“…It is worth mentioning that the larger arc diameter represents higher charge transfer resistance. 18 As shown in Fig. 5(a) , when the immersion time was 40 min, the arc radius of the superhydrophobic sample was the largest, which is consistent with the results of the polarization curves.…”

“…The interface is created by retaining air within the nano-scale topography of the surface, which reduces the contact area of water droplets, producing a highly non-wetting, low adherence surface [6,7,11]. A superhydrophobic surface (SHS) refers to a surface with a contact angle of more than 150° [8,12,13]. SHSs have been shown to provide effective corrosion protection on a range of metallic substrates, such as steel [14,15], copper [16], magnesium [17] and zinc [9,[18][19][20][21].…”

“…Liang et al produced a superhydrophobic coating on a zinc surface implementing a simple one-step hydrothermal growth technique using stearic acid and silicon dioxide (SiO2) particles [13]. The authors reported excellent corrosion performance when the coating was immersed in aqueous sodium chloride solution and contact angle measurements were recorded of up to 160°.…”

Hydrophobicity on steel-based metallic surfaces provides an advantage in limiting corrosion and debris buildup on the surface, thereby, improving the substrate performance. An experimental investigation was conducted on the development of zinc stearate and silicon dioxide coatings on the surface of hot-dipped galvanised zinc-coated steel substrates, which could be used to induce superhydrophobicity. Under optimal formulation and processing conditions, a contact angle of 146° could be produced within a 120-min processing window. This represents a reduction in processing time of 67% over previous literature using similar chemistry. In addition, we proved that costly nano silicon dioxide can be replaced by lower cost micro silicon dioxide without decreasing the performance of the coating contact angle. Under standard accelerated exposure tests, the coating was shown to reduce oxide build up by a factor of 3 compared to uncoated galvanized steel.

“…The most effective way to deepen and develop research is to enhance the toughness and anti-corrosion performance of epoxy resin by adding nanomaterials to the epoxy resin coating. There are plenty of types of nanomaterials that have been extensively modified for the mechanical and anti-corrosion properties of epoxy resins, such as carbon nanotubes (CNT), 10,11 halloysite nanotubes (HNT), [12][13][14] layer double hydroxide (LDH), [15][16][17] graphene, 18,19 nano silica particles, 20,21 and sepiolite. 22,23 Metal organic frameworks (MOFs), composed of the metal ions as a precursor and organic compounds as ligands, are called the new class of nano porous materials.…”

Herein, a new strategy for improving epoxy coatings' anti-corrosion performance has been developed, which combined NH 2 -Ce-MOF with graphene oxide (GO) by hydrothermal method. First, the nanocomposite material's morphology and structure (GO-Ce-MOF) were confirmed by Fourier transform infrared, X-ray diffraction, TG, X-ray photoelectron spectroscopy, and scanning electron microscope (SEM) studies. The dispersity of the composite in the epoxy coating was evaluated by SEM and mapping analysis. Meanwhile, the anti-corrosion of as-prepared composite coatings was investigated in detail by the electrochemical impedance spectroscopy (EIS) and the Tafel polarization curve test. The results illustrated that 2.0 wt% GO-Ce-MOF/EP greatly enhanced the composite coating's anti-corrosion performance compared to other coatings. The reasons for the improvement of the anti-corrosion performance of the composite coating are attributed to the following two aspects: On the one hand, the addition of GO can provide a physical barrier to form a labyrinth effect to slow down the invasion of corrosive media into the metal substrate, on the other hand, the modification of GO can GO-Ce-MOF achieve better compatibility and dispersion in epoxy resin.
