Abstract:
Icing on the surface of aircraft will not only aggravate its quality and affect flight control， but even cause safety accidents， which is one of the important factors restricting all-weather flight. Bio-inspired anti-icing surfaces have gained great attention recently due to their low-hysteresis， non-stick properties， slow nucleation rate and low ice adhesion strength. These bio-inspired anti-icing surfaces， such as superhydrophobic surfaces， slippery liquid-infused porous surfaces and quasi-liquid film surfaces， have realized excellent anti-icing performance at various stages of icing. However， for harsh environment， there are still many problems and challenges. From the perspective of bio-inspiration， the mechanism of icing nucleation， liquid bounce and ice adhesion has been reviewed together with the application progress and bottleneck issues about anti-icing in view of the process of icing. Subsequently， the reliability and development prospect of active， passive and active-passive integrated anti-icing technology are discussed， respectively.
