  • Patent number: 11767455
    Abstract: A superhydrophobic hemispherical array which can realize droplet pancake bouncing phenomenon is provided. The superhydrophobic hemispherical array shows an arc-shape structure which is narrow at the top and wide at the bottom, where a is the angle that substrate-gas interface goes across the gas and reaches substrate-hemisphere interface, d refers to the diameter of the contact area between hemispherical structure and substrate, s represents the space between two adjoining hemispheres, h denotes the vertical height from the top of hemisphere to substrate surface, and 70°?a?90°, 900 ?m?d ?1700 ?m, s?550 ?m, 600 ?m?h?1100 ?m, respectively. The superhydrophobic hemispherical array has a water contact angle larger than 150° and roll-off angle lower than 10°.

  • Patent number: 11104043
    Abstract: A thermal extrusion method to fabricate large-dimension superhydrophobic cylinder pillar arrays with droplet pancake bouncing phenomenon. Preparing thermal extrusion mold: the through-hole arrays with 0.8˜1.25 mm diameter, 0.25 mm interval space and 0.6˜1.0 mm height are first obtained on metals, and are then polished, rinsed and dried. Thermal extrusion: polymer materials are first thermally extruded on the obtained mold and cooled to room temperature. Demold: excess polymer materials flowing from the through hole are cut off and then the polymer cylinder pillar arrays are lifted off from the mold. Superhydrophobic treatment: the whole polymer sample is treated using mixed liquid spray consisting of titanium oxide nanoparticles dispersed in fluoroalkylsilane ethanol solution, and the superhydrophobic cylinder pillar arrays are obtained.
