“…In [24], it was concluded that the wettability of the droplet on triangular wave micro-structure surfaces calculated by volume of fluid (VOF) method was in good agreement with the wettability of the droplet on experimental silicon surfaces. Therefore, in this paper, the dynamic wettability of the triangular wave micro-structure surfaces was calculated by VOF method.…”

Wettability plays a vital role in many fields. In this paper, the shortcomings of current experimental measurement of dynamic wetting characteristics are described. The dynamic wettability of droplets on the simplified triangular wave micro-structure surface is studied by volume of fluid method. The results are compared with the dynamic wettability of droplets on the smooth surface and the rectangular wave micro-structure surface. The results show the similarities and differences of the motion characteristics of droplets on smooth surface and different micro-structure surface. Under the action of volume force, the droplets are first deformed and then moved. The droplets move as a whole on the smooth surface. But the droplets partially slip on the micro-structure surface, and the threephase contact point on the left side does not move.

Functional surfaces with attractive properties, such as superhydrophobicity and omniphobicity often rely on the synergy between intrinsic material properties and dual scale micro‐ and nano‐hierarchical structures for achieving desired wettability. Historically, engineered liquid repellent surfaces have attracted a great deal of interest from academia and industry due to their broad application prospects. Hence, for several years, there have been significant scientific efforts by researchers exploring state of the art manufacturing technologies that are efficient and yet cost effective to produce functional liquid repellent surfaces at an industrial scale. This technical review summarizes the various advanced and state of the art polymer processing technologies employed to fabricate the micro‐ and nanostructured polymer surfaces, with a special focus given to superhydrophobic and omniphobic applications. Here, we discuss the merits and limitations of each fabrication methods available for micro‐ and nanostructuring of polymer‐based surfaces. In addition, an attempt has been made to provide insight into the relationship between geometry of micro/nanostructures (size and shape) and intrinsic wettability on liquid repellency. A special section has been devoted to feature and document all commercialization efforts, including various commercially available products that were developed in the past decade. Finally, outlook and the development trend in the polymer micro‐ and nanostructured surfaces are highlighted to lead future research.

Owing to its hydrophobic nature, polymers are more commonly employed to impart superhydrophobicity over different surfaces. This review gives a brief account on the theories behind superhydrophobicity and techniques employed to develop superhydrophobic coatings over metal, fabrics, papers, sponges, foam, glass, wood, mesh, concrete and ceramic surfaces. Fine‐tuning of superhydrophobic polymeric surfaces is much required to enhance corrosion control, oil‐water separation, self‐cleaning, drag reduction, anti‐microbial, anti‐bio‐fouling, anti‐icing and desalination properties. Methodology and current developments in the designing such superhydrophobic polymeric surfaces are highlighted. To conclude, the challenges to be addressed by the scientific world to solve the problems associated with mass production, stability and durability of the coatings, development of hierarchical micro‐nanostructures are detailed.
