“…In contrast, even after 1000 cycles of abrasion, most PTFE nanoparticles remained in the micronano structures and the superhydrophobic textures barely deteriorated (Figure f). Similarly, a tape-peeling test was also conducted to verify the adhesion between nanoparticles and the substrate according to a commonly used method. , We observed that the superhydrophobicity hardly deteriorated after 200 cycles of tape peeling, which confirmed the crucial contribution of the stainless steel frames in protecting the surface from the mechanical force (Figure S6). Therefore, the synergetic effect of stainless steel and PTFE nanoparticles provides the surface with superior abrasion resistance and durable mechanical robustness.…”

Superhydrophobic surfaces have attracted considerable attention because of their unique characteristics for widespread applications such as self-cleaning, deicing, antifouling, and hydrodynamic drag reduction. However, previous research has failed to attain the required mechanical and chemical robustness of a superhydrophobic surface simultaneously, which has significantly limited its application in complex and practical scenarios. In this work, we designed and fabricated a mechanically and chemically robust superhydrophobic surface that is made of laser-ablated microstructured stainless steel frames filled with fluoropolymer nanoparticles. The stainless-steel frames serve as a protective cover that significantly enhances the mechanical durability of the surface, and the fluoropolymer coatings subsequently improve the resistance to chemical corrosion due to their intrinsic chemical inertness. This synergetic effect of mechanical protection and chemical inertness empowers the superhydrophobic surface of robust superhydrophobicity after 1000 cycles of sandpaper abrasion and immersion in extremely corrosive chemical solutions of 1.5 mol/L NaOH or 0.75 mol/L H2SO4 for 300 h. In addition, our superhydrophobic surface has retained anticorrosion and wear-resistant properties even after 30 days of continuous UV and thermal exposure, salt spray, and seawater immersion. Thus, we envision that such superhydrophobic surfaces with their superior mechanical robustness, chemical corrosion resistance, and scalable manufacturability are capable of expanding their operational lifespan in practical engineering applications.

“…Besides, the corrosion potential ( E corr ) of the steel coated with a nanosensor-embedded PU coating positively shifted to −0.52 V, which suggests that the metal oxidation process was greatly inhibited. 58 In addition, the active anticorrosion capability of the nanosensor-based coating was further confirmed by the polarization resistance ( R p ). As can be seen, the steel coated with GO–ZIF–Phen/PU coating displays the greatest R p value (3097 kΩ cm 2 ), which is one order of magnitude higher than the steel beneath the pure PU coating.…”

“…There are two main methods to fabricate polymer coatings on Mg alloys, namely dip coating and spin coating [ 65 ]. Wang et al [ 66 ] reported that silane-coupling agent calcium hydrogen phosphate dihydrate (SCA/DCPD) coating prepared by dip-coating method resulted in AZ60 alloy with improved corrosion resistance, whereas silane-coupling agent calcium carbonate (SCA/CaCO 3 ) coating prepared by biomimetic deposition method resulted in AZ60 alloy with improved biocompatibility.…”
