Durable Super-repellent Surfaces: From Solid–Liquid Interaction to Applications

Abstract: Conspectus A super-repellent surface is a type of liquid-repellency material that allows for various liquid drops to bead up, roll off, or even bounce back. Known for its ability to remain dry, perform self-cleaning, and have a low adhesion, a super-repellent surface presents great advantages in a number of applications. These include antifogging, anti-icing, oil/water separation, and fluid drag reduction. To fend off the liquids or drops, super-repellent surfaces combine the merits of surface chemistry and ph… Show more

“…Further, the reentrant geometries are also known to suffer from mechanical instability. 135,136 In this section, we lay special emphasis on the use of various chemistries for the independent generation of both the (a) appropriate topography and (b) surface chemistry to obtain robust superamphiphobicity.…”

“…After degasification, the suspension was poured into a reservoir and then flowed across a laboratory-made tube-in-orifice spinneret (inner and outer diameters of 1.3 and 2.5 mm, respectively) under a nitrogen (N 2 ) pressure of 0.05 MPa. Deionized water was used as the internal coagulant applied at different bore liquid flow rates (30,40,50, and 60 mL•min −1 ). The external coagulants were the mixtures of tap water and ethanol with different ethanol volumes (0, 10, 20, 30, 60, and 90 vol %).…”

“…The device surface with varying wettability exhibits different contact angles (CAs) to the liquids, with CA > 90° (or < 90°) for low (or high) surface energy as a hydrophobic (or hydrophilic) state. [77,78] The smooth surface with an intrinsic hydrophobic or…”

“…The device surface with varying wettability exhibits different contact angles (CAs) to the liquids, with CA > 90° (or < 90°) for low (or high) surface energy as a hydrophobic (or hydrophilic) state. [ 77,78 ] The smooth surface with an intrinsic hydrophobic or hydrophilic property can be adjusted by the surface functional groups. The bioinspiration from many living organisms (e.g., lotus leaves, rose petals, pitcher plants, and Stenocara beetles) [ 79–81 ] promotes the development of micro‐/nano‐hierarchical structures for superwetting surfaces (e.g., CA of >150° for superhydrophobic or <10° for superhydrophilic states).…”
