“…At present, organic silicon materials are widely used as antifouling surfaces because of their low-surface-energy characteristics, which can efficiently interrupt the attachment of microorganisms. Moreover, nontoxic organic silicon coatings are environmentally friendly, which can prevent pollution caused by nontarget organisms poisoning in the ocean. − As a result, scientists employed silicone materials for the fabrication of biomimetic antifouling textured surfaces. Referred to the biomimetic design, these textured surfaces could better show excellent antifouling and drag reduction effects. , This means to achieve the purpose of antifouling by changing the solid surface textures reduces the use of chemical reagents to some extent.…”

The nature always offers amazing inspiration, where it is highly desirable to endow coatings on marine equipment with powerful functions. An excellent example is slippery zone of Nepenthes pitcher, which possesses novel liquid-repellent and selfcleaning performance. Therefore, this study presents an efficient fabrication method to prepare a novel coating. The coatings were fabricated by designing biomimetic textures extracted from the lunate bodies of slippery zone on polydimethylsiloxane (PDMS) and then grafting Dictyophora indusiata polysaccharide (DIP) modifier. The as-prepared slippery coatings exhibited outstanding antifouling properties against kinds of daily life pollutants such as Chlorella and coffee. This synergistic strategy was proposed combined with environmentally friendly modifier grafting and heterogeneous microstructure on the surface to broaden new probabilities for manufacturing slippery coatings with incredible protective functionality.

The conventional Slippery Liquid Infused Porous Surface (SLIPS) encounters challenges such as silicone oil leakage and complex manufacturing of rough substrate structures. Thus, it is crucial to develop a lubricant that is highly adaptable and less prone to loss for surface structures; a temperature‐controlled method of infusing oleogel into a superhydrophobic surface (SHS) is presented in this paper. This approach draws inspiration from the characteristics of Nepenthes pitcher plant structures, albeit without the need for intricate pore‐making or nanowire structures. It is demonstrated that this resulting surface has exceptional fog harvesting capability, with a fog harvesting efficiency of 0.3222 g cm−2 min−1, which is twice as high as that of the laser aluminum (Al) sheet (0.1553 g cm−2 min−1). Moreover, the surface exhibits remarkable anti‐icing properties, significantly prolonging the icing time by 21‐fold compared to the pure Al sheet while maintaining a minimal ice adhesion force of only 0.16 N. Additionally, the surface showcases excellent antifouling performance, because contaminated droplets readily slide off without leaving residue. The environmentally friendly and straightforward preparation process ensures that it is suitable for large‐scale industrial applications.
