“…This type of surface can be relatively easily produced in polymeric materials and can be made very stable. 104,105 See Figure 5(a) for a diagram of this type of wetting, although an alternate explanation is that the tops are in a Wenzel wetting state and the bases are not wetted, which would produce a similar mixed state and the same result.…”

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.

“…Generally speaking, the template process includes three steps: preparing a featured template master, molding the replica, and removing the templates. The templates can be natural surfaces, 34,57,[97][98][99][100][101] nanoporous anodic aluminum oxide, 69,102,103 micropatterned Si surfaces, or other artificial structured surfaces.…”

The construction and application of superoleophobic surfaces have aroused worldwide interest during the past few years. These surfaces are of great significance not only for fundamental research but also for various practical applications in self-cleaning, oil-repellent coatings, and antibioadhesion. The unique properties of polymers have made them one of the most important materials for constructing superoleophobic materials. This article reviews recent developments in the design, fabrication, and application of polymeric superoleophobic surfaces.

“…Leaves of Fouquieria columnaris with convex epidermal cells covered with cuticular folds were found to be hydrophobic [16]. Both petals of a red rose with papillate epidermal cells possessing cuticular folds and replicas of Alocasia macrorrhiza (abaxial leaf; papillate epidermal cells) [17] and Rosa landora ( petal; papillate epidermal cells with cuticular folds) showed superhydrophobic properties [18]. Furthermore, cuticular folds on petal surfaces were found to generate iridescence, thus changing the optical properties [19].…”

Plant surfaces covered with three-dimensional (3D) waxes are known to strongly reduce insect adhesion, leading to slippery surfaces. Besides 3D epicuticular waxes, cuticular folds are a common microstructure found on plant surfaces, which have not been quantitatively investigated with regard to their influence on insect adhesion. We performed traction experiments with Colorado potato beetles on five plant surfaces with cuticular folds of different magnitude. For comparison, we also tested (i) smooth plant surfaces and (ii) plant surfaces possessing 3D epicuticular waxes. Traction forces on surfaces with medium cuticular folds, of about 0.5 mm in both height and thickness and a spacing of 0.5 -1.5 mm, were reduced by an average of 88 per cent in comparison to smooth plant surfaces. Traction forces were reduced by the same order of magnitude as on plant surfaces covered with 3D epicuticular waxes. For surface characterization, we performed static contact angle measurements, which proved a strong effect of cuticular folds also on surface wettability. Surfaces possessing cuticular folds of greater magnitude showed higher contact angles up to superhydrophobicity. We hypothesize that cuticular folds reduce insect adhesion mainly due to a critical roughness, reducing the real contact area between the surface and the insect's adhesive devices.
