-assembled nonuniform microcilia and demonstrates exceptional microdroplet hydrophobicity, magnetic-responsive wettability, corrosion resistance. The fabrication process involved mixing polydimethylsiloxane (PDMS) carbonyl iron powders (CIPs), followed dividing mixture into two parts. first part poured 3D-printed female mold to form an elastic substrate hemispherical array. second sprayed onto using air spray method. When external magnetic field applied during curing, dense on hemispheres of substrate. As result, CC-MRSS, two-level composite microstructure, successfully prepared. Contact angle tests showed static contact 157.0° 8 μL water droplet. Multiple samples were tested controllable hydrophobicity varying spraying volume CIP weight fraction. relationship between wettability analyzed, magneto-elastic coupling theory developed explain variation. An optimal parameter scheme proposed achieve maximum range. optimized CC-MRSS can switch low-hydrophobic state (118.2°) (151.5°) upon switching, high repeatability over ten cycles. Notably, Salvinia-inspired maintains film underwater, just like Salvinia leaf, reducing surface-solution offering superior resistance other ciliary materials.
