“…Here, the μm thick porous oxide layer was obtained with nanometer-scale porosity. We and others demonstrated excellent repellent characteristics of SLIPS substrates prepared by various techniques; however, these characteristics were mainly obtained on plain, undamaged SLIPS substrates. ,,,,,,− Here, SLIPS substrates were damaged similarly to LISS substrates and then examined for their anti-biofouling characteristics; the results are summarized in Figure d,j,k. As shown, the damaged SLIPS substrates demonstrate an intact morphology, that is, there was no detachment or delamination of the oxide porous layer, while only a smashed area indicates that the oxide layer adheres well to the underlying metallic substrate.…”

Wetting of surfaces plays a vital role in many biological and industrial processes. There are several phenomena closely related to wetting such as biofouling and corrosion that cause the deterioration of materials, while the efforts to prevent the degradation of surface functionality have spread over several millennia. Antifouling coatings have been developed to prevent/delay both corrosion and biofouling, but the problems remain unsolved, influencing the everyday life of the modern society in terms of safety and expenses. In this study, liquid-infused slippery surfaces (LISSs), a recently developed nontoxic repellent technology, that is, a flat variation of omniphobic slippery liquid-infused porous surfaces (SLIPSs), were studied for their anti-corrosion and marine anti-biofouling characteristics on metallic substrates under damaged and plain undamaged conditions. Austenitic stainless steel was chosen as a model due to its wide application in aquatic environments. Our LISS coating effectively prevents biofouling adhesion and decays corrosion of metallic surfaces even if they are severely damaged. The mechanically robust LISS reported in this study significantly extends the SLIPS technology, prompting their application in the marine environment due to the synergy between the facile fabrication process, rapid binding kinetics, nontoxic, ecofriendly, and low-cost applied materials together with excellent repellent characteristics.

“…Previous work suggests that the lubricant infiltration capacities on textured surfaces may be affected by the dimensions of the designed surface textures [18][19][20]. Notably, the infiltration capacities of the lubricant are the amount of lubrication that can penetrate and be retained in the surface textures (after dipping) before the friction tests in this work.…”

Surface texturing is recognized as an effective solution for reducing friction on stainless-steel contact interfaces. Previous studies mainly focused on the influence of the texture parameters and lubricant-film depths on their tribology performances. Notably, whether the lubricant can penetrate texture and the lubricant infiltration capacity may significantly affect the tribology performances of the contact interfaces. They have been rarely considered, which may cause some well-designed textures to fail to perform their roles and be abandoned. Herein, a novel lubricant model is developed to explore the tribology performances of the contact interfaces with different lubricant infiltration capacities in textures and the influence factors of the lubricant infiltration capacities. Textured surfaces with different dimensions are fabricated by the femtosecond laser to explore the effects of the texture dimensions on the lubricant infiltration capacities. The results indicate that texture width, depth and lubricant viscosity could significantly affect the lubricant infiltration capacities. Moreover, the results indicate that the lubricant infiltration capacity would significantly affect the tribology performances of the contact interfaces. This work indicates that the impact of the lubricant infiltration should be considered in texture design. This work can be widely used to guide the texture design applied in plenty of fields.

On this basis, two theoretical models appeared to the world. In 1936, Wenzel added a surface roughness factor "r" to Young's equations. [7] In 1944, Cassie and Baxter showed that the composite interface of solid and air can affect the superhydrophobicity. [8] Since then, the theory and analysis of surface has aroused enormous interest among scientists and researchers. In 1997, Barthlott and Neinhuis proposed the "lotus effect," [9] which is a hydrophobic and self-cleaning effect originated from the hierarchical structure of lotus leaves. A flurry of research on superhydrophobic surfaces came after that. Gradually, research on fabrication of surfaces with special wetting property became popular.The commonly used materials for daily applications contain textiles, glass, metal, and their alloys whose surfaces can be protected from being wetted, contaminated, or fouled by water and oil pollutants. Most metal materials will inevitably be oxidized when they encounter common liquid corrosion media, such as water, and the oxide film cannot effectively protect them. If the metal is covered with superhydrophobic surface, the air cushion contained in the micro-nano composite structure on the surface will protect the metal and separate the direct contact between the substrate and the liquid. It makes it difficult for corrosive ions to reach the metal surface, which significantly improves the corrosion resistance of the metal. However, the air cushion is unstable and easily replaced by liquid under external pressure and high temperature, losing its superhydrophobicity and corroded by liquid.At present, there are two main research directions of liquid repelling surfaces: Cassie-Baxter water contact state surfaces and lubricant-liquid contact state surfaces. The Cassie-Baxter contact surface designation was inspired by lotus leaves, butterfly wings and Inaba, mainly included superamphiphobic, superhydrophobic, and superoleophobic surfaces. These artificial surfaces can be combinate by low surface energy substance modification and micro-nano structures. Besides, with the inspiration of Nepenthes, lubricant-liquid contact state surfaces are designed. In 2011, Joanna Aizenberg of Harvard University and her colleagues first introduced "slippery liquid infused porous surface" (SLIPS)-that each consist of a film of lubricating liquid locked in place by a micro/nano porous substrate. [10] Compared with superhydrophobic surface, its air layer is replaced by immiscible liquid layer, which provides a more Slippery liquid infused porous surface (SLIPS) inspired by the microstructure of carnivorous Nepenthes has the potential to be used in a wide range of fields, including nautical, industrial, medical, etc. Due to their excellent optical transparency, self-healing after mechanical injury and controllable wetting properties, SLIPS has attracted extensive research interest. With appropriate lubricants, sufficient performance will be armed to the surface so as to adapt for further requirements. In this review, the first part focuses on the b...
