“…By contrast, other natural surfaces have extremely high θ w but extremely strong water adhesion also called parahydrophobic properties . This is the case of rose petals, Echeveria pulvinata leaves, gecko skin, peach skin, cacti spines or webspinner silks . These properties are extremely important, for example, to capture water droplets even in hot and arid environments and could be used for water harvesting systems ,.…”

Inspired by natural species such as rose petals or Echeveria pulvinata leaves with both high water contact angle θw and high water adhesion (also called parahydrophobic), we have prepared poly(3,4‐propylenedioxypyrrole) with branched alkyl chains on the 3‐position by electropolymerization. The grafting at the 3‐position keeps the NH group free, which is an important condition to obtain nanofibers. Different lengths of branched alkyl chains are studied. Here, using extremely long branched alkyl chains (ProDOP‐br‐C10), it is possible to obtain extremely long and well defined nanofibers leading to porous surfaces (fiber mats) favoring the trapping of air between the surface and water droplets. Using a deposition charge of 200 mC cm−2, extremely high θw up to ≈ 140° while water droplets placed on this surface remained stuck even for a sliding angle of 90°, revealing extremely stron adhesion. These materials could be used in the future in water harvesting systems.

“…There are lots of insects, plants, and animals with superhydrophobic surfaces in nature, and the superhydrophobicity is a remarkable superiority for these species to survive and evolve in their surroundings [15][16][17] . Superhydrophobic surfaces in nature can be divided into two types.…”

Metals and their alloys are irreplaceable engineered materials showing great importance in our society. Light alloy materials (i.e., Mg, Al, Ti, and their alloys) have tremendous application potential in the aerospace, automotive industries, and biomedical fields for they are lighter and have excellent mechanical properties. The corrosion of light alloys is ubiquitous and greatly restricts their utilization. Inspired by the natural anti-water systems, many new designs and conceptions have recently emerged to create artificial superhydrophobic surfaces with great potential for corrosion resistant of light alloy. This review firstly introduces the concept of superhydrophobicity and strategies of producing superhydrophobic surfaces to inhibit the corrosion of light alloys. In addition, we elaborate the durability of superhydrophobic light alloy materials for commercial and industrial applications, and present their anticorrosion mechanism in the corrosive media.

With the explosive growth of the world’s population and the rapid increase in industrial water consumption, the world’s water supply has fallen into crisis. The shortage of fresh water resources has become a global problem, especially in arid regions. In nature, many organisms can collect water from foggy water under harsh conditions, which provides us with inspiration for the development of new functional fog harvesting materials. A large number of bionic special wettable synthetic surfaces are synthesized for water mist collection. In this review, we introduce some water collection phenomena in nature, outline the basic theories of biological water harvesting, and summarize six mechanisms of biological water collection: increased surface wettability, increased water transmission area, long-distance water delivery, water accumulation and storage, condensation promotion, and gravity-driven. Then, the water collection mechanisms of three typical organisms and their synthesis are discussed. And their function, water collection efficiency, new developments in their biomimetic materials are narrated, which are cactus, spider and desert beetles. The study of multiple bionics was inspired by the discovery of Nepenthes’ moist and smooth peristome. The excellent characteristics of a variety of biological water collection structures, combined with each other, are far superior to other single synthetic surfaces. Furthermore, the main problems in the preparation and application of biomimetic fog harvesting materials and the future development trend of materials fog harvesting are prospected.
