“…(4) By analyzing its surface structures and chemical composition, the superhydrophobicity of the laserablated surface after annealing was related to the formation of hierarchical micro/nanostructures as well as the absorption of organic compounds with low surface free energy in air, and the difference in surface adhesion force was mainly ascribed to the difference in surface roughness. (5) It was demonstrated that a superhydrophobic surface with a low adhesion force could be used in a selfcleaning application and that superhydrophobic surfaces with different adhesion forces could be applied in no-loss liquid transportation.…”

“…The lotus leaf exhibits low adhesion to water such that water droplets easily slide from its surface. Superhydrophobic surfaces with low adhesion could be applied in anti-icing, drag reduction, and self-cleaning applications. In contrast, the rose petal exhibits high adhesion to water, where water droplets tightly contact with its surface. Superhydrophobic surfaces with high adhesion are suitable for no-loss liquid transportation, microfluidic systems, and water collection. , …”

“…The uncoated (hydrophilic) sample directly falls down into water, while the coated (superhydrophobic) sample still floats on water due to the surface tension of the water. Figure 8(c) shows the mechanism of difference in buoyancy between the uncoated and coated samples, which is related to the watergassolid contact interface [45][46][47][48][49][50][51][52][53][54][55][56][57]. When the uncoated sample is put into water, the water surface is concave, and the interfacial tension direction ( WA  ) is downward due to the uncoated sample is hydrophilic (θ < 90°) (Fig.…”

“…[24][25][26] Moreover, the 3D printing of some widely utilized materials in conventional membranes like polyvinylidene fluoride (PVDF) and polyethersulfone (PES) is not yet feasible. [3,27,28] Figure 1 shows the schematic timeline of the evolution of 3D printing, the application of 3D printing in membrane technology, and the number of publications by searching for keywords '3D printing', 'water', and 'membrane' in the last decade. The data shows more than 160 publications in the field of 3D-printed membranes for water treatment applications in the last 10 years.…”
