Wind turbine blades are often covered with ice and snow, which inevitably reduces their power generation efficiency lifetime. Recently, a superhydrophobic surface has attracted widespread attention due to its potential values in anti-icing/deicing. However, the can easily transition from Cassie-Baxter Wenzel at low temperature, limiting wide applications. Herein, inspired by excellent water resistance cold tolerance of Trifolium repens L. endowed micronano structure energy, fresh was prepared combining femtosecond laser processing technology boiling treatment method. The icephobic aluminum alloy (ISAl) mainly consists periodic microcrater array, nonuniform microclusters, irregular nanosheets. This three-scale greatly promotes stability state. critical Laplace pressure ISAl is up 1437 Pa, apparent contact angle (CA) higher than 150° 0 °C. Those two factors contribute anti-icing deicing performances. results show that static icing delay time reaches 2577 s, adhesion strength only 1.60 kPa. Furthermore, abilities proposed were examined under environment temperature high relative humidity demonstrate effectiveness. dynamic extreme environments 5 h, quickly fall speed 34 r/min when it horizontal rotational motion. Finally, reusability mechanical durability, still being less 6 kPa CA greater after 15 cycles icing-deicing tests. would offer promising strategy for efficient wind blades.

Flexible Mushroom-Like Cross-Scale Surface with Extreme Pressure Resistance for Telecommunication Lines Anti-Icing/Deicing

ACS Applied Materials & Interfaces, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 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.
