“…Such porous surface morphology is uniformly formed on the entire aluminum surface, and the size of pits and nanopores were highly reproducible under the present condition. The hierarchically micro‐/nanoporous surface thus obtained is superhydrophobic and superoleophobic, as reported previously …”

“…The hierarchically porous surfaces with fluoroalkyl monolayer coating are superoleophobic even for low‐surface‐tension liquids . Using the nanopores as reservoirs of an organic healing agent, repeatable self‐healing of superoleophobicity is also demonstrated . Thus, the hierarchically porous aluminum substrate thus prepared will be suitable also for SLIPSs.…”

Slippery liquid‐infused porous surfaces (SLIPS) have been receiving increased attention. Fluorinated compounds have been used to prepare SLIPS, but because of bioaccumulation and ecological impact of perfluoroalkyl building blocks, the fluorine‐free SLIPS (F‐free SLIPS) system is preferable for practical applications. Herein, SLIPS are prepared from a hierarchically porous aluminum substrate, tetradecylphosphonic acid monolayer coating, and silicone lubricant oil. The several properties of the SLIPS, including durability against lubricant loss, ice adhesion, and corrosion resistance, are compared with those with a fluoroalkyl monolayer coating and fluorinated lubricant oil. The findings demonstrate that the F‐free SLIPS show higher durability against the removal of lubricant in air and also in water. Both fluorinated SLIPS (F‐SLIPS) and F‐free SLIPS samples exhibit extremely reduced ice adhesion compared with superhydrophobic surfaces obtained using the same hierarchically porous aluminum substrate with fluorinated or fluorine‐free monolayer coating. The SLIPS samples have very high corrosion resistance in NaCl solution but not in alkaline solution. The solution‐dependent corrosion resistance is discussed in terms of the stability of monolayer coating.

“…According to the nature of the damages, superwetting surfaces have been designed to self-heal against particular chemical, physical, or both damages. Various methods have been investigated to prepare self-healing superwettibility, such as wet chemical coating, ,,− spraying, spin, or dip-coating, − chemical vapor deposition, − and layer-by-layer depositions. , Cross-linking, surface modification, and grafting could be involved.…”

The research on superwetting surfaces with a self-healing function against various damages has progressed rapidly in the recent decade. They are expected to be an effective approach to increasing the durability and application robustness of superwetting materials. Various methods and material systems have been developed to prepare selfhealing superwetting surfaces, some of which mimic natural superwetting surfaces. However, they still face challenges, such as being workable only for specific damages, external stimulation to trigger the healing process, and poor self-healing ability in the water, marine, or biological systems. There is a lack of fundamental understanding as well. This article comprehensively reviews self-healing superwetting surfaces, including their fabrication strategies, essential rules for materials design, and self-healing properties. Self-healing triggered by different external stimuli is summarized. The potential applications of self-healing superwetting surfaces are highlighted. This article consists of four main sections: (1) the functional surfaces with various superwetting properties, (2) natural self-healing superwetting surfaces (i.e., plants, insects, and creatures) and their healing mechanism, (3) recent research development in various self-healing superwetting surfaces, their preparation, wetting properties in the air or liquid media, and healing mechanism, and (4) the prospects including existing challenges, our views and potential solutions to the challenges, and future research directions.

“…Additionally, once the surface was subjected to mechanical or chemical damage, the low surface energy 1 H ,1 H ,2 H ,2 H ‐perfluorodecyltriethoxysilane (PFDTES) molecular that confined in the coating would migrate to the damaged interface, which facilitated the oleophobic performance perfectly healed. Very recently, Habazaki and co‐workers fabricated self‐healing and oleophobic coatings by infiltration of fluoroalkyl silane (FAS) into a hierarchically porous aluminum surface, as observed in Figure 15i. The FAS‐infiltrated porous surfaces were able to recover the damages caused by oxygen plasma treatment in the normal condition atmosphere or room temperature, and this healing process was repeatable (Figure 15j–o).…”

In the past few decades, the self‐healing surface materials with durable mechanical, functional, and structural properties have attracted enormous research interests, which exhibit great potential in energy conversion devices, sensors, electronic skins, superhydrophobic fabrics, medical/biological hydrogel, and a protective coating. Despite the remarkable progresses achieved in the self‐healing surface, the systematic and overall reviews that focus on self‐healing surface materials are still lacking and in urgent need. Herein, the recent advances in the development of self‐healing surface materials are summarized. The surface damage forms that composed of cracks, scratches, punctures, and surface wear, are systematically reviewed. The self‐healing mechanism and methods at interface are then introduced to briefly explain the basic design principle. The recent developments of functional surfaces including superhydrophobic, oleophobic, antifogging, anti‐icing, antibiofouling, and anticorrosion surfaces with self‐healing functions are further discussed. Finally, the contemporary challenges, and the future perspectives that motivate are proposed to create more innovative self‐healing materials for diverse fields.
