“…Different chemical and physical methods for the fabrication of rough surfaces and subsequent application of low-surface-energy coatings on these rough surfaces have been explored, e.g., lithography, [77] sublimation, [78] plasma techniques, [79] self-assembled monolayers, [80] electrochemical methods, [81] electrohydrodynamic/electrospinning techniques, [82] and many more. Electrohydrodynamic techniques proved to be effective methods for the preparation of lotus-leaf-like porous microsphere/nanofiber composite films.…”

In this review a strategy for the design of bioinspired, smart, multiscale interfacial (BSMI) materials is presented and put into context with recent progress in the field of BSMI materials spanning natural to artificial to reversibly stimuli‐sensitive interfaces. BSMI materials that respond to single/dual/multiple external stimuli, e.g., light, pH, electrical fields, and so on, can switch reversibly between two entirely opposite properties. This article utilizes hydrophobicity and hydrophilicity as an example to demonstrate the feasibility of the design strategy, which may also be extended to other properties, for example, conductor/insulator, p‐type/n‐type semiconductor, or ferromagnetism/anti‐ferromagnetism, for the design of other BSMI materials in the future.

“…superhydrophobic surfaces where the contact angle is larger than 150 • ) are mostly used in self-cleaning surfaces [2], tunable lenses [3], micro-fluidic systems [4] and non-adhesive coating [5,6]. Since the last two decades, the wetting phenomena on superhydrophobic surface has become a subject of fundamental research in physics [7][8][9], chemistry [10], biology [11,12] and materials science [13,14]. In material science, many metallic superhydrophobic surfaces are mostly used as anticorrosive surfaces.…”

a b s t r a c tWater condensation, a complex and challenging process, is investigated on a metallic (Zn) surface, regularly used as anticorrosive surface. The Zn surface is coated with hydroxide zinc carbonate by chemical bath deposition, a very simple, low-cost and easily applicable process. As the deposition time increases, the surface roughness augments and the contact angle with water can be varied from 75 • to 150 • , corresponding to changing the surface properties from hydrophobic to ultrahydrophobic and superhydrophobic. During the condensation process, the droplet growth laws and surface coverage are found similar to what is found on smooth surfaces, with a transition from Cassie-Baxter to Wenzel wetting states at long times. In particular, it is noticeable in view of corrosion effects that the water surface coverage remains on order of 55%.

“…The hierarchical structure for increased roughness provides an efficient strategy to increase the liquid-air contacting area. 40 In addition, the modification of the lowsurface-energy coating of HS(CH 2 ) 11 CH 3 is favorable for reducing y 1 . Hence, the rough gold aggregates and HS(CH 2 ) 11 CH 3 coating should contribute to superhydrophobicity.…”

Combining a stimuli-responsive material and the Marangoni effect, a microactuator containing a ultraviolet (UV)-light-responsive photoresist and surfactant is fabricated. The locomotion of a functionally cooperating device loaded with the microactuator can be initiated by irradiation with 365 nm UV light, ceased by the removal of the UV light and restarted by re-exposure to the UV light. Moreover, the device exhibits good direction control via selective irradiation of photoresponsive microactuators at designated locations. This work is the first example using the chemical Marangoni effect to produce photoresponsive ON-OFF-ON motion of a macroscopic object on water surfaces with little impact on the experimental environment and opens up new opportunities for the design of novel advanced functional materials with controlled properties.
