“…In addition to this, some methods and materials of soft lithography [14,15,24], colloidal templating [25], electrodeposition [18,[26][27][28], electrospray [29], layer-by-layer deposition [30], electrowetting [31,32], superhydrophobic silicon nanofilaments [33], nanoporous cellulose lauroyl ester [34], and porous polyelectrolyte multilayer [35] have been successfully employed as the holding structures for lubricant infiltration, but they are also plagued with some problems, such as process complexity and large requirement of time and money. Herein, we prepared transparent self-cleaning SLIPS with breath figure patterns (BFPs) formed on the glass substrates based on our previous work regarding BFPs preparation using an enhanced breath figure method (BFM) [36].…”

“…Several studies have shown that the retention of oil on the surface resisted ingress of water or organic liquid [29,30]. The marine industry has employed oil impregnation into the porous structure to prevent corrosion of the material in a marine environment using high purity aluminum, 5000 series aluminum and low alloy steel [31][32][33][34]. Some studies have indicated that the oil impregnated nanoporous oxide layer is likely to lose the oil under a dynamic environment [35].…”

This study investigated the corrosion resistance of oil impregnated anodic aluminum oxide (AAO) surfaces of aluminum 7075 for subsea application. Although aluminum 7075 has high strength, it is scarcely used in the subsea industry because of its corrosion issue. Some treatment of aluminum 7075 is required for subsea application. In this study not only a plate shape but also a cylindrical shape were investigated because a cylindrical shape is frequently used in the subsea industry for electronic device housing. Contact angles of bare aluminum and oil impregnated AAO surfaces of aluminum 7075 were measured after a salt spray test and a pressure test. The results showed that the contact angle of bare aluminum was considerably decreased after the salt spray test, whereas the oil impregnated AAO surface presented a relatively high contact angle after the salt spray test and the pressure test. These results showed that the corrosion resistance of aluminum 7075 could be enhanced by oil impregnation on the AAO surface, and thus can be utilized in the subsea industry.

“…Impregnated oil not only minimizes the direct contact of water with the solid structures but also has fluidity owing to the nature of oil, and thus can allow unique self‐cleaning and healing properties . In addition, the impregnation of oil into the surface porous structures including the AAO has been employed to prevent the corrosion of metallic materials (e.g., steel and aluminum) in marine environments …”

The major drawback of current passivation techniques for preventing corrosion is the lack of ability to withstand any external damages or local defects. In this study, oil‐impregnated nanoporous anodic aluminum oxide (AAO) layers are investigated to overcome such limitations and thus advance corrosion protection. By completely filling hydrophobized nanopores with oil via a solvent exchange method, a highly water‐repellent surface that prevents the penetration of corrosive media into the AAO layer and hence the corrosion of aluminum is achieved. The impregnation of oil into the hydrophobic nanoporous AAO layer enhances the corrosion resistance of an AAO layer by two and four orders of magnitude compared to that of a hydrophobic (i.e., air‐entrained) and a bare (hydrophilic) AAO, respectively. In the presence of local defects, the oil impregnated within the hydrophobic nanoporous AAO layer naturally permeates into the defects and ultimately inhibits the exposure of the aluminum surface to corrosive media. Whereas the corrosion current density of the air‐entrained hydrophobic AAO layer increases by more than 30 times after cracks, that of the oil‐impregnated AAO layer increases by no more than 4 times, showing superior anticorrosion property even after there are cracks, owing to the effective self‐healing capability.
