“…Two elements must be present to construct a superhydrophobic surface: rough surface texture with a distinct binary structure and surface chemistry modification with a low-free-energy coating 7 . Chemical vapour deposition 7 , sol–gel 8 , chemical etching 9 , spray 10 , and electrodeposition 11 have all been presented as ways to generate bio-inspired SHP surfaces by changing surface morphology and chemical compositions. However, most of these approaches are limited by the need for specialized equipment or difficult process control 12 .…”

In this work, Ni and Ni-graphene, Ni-G, films were electrodeposited on copper substrate by potentiostatic deposition. To achieve superhydrophobicity, myristic acid, MA, was used to modify the surface of the electrodeposited coatings. The manufactured Ni film modified with myristic acid, Ni-MA, and the Ni-G film modified with myristic acid, Ni-G-MA, show excellent superhydrophobic, SHP, properties with a water contact angle of 159° and 162°, respectively. The surface morphology of the prepared SHP films was investigated using a Scanning Electron Microscope, and the results revealed micro-nano structures in both Ni-MA and Ni-G-MA films. The Fourier Transform Infrared Spectrophotometer data showed that the Ni-MA and Ni-G-MA films were successfully grafted on the copper metal. The Ni-G-MA film possessed higher chemical stability and mechanical abrasion resistance than Ni-MA. The Ni-MA and Ni-G-MA films exhibit long-term durability in the outdoor environment for more than four months. The potentiodynamic polarization and electrochemical impedance spectroscopy results demonstrated that the SHP films on the copper substrate exhibit remarkable corrosion resistance in 0.5 M NaCl.

“…Although Cu and its alloys are very stable in dry environments, Cu is easily corroded in humid environments, which limits its practical application [ 2 ]. Therefore, how to improve the corrosion resistance of Cu in humid environments has become a heated topic in material research [ 3 ]. Because of its great potential and application in the field of corrosion protection, superhydrophobic film has attracted extensive attention in recent years [ 4 , 5 ].…”

Using milling method, a 0.1 mm flat-bottom sharp knife was used to mill the surface of Cu substrate in a CNC engraving machine to construct the microstructure of rectangular bumps, and rectangular bumps with different sizes and different distances were prepared by changing the distance between cutter tips. After deburring and stearic acid modification, a superhydrophobic Cu surface with excellent mechanical durability and stability was successfully prepared. Through friction and wear experiments, the contact angle of the superhydrophobic Cu surface decreased slightly while retaining excellent corrosion resistance.

“…The peaks at 3300 cm −1 correspond to O–H bonds stretching vibrations of stearic acid, complemented by the C–OH band at 1158 cm −1 due to the hydroxyl groups 47 . The two peaks at 2927 cm −1 and 2857 cm −1 are assigned to –CH 2 – asymmetry and symmetry vibration 48 . The peak at 1745 cm −1 is attributed to the C=O stretch.…”

Superhydrophobic coatings were successfully fabricated on steel substrates using potentiostatic electrodeposition of Ni and Ni-graphene, Ni-G, coatings followed by immersion in an ethanolic solution of stearic acid, SA. Rice straw, an environmentally friendly biomass resource, was used to synthesize high-quality graphene. The Raman spectra proved the high quality of the produced graphene. The Fourier transform infrared spectroscopy, FTIR, results showed that the Ni coating grafted with stearic acid, Ni-SA, and the Ni-G composite grafted with stearic acid, Ni-G-SA, were successfully deposited on the steel substrate. The scanning electron microscope, SEM, results showed that the prepared superhydrophobic coatings exhibit micro-nano structures. The wettability results revealed that the values of contact angles, CAs, for Ni-SA and Ni-G-SA coatings are 155.7° and 161.4°, while the values of sliding angles, SAs, for both coatings are 4.0° and 1.0°, respectively. The corrosion resistance, chemical stability, and mechanical abrasion resistance of the Ni-G-SA coating were found to be greater than those of the Ni-SA coating.
