Due to their superior water-repelling effects, superhydrophobic surfaces have received increasing attention as a promising solution to corrosion of metallic materials. The present article introduces the fundamental theories behind superhydrophobicity followed by a comprehensive review of the recent progresses of this rapidly growing field over the past 5 years. A critical discussion over anticorrosion mechanisms of superhydrophobic surfaces is also provided. For many realistic applications, future efforts are pressingly demanded to prolong the corrosion resistance of these superhydrophobic surfaces. To this end, several important strategies and examples in designing stable, selfhealable, or inhibitor-loaded superhydrophobic surfaces are discussed.

“…In order to investigate the corrosion properties of SHS-coated Al and SLIPS-coated Al, EIS was performed in 3.5wt% NaCl aqueous solution. Before EIS, all samples were immersed in a corrosive medium (3.5 wt% NaCl aqueous solution) for more than 5000 s to obtain a relatively steady electrochemical state in the range of ±0.05 V vs. 26 Fig. 6 shows that the Eoc-t curves of bare Al, SHS-coated Al, SLIPS-coated Al in 3.5 wt% NaCl solution at room temperature.…”

Material corrosion induced by temperature variations is one of the main threats to materials immersed in complex and changeable marine environments. Superhydrophobic surfaces (SHS) are promising for protecting the underlying metal from corrosion. However, temperature variations in underwater environments have hindered the practical application of SHS, thus, their corrosion protection ability is limited. However, slippery liquid infused porous surfaces (SLIPS) can compensate for the aforementioned defects of SHS. In this research, a kind of SLIPS was designed over aluminum for marine corrosion applications using a three-step procedure, consisting of anodization, fluorination and solvent exchange method. The as-prepared SHS and SLIPS were characterized with scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and wettability measurement, and their corrosion properties were investigated by electrochemical impedance spectroscopy (EIS). With the perfluorinated lubricant and aluminium oxide coating, the SLIPS presented high corrosion resistance (2.06 × 10 9 Ω cm 2) in a broad temperature range.

Zhang, et al., Fabrication of durable fluorine-free superhydrophobic polyethersulfone (PES) composite coating enhanced by assembled MMT-SiO 2 nanoparticles, Appl. Surf. Sci. (2016), http://dx. a b s t r a c tA durable fluorine-free polyethersulfone (PES) superhydrophobic composite coating with excellent wearresistant and anti-corrosion properties has been successfully fabricated by combining sol-gel and spray technology. The robust micro/nano-structures of the prepared surface were established by introducing binary montmorillonite-silica (MMT-SiO 2 ) assembled composite particles, which were formed by in-situ growth of SiO 2 on MMT surfaces via sol-gel. Combined with the low surface energy of amino silicon oil (APDMS), the fluorine-free superhydrophoic PES coating was obtained with high water contact angle 156.1 ± 1.1 • and low sliding angle 4.8 ± 0.7 • .The anti-wear of the final PES/APDMS/MMT-SiO 2 superhydrophobic coating can reach up to 60,100 cycles, which is outdistancing the pure PES coating (6800 cycles) and the PES/MMT/SiO 2 coating prepared by simple physical mixture (18,200 cycles). The enhanced wear resistance property can be mainly attributed to the lubrication performance of APDMS and stable interface bonding force between the MMT surface and SiO 2 . Simultaneously, potentiodynamic polarization curves and electrochemical impedance spectroscopy exhibited the outstanding anti-corrosion property of PES/APDMS/MMT-SiO 2 composite coating, with low corrosion current (1.6 × 10 −10 A/cm 2 ) and high protection efficiency (99.999%) even after 30 d immersion process. These test results show that this durable superhydrophobic PES composite coating can be hopefully to provide the possibility of industrial application.
