Multi-Scale Superhydrophobic Anti-Icing Coating for Wind Turbine Blades

As a surface functional material, super-hydrophobic coating has great application potential in wind turbine blade anti-icing, self-cleaning and drag reduction. In this study, ZnO SiO2 multi-scale superhydrophobic coatings with mechanical flexibility were prepared by embedding modified nanoparticles PDMS. The higher static water contact angle (CA is 153°) lower rolling (SA 3.3°), showing excellent super-hydrophobicity. Because of its ability micro-nano structure, the good anti-icing ability. Under conditions ?10°C 60% relative humidity, can delay freezing time 1511S, which 10.7 times slower than normal time. More importantly, due to properties provided synergistic effect particles, durability. After 10 wear tests, still as high 141° 6.8°. This research provides theoretical reference for preparation mechanically stable simple process, well basic on behavior coating.
