“…As expected, besides the peaks of Al and O elements, the strong F and weak C and Si peaks belong to the FAS‐17, suggesting that the FAS‐17 coating has been successfully formed on the surface of ANPs. As displayed in Figure c, the high‐resolution C 1s spectra can be divided into five peaks, orderly attributed to the CF 3 (293.6 eV), CF 2 (291.4 eV), CF (290.3 eV), CO (286.1 eV), and CC (284.8 eV), which are thought as the characteristics of FAS‐17 molecules . Only AlO bond is observed in the high‐resolution Al 2p spectra (Figure S4, Supporting Information) after modification due to the limitation of detecting depth.…”

The stability of aluminum (Al) nanoparticles (ANPs) is a key issue that can determine the energetic properties of Al‐based energetic materials. In this study, a surface functionalization approach is employed, using the chemical adsorption and auto polymerization effects of the 1H, 1H, 2H, 2H‐perfluorodecyltriethoxysilane (FAS‐17), to set up a highly stable barrier coating to water and further endow ANPs with long‐term storage stability and self‐activation reaction capability. The FAS‐17‐modified ANPs (AFNPs) with a superhydrophobic surface show their excellent stability in air and unique strengths in corrosion resistance to water by enhancing diffusion resistance of O2 and preventing the hydration reaction. In terms of energetic performances, compared to the two‐step slow oxidation of ANPs, the heat‐release rate of AFNPs is significantly enhanced, resulting in a drastic oxidation process profiting from the surface reaction between the FAS‐17 and alumina (Al2O3) layer. More importantly, the ignition and combustion properties of AFNPs are also greatly improved, which can undergo self‐propagation combustion with a fairly high energy output even after stored in water. At last, the possible mechanisms of oxidation resistance and self‐activation reaction capacities are also proposed.

“…The water contact angle was 161.5 degree and it was showing corrosion resistance efficiency of 98.1%, this leads that it shows good corrosion resistance and water repellency. And also, in case of damage of the top layer of SHS, it can regain its superhydrophobicity by re-modification, so it also shows good repairable property [44]. Ou et.…”

In this era of science where we want things to get more durable and affectless from outer element like corrosion, wear, water, friction, biofouling etc, in this which reduction of wettability is an important phenomenon. we try to mimic water repellence property from our nature to reduce contact with water like a lotus leaf, rose petal, cicada wings etc, this effect is known as superhydrophobicity. In this paper, we have discussed a general introduction about superhydrophobicity and will focus on its application in different fields. In this review paper, there are a lot of examples of coatings that are made by different researchers. We have discussed extensive area of application of superhydrophobicity like corrosion reduction, marine industries, aeroplane industry, self-cleaning, anti-icing, wear resistivity etc.

“…Metal materials are widely used in various fields because of their excellent comprehensive properties [1] . Nevertheless, poor corrosion resistance seriously affects their service life and limits their further applications [2] . It is well known that a surface with superhydrophobicity can play a good protective role on the matrix.…”

A Facile Modifier-free Approach to Fabricate Antistatic Superhydrophobic Composite Coatings with Remarkable Thermal Stability and Corrosion Resistance

Research on antistatic superhydrophobic surfaces has attracted widespread attention in some fields. However, in the application of superhydrophobic materials, fabricating stable and practical superhydrophobic surfaces through facile and low-cost approaches still faces considerable challenges. Herein, a polyphenylene sulfide (PPS)-based antistatic superhydrophobic composite coating with a high water contact angle (166°) and a low sliding angle (2°) was fabricated on a Q345 steel surface through a simple spray-coating method without any modifier. Furthermore, the as-prepared superhydrophobic coating also displayed excellent superhydrophobicity for water droplets at different pH values, as well as self-cleaning, anti-fouling and anti-icing properties. Importantly, the superhydrophobic coating still exhibited superhydrophobicity after calcination at 350 °C for 1 h, indicating its outstanding thermal stability. Excellent antistatic and anticorrosion properties were obtained on the prepared coating surface, which allows the coating to be applied under harsh conditions. Benefiting from the above characteristics, compared with the commercial coating, the as-obtained antistatic superhydrophobic coating may be applied more widely in related fields.
