“…These problems make it impossible to protect SLIPS from corrosion in the biomedical field. Inoue et al 141 considered bioaccumulation and the ecological impact of perfluoroalkyl. They selected silicone lubricants for the construction of fluorine-free SLIPS (F-free SLIPS) systems.…”

“…Despite the potential environmental hazards and high costs of fluorinated oils, they are widely used in the literature as lubricants in SLIPS due to their advantageous properties, such as a wide range of viscosity and superior durability compared to other oils. However, Inoue et al [161] have introduced an alternative solution with the development of fluorinefree SLIPS (F-free SLIPS). These F-free SLIPS are composed of a porous alumina substrate coated with hydrophobic alkyl phosphonic acid and infused with silicone oil, exhibiting greater durability than their fluorinated counterparts.…”

Durability of Slippery Liquid-Infused Surfaces: Challenges and Advances

Slippery liquid-infused porous surfaces (SLIPS) have emerged as a unique approach to creating surfaces that can resist fouling when placed in contact with aqueous media, organic fluids, or biological organisms. These surfaces are composed of essentially two components: a liquid lubricant that is locked within the protrusions of a textured solid due to capillarity. Drops, immiscible to the lubricant, exhibit high mobility and very-low-contact-angle hysteresis when placed on such surfaces. Moreover, these surfaces are shown to resist adhesion to a wide range of fluids, can withstand high pressure, and are able to self-clean. Due to these remarkable properties, SLIPS are considered a promising candidate for applications such as designing anti-fouling and anti-corrosion surfaces, drag reduction, and fluid manipulation. These collective properties, however, are only available as long as the lubricant remains infused within the surface protrusions. A number of mechanisms can drive the depletion of the lubricant from the interior of the texture, leading to the loss of functionality of SLIPS. Lubricant depletion is one challenge that is hindering the real-world application of these surfaces. This review mainly focuses on the studies conducted in the context of enhancing the lubricant retention abilities of SLIPS. In addition, a concise introduction of wetting transitions on structured as well as liquid-infused surfaces is given. We also discuss, briefly, the mechanisms that are responsible for lubricant depletion.

“…SLIPS lubricants can effectively isolate the corrosion of the substrate by the corrosive medium. Especially in the liquid, the lubricants and the aqueous solution are incompatible with each other, and can be stored for a long time, which has a long-term protection potential for the substrate to reduce corrosion [234][235][236] . Table 3 summarizes the innovative technologies applied to the surface processing of magnesium alloys.…”

Thanks to its excellent mechanical properties, magnesium alloys have many potential applications in the aerospace and other fields. However, failure to adequately solve corrosion problems of magnesium alloy becomes one of the factors restricting its wide use in many industrial fields. Inspired by nature, researchers designed and fabricated bio-inspired water-repellent (superhydrophobic and slippery liquid-infused porous surface) surfaces with special wetting properties by exploring the surface microstructures of plants and animals such as lotus leaf and nepenthes pitcher, exhibiting excellent corrosion-resistant performance. This article summarizes the research progress on corrosion resistance of magnesium alloys with bio-inspired water-repellent properties in recent years. It mainly introduces the corrosion reasons, types of corrosion of magnesium alloys, and the preparation of magnesium alloys with bio-inspired water-repellent properties to improve corrosion resistance. In particular, it is widely used and effective to construct water-repellent and anti-corrosion coating on the surface of magnesium alloy by surface treatment. It is hoped that the research in this review can broaden the application range of magnesium alloys and provide a powerful reference for the future research on corrosion resistance of magnesium alloys.
