Slippery liquid-infused porous surface (SLIPS) has received widespread attention in the antifouling field, while its controllability of surface lubricity and durability of lubricant are relatively insufficient. In this study, inspired by the hagfish's defensive behavior of secreting mucus to escape from predators, a smart SLIPS marine antifouling coating is prepared, which possesses responsively switching lubrication modes and self-healing property. The responsive supramolecular interaction between azobenzene (Azo) and α-cyclodextrin (α-CD) is introduced to regulate the lubricity of SLIPS. cis-Azo is converted to trans and combined with α-CD by supramolecular interaction under visible light or heating, driving the shrinkage of polymer chains to squeeze the stored lubricant to the surface. The responsive self-replenishment of lubricant can adjust the surface lubricity to switch antifouling modes between "enhancive" and "normal" smartly, which adapts to different occasions. Moreover, disulfide and hydrogen bonds are introduced to enhance self-healing performance (91.73%). In summary, it has efficient self-cleaning, anti-protein, antibacterial, anti-algae properties, and 180-day real marine field antifouling performance during boom season (the longest antifouling period in real marine field test of reported SLIPS materials), which demonstrates the promising application in neritic sea equipment and other antifouling fields.

“…It can be seen from Figure 6D that the size of the microphase separation on the surfaces of BT54, and BT42 coatings are more conducive to inhibiting the adhesion of Nitzschia closterium (width: 2-3 μm) due to the structure of BT54 (with more obvious depth of the bulge) and BT42 (with more different size distribution). [47][48][49] The increase in water absorption due to the decrease in lipophilic monomers (Figure 5B) also inhibited the adsorption of algae on the coating surface. The BT42 coating had the best performance in inhibiting the adsorption of algae.…”

The poor adhesion of hydrogel antifouling materials on substrates limits their application in marine antifouling. From the perspective of practical application, a lipophilic monomer tackifying strategy is proposed, in which hydrogel coatings can be firmly adhered to substrates very simply. Hydrogel prepolymers containing lipophilic monomers are adhered to the substrate surface after crosslinking, and hydrogel coatings are obtained after drying and absorbing water. The experimental results show that the molar content of lipophilic monomers in the hydrogel reached 42% and can significantly improve its adhesion on the organic substrate. The highly adhesive ability of the hydrogel manifest as its long‐term no‐shedding ability in the experimental results of static seawater immersion panels, dynamic rotating seawater environments (80 revolutions min−1), and testing‐panels in real marine (150 days‐no‐shedding). A powerful supplement for understanding the direct adhesion of hydrogel coatings to the substrate is provided by this strategy. These hydrogels have a good effect on inhibiting the adhesion of proteins and microalgae and show significant antifouling performance in testing‐panels in real marine environments, with great potential for marine antifouling applications.

“…In theory, a hydrophilic material usually has strong hydrogen bond interactions with water molecules, which can induce water molecules to bind intensively with material surfaces, leading to the formation of a hydration layer with the shielding effect. The existence of a hydration layer can make it difficult for bacteria and protein to get close to material surfaces, thus achieving a good anti-fouling property ( Jin et al., 2022 ). Currently, polyethylene glycol (PEG) and zwitterionic polymer are the two most widely used hydrophilic anti-fouling materials ( Venault et al., 2014 ; Lee et al., 2019 ).…”

The balance or dysbiosis of the microbial community is a major factor in maintaining human health or causing disease. The unique microenvironment of the oral cavity provides optimal conditions for colonization and proliferation of microbiota, regulated through complex biological signaling systems and interactions with the host. Once the oral microbiota is out of balance, microorganisms produce virulence factors and metabolites, which will cause dental caries, periodontal disease, etc. Microbial metabolism and host immune response change the local microenvironment in turn and further promote the excessive proliferation of dominant microbes in dysbiosis. As the product of interdisciplinary development of materials science, stomatology, and biomedical engineering, oral biomaterials are playing an increasingly important role in regulating the balance of the oral microbiome and treating oral diseases. In this perspective, we discuss the mechanisms underlying the pathogenesis of oral microbiota dysbiosis and introduce emerging materials focusing on oral microbiota dysbiosis in recent years, including inorganic materials, organic materials, and some biomolecules. In addition, the limitations of the current study and possible research trends are also summarized. It is hoped that this review can provide reference and enlightenment for subsequent research on effective treatment strategies for diseases related to oral microbiota dysbiosis.
