“…Clear surface waves can be observed in the lateral force map, and these are caused by frictional stick-slip. 49 Stick-slip is very commonly observed, and for polymer samples, it sometimes results in the creation of periodic surface structures caused by plastic deformation. 49 Deformation due to the action of load and shear is also observed for polyHEMA-2.5, but here, a hill of the hydrogel material forms in front of the moving tip and the tip does not manage to climb over this hill fully (except at very low forces).…”

“…Compared with the bare sample, new characteristic peaks for C and O appear on the superhydrophobic surface. The existence of C and O may be related to the formation of [CH 3 (CH 2 ) 16 COO] 3 Al on the aluminum surface [31], suggesting the successful modification of the aluminum surface by stearic acid. Figure 5 presents the XPS spectra of the superhydrophobic aluminum surface.…”

“…However, when exposed to aggressive media, especially chloride in the environment, aluminum and its alloys inevitably undergo serious corrosion, which considerably hinders their number of applications. Numerous efforts have been made to inhibit metal corrosion, including organic coatings [1][2][3], inhibitors [4,5], cathodic protection [6] and surface modification [7]. Inspired by lotus leaves, a superhydrophobic surface with a water contact angle greater than 150°and rolling angle smaller than 10°, has attracted great attention over the past decades, because it presents significant potential in the fields of selfcleaning [8,9], corrosion resistance [10][11][12], oil-water separation [13] and energy conservation [14].…”

A superhydrophobic surface featuring high roughness and low surface energy is designed for effective corrosion protection on aluminum via a facile and cost-effective electrochemical route. The effects of the electrolyte composition and electrodeposition time on the surface wettability were investigated. Moreover, the corrosion resistance performance of the as-prepared superhydrophobic aluminum surface was studied using electrochemical impedance spectroscopy and electrochemical noise techniques. The results show that the superhydrophobic aluminum surface obtained at 2 V for 20 min has a high static water contact angle of 155.8°. Both the average corrosion rate and pitting intensity are remarkably inhibited by the as-prepared superhydrophobic surface on aluminum. Moreover, the static water contact angle for the obtained superhydrophobic surface remains above 150°after exposure to 3.5 wt% NaCl solution for 30 days. This facile and economical superhydrophobic surface, with its excellent anti-corrosion property and stability, shows significant potential for use in industrial applications.

“…The resistance of films to strong acid was tested using a standard protocol (HG2‐1144‐78) by coating them on an Fe plate (50 × 50 × 2 mm) by scraping and preparing three samples for parallel experiments under constant temperature and humidity conditions. The sample was immersed in 10% HCl solution in a beaker which was covered and replenished regularly . For acid resistance measurements, the immersed sample was observed every 24 h. A similar procedure was applied to test the resistance of the coating against weak acid (30% H 2 O 2 solution) and water via a standard test protocol (GB/T 1763‐1989) .…”

In this study, a new modifier (KPG) was prepared by modifying graphene oxide with -glycidoxypropyl trimethoxysilane (KH560) and polydimethylsiloxane (PDMS). KPG was in turn added to aqueous urethane acrylate for the fabrication of waterborne polyurethane polyacrylate emulsion modified with KH560-PDMS composite (KPG/WPUA). Textural characterizations of the KPG/WPUA coating were achieved via Fourier transform infrared, SEM, TGA and AFM techniques, which revealed that the KPG/WPUA film possessed a smooth surface. The synthesized KPG/WPUA films were tested for mechanical properties, hydrophobicity and acid/water corrosion performance which suggested their highly hydrophobic surface. KPG/WPUA with 0.1% KPG showed a contact angle of 118.35 ∘ , 30.35 ∘ higher than that of pristine WPUA. The KPG/WPUA film exhibited higher thermal stability, i.e. a 5% weight loss temperature of 305 ∘ C, which was 30 ∘ C higher than that of pristine WPUA film. The Young's modulus and elongation at break of the KPG/WPUA film were 34.1 MPa and 74.88% respectively, which were higher than that of WPUA film. Furthermore, KPG/WPUA films exhibited greater resistance (without obvious blistering and the white spotting phenomenon) to H 2 O 2 , HCl and water corrosion than pristine WPUA. The superior performance of KPG/WPUA films was attributed to the network chain structure formed upon the introduction of KPG into WPUA. The outstanding performance of KPG/WPUA films in terms of mechanical properties, thermal stability and high resistance to acidic and water corrosion makes them interesting alternative contenders for target applications.
