“…An alternative approach consists of reversible sorption/desorption of the hydrophilic/hydrophobic compounds on material surface. In combination with previous surface patterning, the reversible transition between superhydrophobic/superhydrophilic properties was achieved in this way . This approach is fascinating, but it also has several limitations, namely the amount of attached compound is limited, and the additional immersion of the surface in the appropriate solution is required.…”

In this paper, the novel material with controllable wettability switching triggered by external electric field is developed. The material is based on the piezopolymer blend of poly(methyl methacrylate) (PMMA) and polyvinylidene difluoride (PVDF), grafted with various hydrophobic and hydrophilic molecules to alter the initial wettability of polymer films. Organic functional groups are grafted on the blend surface via formation of covalent bonds between PMMA and arenediazonium tosylates. The surface chemical structure and morphology of prepared samples are studied by X‐ray photoelectron spectroscopy, UV–vis, and attenuated total reflection infra red (ATR‐IR) spectroscopies, atomic force microscopy (AFM), and confocal microscopy. Attachment of gold nanoparticles to grafted thiol chemical groups is additionally used to confirm the modification procedure. Application of external stimuli in the form of the electric field leads to dramatic changes in water contact angle. Wettability switching is found to be extremely fast and completely repeatable without the destructions of the polymer film. Mechanism of switching is attributed to the morphological smoothening of piezoelectric responsible composite PVDF–PMMA under the application of external stimuli.

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.

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.
