Double roughness structure mimicking the surface of a lotus leaf was prepared using a newly synthesized diarylethene having a six-membered perfluorocyclohexene ring. The cubic-shaped crystals of the open-ring isomer, with sizes of approximately 7 μm, appeared immediately following solution casting. Upon UV irradiation, each cubic crystal was covered with needle-shaped crystals of the closed-ring isomer to form double roughness structures within 1 h. This structure could bear the continuous impact of water droplets.

“…There are several theoretical, experimental and industrial groups focusing on mimicking bio-inspired artificial superhydrophobic materials offering exciting potentials in self-cleaning, anti-icing, anti-fouling, fluid transport, water collection, biological fluid-repellent surfaces and oil-water separation applications. [5,6,8,[10][11][12][13][14][15][16][17][18][19] In order to construct a mechanically and chemically robust superhydrophobic substrates, it is important to protect hierarchical roughness and low surface energy coating with respect to external stimuli. The impact of water droplet has profound effect on the aspect ratio, roughness and porosity of the superhydrophobic materials.…”

The development of graphene nanoarchitectonics, including their synthesis, surface modification, interfaces, conductivity and porosity, has moved forward rapidly and attracted attention from interdisciplinary research fields. Fluorinated graphene (FG), a rising star and a fascinating member of graphene family has been identified as a promising material for multiple applications, such as sensors, optics, catalysis and self‐cleaning technologies. In this review, we highlight the important aspects of FG pertinent to physiochemical stability and self‐cleaning technologies. We discuss the precise functionalization of FG surfaces with organic functionalities, which are promising for creating high‐performance graphene derivatives. Also, by utilizing the reactivity of few‐layered FG nanosheets, it is possible to develop coatings based on dispersions of functionalized FG inks coupled with porous solids and tubular nanomaterials with super‐wetting functions. The functional groups of the resultant hybrids are connected to innovative substrates including meshes and macroporous sponges that can be useful for super‐wetting containers and oleophilic sorbents. Furthermore, we discuss hydrophobic FG‐porphyrin hybrids with metal coordination and hydrophobicity dependent photoluminescence. Finally, the self‐cleaning action and anti‐corrosion features of FG hybrids are explored, with potential applications in triboelectric nanogenerators and water harvesting. Future development of these materials should focus on new designs, porosity control, batch uniformity, durable self‐cleaning membranes, smart textiles, eco‐compatible coatings and disposability.

“…[35,56] Current technologies are developed to achieve either slippery or sticky behavior by modifying the fabrication techniques and/or material in use, often involving a combination of top-down and bottom-up manufacturing methods. [42,54,[57][58][59][60] Here, we investigate the efficacy of wax crystallization approaches for the fabrication of hydrophobic surfaces exhibiting tuneable slippery or sticky behaviors by controlling the micro/nano-scale crystal structures. We test the idea of organising the nanoscale crystals of a given wax into self-assemblies of different micromorphologies to achieve diverse wetting regimes in chemically identical materials.…”

Across diverse natural surfaces, remarkable interfacial functionalities emerge from micro and nanoscale self‐assemblies of wax components. The chemical composition of the epicuticular wax prescribes the intrinsic crystal morphology and resultant topography of the natural surfaces, dictating their interfacial wetting properties. The potential of regulating the topography of identical wax compositions through various crystallization routes is tested here. Crystallization through solvent evaporation produces diverse topographies with enhanced surface hydrophobicity compared to the slow cooling of the wax melt. Further, the microscale interfacial crystalline structure can be deliberately designed to operate in sticky or slippery hydrophobic regimes through control of the supersaturation level during the crystallization process. While the supersaturation level significantly impacts surface wettability by modulating the microscopic aggregation of rice bran wax crystals, the crystal structure at the molecular scale remains effectively unchanged. The relationships between the supersaturation level, surface topography and hydrophobicity modes, primarily derived for rice bran wax, are qualitatively validated for a wider range of plant‐based waxes. Crystallization of inherently hydrophobic plant‐based waxes from thermodynamically isotropic solutions offers an affordable single‐step approach for the fabrication of biodegradable hydrophobic coatings, applicable to versatile materials and geometries.
