“…31 Asymmetric geometric shape, including cone, triangle, and V-shape groove, is applicable to long-distance, continuous, and high flux fluid transport, originating from the considerable fluid holding ability and directional capillary force on the macroscopic interfaces. 32–34 Moreover, the ratio integration of different types of the fluid-manipulating interface can offer a powerful tool to deal with complicated situations of fluid control, which have been demonstrated as the examples of fog collection, 35–39 multi-bioinspired vapor condenser, 40 and Janus triangle electrodes array for electrolysis. 5…”

“…In recent years, research attention has turned to nature to design fog collectors by mimicking the way some natural organisms capture fogwater. 10−12 There are many organisms in nature that exhibit interesting water harvesting abilities, such as the Namib Desert Beetle, 13,14 cacti, 15,16 and spiders. 17,18 Beetles living in the Namib Desert have a special structure on their backs, which consists of a series of hydrophilic projections distributed on a superhydrophobic surface.…”

Water scarcity is a global problem and collecting water from the air is a viable solution to this crisis. Inspired by Namib Desert beetle, leaf venation and spider silk, we designed an integrated biomimetic system with hybrid wettability and wettability gradient. The hybrid hydrophilic–hydrophobic wettability design that bionomics desert beetle’s back can construct a three-dimensional topography with a water layer on the surface, expanding the contact area with the fog flow and thus improving the droplet trapping efficiency. The venation-like structure with wettability gradient not only provides a planned path for water transportation, but also accelerates water removal under the synergistic effect of gravity and wettability driving force, thus further improving the surface regeneration rate. The collector combines droplet capture, coalescence, transportation, separation, and storage capabilities, which provides new ideas for the design of future high-efficiency fog collectors.

“…Nature is a treasure trove of human development and may bring unexpected inspiration. The excellent water-collection properties of some natural organisms have attracted widespread attention, such as desert beetles, − cactus, − pitcher plants, − and so on. Recently, biomimetic materials with superwettability have been gradually used for fog collection.…”

Various methods to solve water scarcity have attracted increasing attention. However, most existing water harvesting schemes have a high demand for preparation methods and costs. Here, a multi-biomimetic double interlaced wetting Janus surface (DIWJS) was prepared by laser for effective fog collection. The as-prepared surfaces are composed of superhydrophilic points/hydrophobic substrates on the A-side and superhydrophilic stripes/hydrophobic substrates on the B-side. The interlaced wettability and superhydrophilic points on the A side are conducive to capture and permeation of droplets. The superhydrophilic stripes and interlaced wettability on the B-side are conducive to transportation and shedding of droplets. Therefore, the overall fog collection process is accelerated. The proposal of smart farm model validates broad application prospects of DIWJS. This work provides an advanced and multi-biomimetic surface and provides important insights for green, low-cost, and versatile strategies to solve water scarcity issues.
