“…and the E corr increased from −0.887 to −0.754 V. The increase of E corr and the decrease of i corr indicate that the superhydrophobic surface improves the corrosion resistance of the coating. 43 The corrosion resistance of the SiO 2 -GSR film is mainly due to the repulsion of corrosive solution by superhydrophobicity and the barrier effect of graphene sheet, as shown in Figure 9. In the early immersion, SR coating protects the substrate by preventing the penetration of corrosion solutions (Figure 9(a)).…”

The corrosion caused by marine organisms adhering to the wall surface is one of the main reasons for the failure of ships and equipment, and leads to shortened life and increased maintenance costs, and this has seriously affected the development of the national economy. Therefore, it is very important to develop a new composite material to protect the metal substrate from biological corrosion. In this article, a superhydrophobic surface was prepared by simply spraying silicone rubber emulsion containing hydrophobic SiO2 nanoparticles onto a graphene silicone rubber (GSR) pre-coated substrate (SiO2-GSR). The antifouling ability was investigated under laboratory conditions and real marine environments, and the results show that the SiO2-GSR coating has good antiadhesion effect and longer antifouling ability. The anticorrosion performance was evaluated by electrochemistry methods, and the SiO2-GSR has good corrosion resistance ability. Additionally, the SiO2-GSR film still exhibited a strong antifouling and anticorrosion ability after immersed in marine environment for 6 months. Therefore, SiO2-GSR can be applied to the maritime field as an effective antifouling and anticorrosion coating.

“…Further, it is also noted that the elongation of the PVA is significantly affected by the agglomeration of PPy nanocomposite in the PVA thin film when doped above 6 wt%. The maximum elongation of Ppy nanocomposite in PVA by 6 wt% may be due to the limit of critical concentration [32][33][34] .…”

Polypyrrole/SnO2 nanocomposites were created using in-situ polymerization techniques. The nanocomposites were described using scanning electron microscopy (SEM) and transmission electron microscopy (TEM), and their thermal properties were studied using a Differential Scanning Calorimeter (DSC). The DC conductivity of the samples was measured as a function of temperature from 30 ℃ to 1900 ℃, and it was observed that increasing the concentration of tin oxide particles improves conductivity due to polaron hopping and composite chain length extension. The tensile strength of PPy nanocomposites doped in PVA thin film up to 6 wt% indicates 64.2 MPa, which may be related to the homogenous distribution of PPy nanocomposite in PVA. The study reveals that because 50 wt% of the nanocomposites have the highest conductivity and sensitivity, these nanocomposites may be useful in future applications.

“…The resulting composite surfaces are characterized by the surface morphology, chemical composition, and functional group structure. Furthermore, we explored the variations in hydrophobic properties of single and composite coatings through wettability, self-cleaning, adhesion, and corrosion resistance (Xie et al, 2018;Ali et al, 2020).…”

The superhydrophobic coatings with excellent performance are prepared on the brass substrate to improve its application limitations in real production. In this article, the superhydrophobicity was obtained by the modification of TiO2 nanoparticles, and the FAS/STA-TiO2 superhydrophobic coating of the composite structure was obtained by modification of 1, 1, 2H, 2H-perfluoroquine trimethyl silane (FAS). By using scanning electron microscopes (SEMs), X-ray spectrometers (EDSs), and Fourier transform infrared (FTIR) spectrometers, the surface morphology, chemical composition, and functional group structure of the samples were analyzed in turn. Experiments show that the water contact angle of the FAS-modified STA-TiO2 coating reaches 161.3°, and the sliding angle is close to 1.2°. Based on the chalk dust containment, it has enabled noticeable self-cleaning properties. The composite superhydrophobic coating also presents enhanced adhesive strength compared with the single coating by the tape peeling experiment. Moreover, the composite coating has a corrosion current density as low as 8.41 × 10-7 A/cm2, and the largest |Z| in low frequency in a 3.5% NaCl solution to achieve better protection of the brass substrate. It is also not difficult to see that FAS/STA-TiO2 coating can not only improve the corrosion resistance of brass substrates but also be applied to other metal substrates.
