“…In a recent review, Guo et al 9 argued that natural superhydrophobic surfaces have two main formats, hierarchical roughness and single size fibrous structures. The second type is particularly interesting for polymeric materials as the sizes required are larger and the shapes are more robust.…”

“…3,[8][9][10][11][12][13][14][15][16][17][18][19][20] The roughness shape and size can vary widely from ordered pillars to chaotic roughness, from particles to fibers, and from materials such as metals to inorganic and organic compounds. Owing to the number of reviews recently published, this one will be confined to polymeric surfaces and some of the unique properties offered by them.…”

Superhydrophobicity is the extreme water repellence of highly textured surfaces. The field of superhydrophobicity research has reached a stage where huge numbers of candidate treatments have been proposed and jumps have been made in theoretically describing them. There now seems to be a move to more practical concerns and to considering the demands of individual applications instead of more general cases. With these developments, polymeric surfaces with their huge variety of properties have come to the fore and are fast becoming the material of choice for designing, developing, and producing superhydrophobic surfaces.

“…Nature found a smart way to deal with that by creating hierarchical surface patterns. [1,[4][5][6] In bio-mimetics, this design idea is used to create well-defined surfaces with specially tailored frictional properties, which are transferred from nature to applications. [7] The tribological effectiveness of singlescale surface features has been demonstrated in numerous research works including dry and lubricated conditions.…”

Effects of Multi‐Scale Patterning on the Run‐In Behavior of Steel–Alumina Pairings under Lubricated Conditions

In nature, many examples of multi-scale surfaces with outstanding tribological properties such as reduced friction and wear under dry friction and lubricated conditions can be found. To determine whether multi-scale surfaces positively affect the frictional and wear performance, tests are performed on a ball-on-disk tribometer under lubricated conditions using an additive-free poly-alpha-olefine oil under a contact pressure of around 1.29 GPa. For this purpose, stainless steel specimens (AISI 304) are modified by micro-coining (hemispherical structures with a structural depth of either 50 or 95 mm) and subsequently by direct laser interference patterning (cross-like pattern with 9 mm periodicity) to create a multi-scale pattern. The comparison of different sample states (polished reference, laser-patterned, micro-coined, and multi-scale) shows a clear influence of the fabrication technique. In terms of the multi-scale structures, the structural depth of the coarser micro-coining plays an important role. In case of lower coining depths (50 mm), the multi-scale specimens show an increased coefficient of friction compared to the purely micro-coined surfaces, whereas larger coining depths (95 mm) result in stable and lower friction values for the multi-scale patterns.

“…98,99 These days, superhydrophobic coatings are manufactured by chemical, physical and/or mechanical modifications of both organic and inorganic materials. 69,[100][101][102][103][104][105][106][107][108][109][110][111][112][113] The opposite term of superhydrophobic is superhydrophilic, defined in the previous contribution. 114 This type of surface is also of great interest at this time, although still some questions regarding its definition remain open.…”

The terms superhydrophobicity and superhydrophilicity were introduced not very long ago, in 1996 and 2000, respectively.The former is used to describe exceptionally weak and the latter used to indicate strong interactions of materials and IntroductionAfter more than two centuries of research, capillarity and wetting phenomena still remain popular topics of investigation in many modern surface chemistry laboratories. Curiosity and fascination with rain droplets splashing in a puddle, water droplets decorating flowers, leaves of plants and fruits after rain or watering and colorful soap bubbles shaped at the end of wheat straw have never been stronger and go beyond scientific laboratories. Colorful images of liquid droplets and puddles, illustrating their behavior on a variety of surfaces, thrive in professional journals, popular magazines and Internet. However, terms such as wetting, spreading and contact angle are still puzzling to the layman and beginner researcher. To facilitate
