“…Research has been focused mostly on synthesis of multifunctional superhydrophobic coatings for water-repellent and self-cleaning applications [6][7][8], where (super)hydrophobicity is regulated through multiscale roughness structures formed by various nanoparticles, i.e., silica, TiO 2 , ZnO, etc. [9][10][11]. Polymer coatings, on the other hand, present an effective physical barrier between the metal and the environment containing aggressive species, and serve as a reservoir for corrosion inhibitors that help the steel surface to resist attacks from aggressive species [12].…”

We present the results of one year observation of wetting and corrosion properties of nanosecond fiber laser-textured stainless steel, uncoated and coated with epoxy or FAS (fluoroalkylsilane)-TiO2/epoxy. A comparative study was performed on samples kept under ambient conditions and in reduced air pressure and humidity. The results show the ability to induce wettability conversion from initially superhydrophilic to final superhydrophobic state either indirectly by ageing the uncoated laser-textured surface or directly by application of FAS-TiO2/epoxy coating. The storage conditions significantly influenced the wettability development of uncoated laser-textured steel, i.e., the process of ageing was slowed down in reduced air pressure and humidity. Detailed surface chemical analysis revealed that adsorption of the organic matters from the surrounding media influences the wettability conversion and ageing. However, the ageing of the coated surfaces was not affected by the storage conditions. Corrosion stability of uncoated laser-textured surfaces was enhanced over time due to the wettability transition, depending on their morphology. Coatings represent a superior barrier over the texture and wettability with the stable long-term surface protection against aggressive media.

“…This included the fabrication of multifunctional coatings with superhydrophobic properties for self-cleaning applications based on the use of various nanoparticles (i.e., nanosilica, TiO 2 , CuO, ZnO). Their properties are tailored via surface multiscale roughness for specific applications [17,18]. Water attractive, superhydrophilic surfaces show the potential for ultrafast drying with special properties, such as antifogging or evaporative cooling [7,19].…”

An AISI 316L surface was functionalized by the adsorption of hydrophilic epoxy and epoxy/TiO2/epoxy coatings and hydrophobic epoxy/fluoroalkylsilane-functionalized FAS-TiO2/epoxy coatings. We characterized the coatings’ wettability, morphology and average surface roughness and discussed the influence of surface wettability and morphology on the coefficient of friction and the wear resistance. Experiments were performed in dry, distilled water and in a simulated physiological solution (Hank’s solution). In the case of dry sliding, a lower coefficient of friction is achieved for both TiO2 coatings compared to the pure epoxy coating. In a water environment the same level of friction is shown for all three coatings, whereas in Hank’s solution the friction is reduced for the hydrophilic epoxy/TiO2/epoxy coating, increased for the hydrophobic epoxy/FAS-TiO2/epoxy coating and has no effect on the pure epoxy coating. The results show that the corrosion resistance is significantly improved for the hydrophobic epoxy/FAS-TiO2/epoxy coating compared to the hydrophilic pure epoxy and epoxy/TiO2/epoxy coatings.

“…Some researches demonstrated that hydrophobic or superhydrophobic films can protect alloys by forming inhibitive film, which renders surface water repellent to prevent the corrosive attack and significantly enhances corrosion resistance as compared to untreated specimens . Studies about superhydrophobicity used to protect metal have been focused on managing the surface of metal, yet more and more attention have been paid to coating materials with superhydrophobic structure . It provides a new way to improve the corrosion resistance of metal surface sealed anodic layers.…”

We report a simple approach for the preparation of superhydrophobic polyaniline (PANI) and its application for the corrosion protection coatings. First, PANI was synthesized conventionally by oxidative polymerization with APS. Subsequently, PANI with different wettability was obtained by modification with different surfactants. The surface modification of PANI with three different surfactants (sodium dodecylbenzenesulfonate, polyethylene glycol, and cetyltrimethylammonium bromide) provided excellent surface superhydrophobicity (water contact angle >150°). The structure and morphology of as‐prepared PANI were characterized with Fourier transform infrared, Energy dispersive X‐ray spectroscopy, and Scanning electron microscopy. Corrosion protection performance of PANI with different wettability was evaluated in 3.5% NaCl electrolyte using Tafel polarization curves and electrochemical impedance spectroscopy. The results indicated that various superhydrophobic PANI coatings have better anticorrosion performance as compared to the hydrophilic PANI. © 2016 Wiley Periodicals, Inc. J. Appl. Polym.
