“…Whereas without nanoparticles, the surface was not able to maintain its durability. Various other studies [49][50][51][52][53]63,[74][75][76] using different SRCAs and LSEAs on Q235 iron plates, steel, and substrateindependent surfaces 29,54,55,68,69 in Table 4 have been reviewed but the clear evidence toward the durability of these special surfaces is required to be addressed . Various studies showed different perspectives of certain limits toward stability, such as a number of withstanding cycles or up to certain number of hours; however, a standard definition on durability is not clear, which motivate us to work for certain applications where a specific time/cyclelimit and overall life cycle of the modified surface are important.…”

Superamphiphobic (water and oil repellent) surfaces have distinct application areas such as anti-corrosion, anti-friction, anti-icing, self-cleaning, etc. To fabricate these types of surfaces, the base material must have low surface energy and dual-scale roughness (micro and nano levels). The durability of such surfaces is indicated by the duration up to which they remain stable and effective. When mechanical forces interact with these surfaces, it deteriorates the surface integrity and ultimately degrades its superamphiphobic property. Hence, these surfaces have very limited mechanical wear sturdiness and long-term durability. Therefore, in this article, efforts have been made to review the different types of mechanical durability tests performed on superamphiphobic metallic and non-metallic surfaces. Moreover, various kinds of surface texturing techniques in context with durability of such surfaces have been discussed. Finally, from the reported literature, critical conclusions, challenges, and scopes for future work have also been presented.

“…The absorption vibration at 801 cm À 1 was assigned to the SiÀ OÀ Si stretching vibration and became stronger due to the synthesis of SiO 2 on the ATP. [38] In the superhydrophobic coating, the new band at 908 cm À 1 was attributed to vibration of epoxy functional groups form GPTMS, which bonded F-ATP@SiO 2 particles to the surface of magnesium alloy sheet as a binder. [32] In order to further characterize the roughness of the prepared superhydrophobic coatings, 3D optical microscope was used to evaluate the surface roughness.…”

To improve the corrosion resistance of magnesium alloys, superhydrophobic coatings were prepared by employing fluorinated attapulgite@SiO2 (F‐ATP@SiO2) particles and silanes via a facile one‐step spraying technique in this study. Surface morphology, chemical compositions, roughness and wettability of the coatings were comprehensively investigated by Field emission scanning electron microscopy (FESEM), Fourier transform infrared spectra (FTIR), 3D optical microscope and contact angle techniques, respectively. Corrosion resistance of the coatings was evaluated by potentiodynamic polarization test and electrochemical impedance spectroscopy (EIS). Results indicated that the coatings exhibited superhydrophobicity due to its micron scale mastoid structure and low surface energy of F‐ATP@SiO2 particles. The superhydrophobicity and anticorrosion performance of the coatings increased with the dosage increase of F‐ATP@SiO2 particles. The water contact angle of the prepared surface can reach as high as 161° with sliding angle of 4°. Icorr of the coatings can reach 5.519×10−8 A cm−2, decreased by 3 orders of magnitude compared to bare AZ31, which showed excellent anticorrosion performance. With the prolongation of immersion time, the EIS analysis indicated that the anticorrosion property of the coating degraded gradually. Based on the electrochemical analysis, the corrosion protection mechanism of the superhydrophobic coating was proposed.

“…So far, many methods for creating super-hydrophobic coatings have been reported, but few products have been applied to them in practice [43]. The main reason for this limited application is not the cost or difficulty of mass production, but its poor stability [44].…”

In order to solve the problem of dust accumulation on the fin surface of a mine air cooler, a method of preparing super-hydrophobic polyurethane (SPU) coating based on waste cooking oil (WCO) was proposed. Firstly, the polyurethane prepolymer was synthesized with WCO as a raw material, and then the polyurethane prepolymer was modified with amino-terminated polydimethylsiloxane (ATP) to obtain SPU emulsion. The chemical structure and thermal stability of SPU were characterized by infrared spectrum and thermogravimetric analysis. A series of nanocomposites were prepared by combining modified silicon carbide (APT-SiC) particles and SPU emulsions. According to the parameters of pull-off strength, contact angle, sliding angle and thermal conductivity, the filler ratio of nanocomposites was optimized. The test results show that when the content of APT-SiC particles is 20 wt %, super-hydrophobic polyurethane coating can be obtained. The coating has good pull- off strength and thermal conductivity, and the contact angle and sliding angle are 161° and 3°, respectively. In addition, the practical application of the super-hydrophobic polyurethane coating was tested by related experiments. The experimental results show that the coating has good self-cleaning, wear resistance and anti-corrosion performance, can meet the requirements of air coolers in special environments, and has great application prospects.
