Опубликована: Янв. 7, 2025

Ice accretion caused by freezing rain or snowstorms is a common phenomenon in cold climates that seriously threatens the safety and reliability of telecommunication lines other overhead networks. Various anti-icing strategies have been demonstrated through surface engineering to delay ice formation. However, existing surfaces still encounter several challenges; for example, are prone ice-pinning formation due impact supercooled droplets, which leads loss effectiveness. In this study, mushroom-like cross-scale (MCS) with extreme pressure resistance superior anti-ice-pinning property was reported. Specifically, designed MCS, featuring multiscale microfeatures, re-entrant structure, heterogeneous sidewalls, nanoscale particles, exhibits excellent properties. determined occur process involving liquid penetration, condensation, icing, frost filling. By establishing an anti-ice -pinning model bubble column model, relationship between structural characteristics performance clarified. The MCS demonstrates static repellency (contact angle >167°) robust dynamic (water Weber number ≥300). Furthermore, it ultralow adhesion strength 0.46 kPa. Notably, remains below 5 kPa even after 15 deicing cycles. mechanism icephobicity induced micromorphologies provide valuable insights effective prospects line areas field information communication technology.

Frost formation is a normal phase transition phenomenon in cold climates, while it usually brings certain troubles to human lives and production. Therefore, of great significance develop frost resistant materials key technologies. Here, salt-philic superhydrophobic surface designed on PDMS substrate by femtosecond laser direct writing technology combination with salt–ethanol–water mixtures droplet treatment. The laser-treated embedded salt (LTP-S) exhibits superhydrophobicity, which alone property that can resist the enables self-cleaning effect. Meanwhile, coating further enhances resistance reducing freezing point temperature. LTP-S revealed perform well frosting-defrosting cycles, washing resistance, chemical corrosion heating long-term air exposure tests as highly efficient stable anti-frosting surface. This work demonstrates facile strategy fabricate for anti-frosting.

A method of femtosecond laser multi-pulse grid-like point etching (MP-GPE) was used to prepare glass fiber reinforced plastics with superhydrophobic properties. This article investigates the influence trend single-pulse energy (5-35 μJ) and pulse number (20-100) on morphology surface concave holes, including depth width. Different combinations process parameters have a modulating effect size hole structure ablation plastics. At 25 μJ 60 numbers, holes increases maximum approximately 63 μm, width upper is 33 μm. Under these conditions, water contact angle 160.6° obtained, which consistent theoretical calculation results 161.6°. very promising for power industry use this material in low-temperature, drag-reducing environments.
