“…In past decades, the mimicking of nature has been very successful in solving global environmental, material, and sustainability problems due to the superior physical and chemical properties exhibited by different animals, plants, and microorganisms [1,2,3,4,5,6,7,8]. As an example, leaves of plants such as Alocasia odora , Calathea zebrina , and Ruelia devosiana show nanostructures that exhibit hydrophilic and superhydrophilic properties [6,7].…”

“…Aside from the surface morphology, the surface and bulk chemistry of the leaves of these plants also contribute to the exhibited wetting properties [6]. Mimicking these nanostructures to attain the same wetting properties can be achieved using different techniques, such as surface modification of polymeric or metallic materials by flame, chemical, laser, or plasma processes [1,2,3,4,5,6,7,8,9,10].…”

Taking inspiration from the hydrophilic and superhydrophilic properties observed from the nanostructures present on the leaves of plants such as Alocasia odora, Calathea zebrina, and Ruelia devosiana, we were able to synthesize cupric oxide (CuO) nanostructures from the plasma surface modification of copper (Cu) that exhibits hydrophilic and superhydrophilic properties. The Cu sheets were exposed to oxygen plasma produced from the P300 plasma device (Alliance Concept, Cran-Gevrier, France) at varying power, irradiation times, gas flow rates, and pulsing duty cycles. The untreated and plasma-treated Cu sheets were characterized by contact angle measurements, scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS) to determine the changes in the surface of Cu before and after plasma treatment. Results showed that plasma-treated Cu sheets exhibited enhanced wetting properties compared to untreated Cu. We attributed the decrease in the measured water contact angles after plasma treatment to increased surface roughness, formation of CuO nanostructures, and transformation of Cu to either CuO2 or Cu2O3. The presence of the CuO nanostructures on the surface of Cu is very useful in terms of its possible applications, such as: (1) in antimicrobial and anti-fouling tubing; (2) in the improvement of heat dissipation devices, such as microfluidic cooling systems and heat pipes; and (3) as an additional protection to Cu from further corrosion. This study also shows the possible mechanisms on how CuO, CuO2, and Cu2O3 were formed from Cu based on the varying the plasma parameters.

“…In order to reach superhydrophobic properties, PEDOT copolymers with both ion exchange functional groups and fluorinated chains were prepared by electro-copolymerization (Figure 19) [104,106]. The authors studied the influence of the percentage of each monomer, the doping state and also the counter-ions of ion exchange functional groups on both the surface hydrophobicity (Figure 19) [104].…”

“…Hence, it was possible to obtain both superoleophobic and hydrophilic properties, which is extremely rare in the literature [105]. Moreover, superoleophobic properties were also prepared with poly(3,4-ethylenedioxypyrrole) PEDOP copolymers with ion exchange functional groups and fluorinated chains [106].…”

In this book chapter, most of the methods used in the literature to prepare switchable and reversible superhydrophobic surfaces are described. Inspired by Nature, it is possible to induce the Cassie-Baxter-Wenzel transition using different external stimuli such as light, temperature, pH, ion exchange, voltage, magnetic field, mechanic stress, plasma, ultrasonication, solvent, gas or guest. Such properties are extremely important for various applications but especially for controllable oil/water separation membranes, oil-absorbing materials, and water harvesting systems.Keywords: superhydrophobic, reversible, switchable, bioinspiration, biomimetism Reversible superhydrophobic surfaces: Part twoThis section provides continuation of the description of the stimuli used in the literature to induce reversible changes in surface wettability. Ion exchangeSince 2004, the researchers have shown that the presence of charged species such as quaternary ammonium groups are sensitive to ion exchange and lead to different surface wettabilities. In 2004, Choi et al. prepared self-assembled monolayers (SAM) with imidazolium groups on smooth Au and Si/SiO 2 substrates [1][2][3]. They studied the effect of a series of anions as shown in Figure 1 and In order to elaborate reversible superhydrophobic properties by ion exchange, gold micro and nanostructured substrates were performed by electroless etching process by immersing silicon substrates in aqueous solution of HAuCl 4 and HF (Figure 2). The surface was then modified by SAM using a thiol terminated by a quaternary ammonium. Then, the surface wettability could be reversely changed from superhydrophilic to superhydrophobic after [20]. Here, the presence of TSPM (sol-gel precursor) was used not only to form a polymer network via intramolecular interactions but also to anchor substrates (Figure 3). The membranes could reversely change from superhydrophobic/highly oleophobic to superhydrophilic/superoleophobic after exchanging Cl − ions by heptadecafluorooctanesulfonic acid (C 8 F 17 SO 3 − or HPS − ) ions. Moreover, the membranes were also highly efficient filter medium for removing multiple contaminants such as SO 2 form waster gas streams. A nother strategy was to deposit polyelectrolyte multilayers poly(diallyldimethylammonium chloride (PDDA) and poly(sodium 4-styrenesulfonate) (PSS) on gold micro and nanostructured substrates [21]. The authors studied the influence of the exchanged ions and the highest properties were obtained by exchanging Cl − (θ w < 5°) ions by PFO − (θ w = 164°). The authors also deposited polyelectrolyte multilayers on micro and nanostructured aluminum substrates obtained by etching in HCl and immersion in boiling water [22,23]. Using PFO − ions, the substrates were superhydrophobic and superoleophobic. When the substrates were immersed in seawater, the PFO − ions were exchanged by hydrophilic Cl − or SO 4 2− making the substrates underwater superoleophobic.

“…Different strategies have been imagined by researchers to control these parameters such as laser treatments, plasma etching, hydrothermal processes, or manmade porous surfaces and the rapid engineering of these porous surfaces . An elegant and efficient pathway to control both these parameters is the electrodeposition of conductive polymers . This strategy allows developing hydrophobic and superhydrophobic surfaces in one step.…”

Here, the combination of both the Staudinger reductive amination and amidification to prepare highly hydrophobic surfaces is reported for the first time. This approach has been studied for surface ante and post‐deposition modification. In the ante‐deposition approach, the combination of both the reactions allows to develop a one‐pot new monomer bearing two different side chains (heterobifunctional surface). The developed monomer has been successfully polymerized and leads to hydrophobic surface (θ > 110°). Similar modifications performed as post‐treatment lead to highly hydrophobic feature (θ > 120°). The difference between the ante and post‐deposition modification is investigated for their roughness and morphologies. The results of this work allow explaining this difference on surface feature and show quality and drawback of both ante and post‐deposition strategies.
