Overcoming ice accretion on external aircraft wing surfaces plays a crucial role in aviation, and developing environmentally friendly passive anti-icing is considered to be promising strategy. Superhydrophobic (SHSs) have attracted increasing attention due their potential advantages of keeping the airframe dry without causing additional aerodynamic losses. However, performances SHSs reported date varied lot under different icing test conditions. Therefore, systematic investigation necessary...
In this work, we investigate the freezing behavior and ice adhesion properties of sessile drops on micropillared superhydrophobic surfaces (SHSs) with various sizes, which are practical importance for anti/deicing. First all, it is demonstrated that recalescence related only to supercooling degree but not geometrical parameters micropillars. The time first increases then decreases area fraction SHSs, demonstrates nonmonotonic dependence icing fraction. Moreover, influence micropillars...
Superhydrophobic surfaces have been widely studied due to their potential applications in aerospace fields. However, superhydrophobic with excellent water-repellent, anti-icing, and icephobic performances at low temperatures rarely reported. Herein, heating capability were prepared by etching square micropillar arrays on the surface of multiwalled carbon nanotube (MWCNT)/poly(dimethylsiloxane) (PDMS) films. The fabricated has triple icephobicity, which can be activated even temperatures....
Reducing unfavorable ice accretion on surfaces exposed in cold environment requires effective passive anti-icing/deicing techniques. Icephobic are widely applied various infrastructures due to their low adhesion strength and flexibility, whereas poor mechanical durability, common liquid infusion, weak resistance contamination, bonding substrates the major remaining challenges. According fracture mechanics of layer, initiating cracks at ice-solid interfaces via proper design internal...
Liquid fluidity is a most key prerequisite for broad range of technologies, from energy, fluid machineries, microfluidic devices, water, and oil transportation to bio-deliveries. While thermodynamics, the liquid gradually diminishes as temperature decreases until completely solidified below icing points. Here, self-driven droplet motions are discovered demonstrated occurring in environments accelerating with both moving distances volumes. The motions, including self-depinning continuous...
