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.

“…Zhu et al [150] formulated g-C 3 N 4 /PVDF composites through wet mixing and hot press molding method, and observed that the inclusion of g-C 3 N 4 efficiently enhanced the thermal permanency and wear behavior of neat PVDF. Wang et al [151] scrutinized the tribocorrosion characteristics in association with superhydrophilicity of PVDF when incorporated with FEP and carbon nanofibers (CNFs). Initially, dispersion solution of 1 g PVDF powders, 0.1 g FEP powders and 0.01 g CNFs was prepared in 10 mL absolute alcohol.…”

Galling is the surface phenomenon which involves adhesion of local contact points and creation of protrusions on the juxtaposition of surfaces owing to high friction, inappropriate tribological loading, starved lubrication and high contact pressure (~ 1000 kPa). All these factors result in severe plastic deformation varying from 8000 to 10,000 µε (ε-strain) and diffusion of materials into one another, which consequently results in fatigue wear, surface roughness, tribocorrosion and seizing up of critical parts. The aim of the review is to analyze and summarizes the issue of galling, concurrently it also deals with the novel and economical mitigation method i.e. use of fluorine based coatings e.g. PTFE, owing to their lowest friction coefficient from 0.02 to 0.2 among other solids, high stiffness, high thermal stability and non-adherent characteristics that augments the mechanical and tribological properties and concurrently protect against hostile environments that eventually upsurges the life of components.

“…Polymers, such as polysulfone, poly(ether sulfone), polyurethane, poly(vinylidene fluoride) (PVDF), polystyrene, and poly(vinyl chloride), can applied as hydrophobic nanofibrous membranes by the electrospinning method. Among, PVDF polymers are a good choice for applications in membrane distillation and filtration because of their good mechanical and thermal properties; they are also intrinsically hydrophobic and have a water contact angle near 85°, as revealed in their smooth films …”

Superhydrophobic and superoleophilic functionalized electrospun poly(vinylidene fluoride) (PVDF) membranes with water repellence, breathability, and oil‐sorption and oil–water separation properties were achieved with a combination of an electrospinning technique and the chemical vapor deposition of dichlorodimethyl silane. The samples were laterally characterized by scanning electron microscopy, atomic force microscopy, water contact angle measurement, and Fourier transform infrared spectroscopy. The maximum water contact angle value was 152.0 ± 2.5° for the PVDF nanofibrous membranes with 500 μL of deposited silane (PMS2) obtained under certain conditions. The PMS2 membranes showed 100.0, 93.7, 23.3, 35.0, and 100.0% separation efficiencies for n‐hexane, kerosene, crude oil, frying oil, and toluene, respectively. The understudy membrane exhibited reasonable waterproofness and remarkable breathability (water vapor transition rate = 215.21 g/m2.h). Moreover, the superhydrophobic and superoleophilic nanofibrous membranes also showed good reusability, stability, moderate water‐repellent properties, breathability, antifouling properties, and oil–water separation ability after several cycles. These properties confirmed potential in feasible applications, including protective cloths and in the purification of oil‐polluted water. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.
