Summary: A superhydrophobic surface with good robustness and efficient water collecting performance was successfully fabricated through structuring multilevel microstructures. The surface exhibited great water repellency, chemical stability, and maintained water proofing property even after cyclical abrasion. The water harvesting efficiency was higher than those of the previously reported surfaces, making it a potentially crucial solution for water collection in fog/mist environments.

Summary: This study developed biocompatible nanofibrous mats with antiadhesive surfaces inspired by the lotus leaf nanostructure. A combination of needleless electrospraying and electrospinning technology was used to mimic the structure, and the surface hydrophobicity was enhanced by cold plasma modification using a chemical vapor deposition method. The material's morphology, wettability, and chemical composition were observed over a period of six months, and cytocompatibility and antiadhesive behavior were confirmed through in vitro tests.

Summary: In this study, a simple method to achieve superhydrophobicity on various substrate surfaces is proposed. By using femtosecond laser direct processing, grooves and protrusions are constructed on substrates to form a protective layer, followed by scanning with polytetrafluoroethylene (PTFE) to achieve superhydrophobicity. This method can achieve robust superhydrophobic surfaces with excellent anti-friction performance on different substrates.

Summary: In this study, superhydrophobic polylactic acid (PLA) surfaces with microstructured pillars were prepared using hot pressing and chemical vapor deposition methods. The wettability and morphology of the PLA patterns were investigated. The results showed that silane coatings containing a fluorine atom could significantly increase the water contact angle of the PLA surfaces, and the coated patterns exhibited excellent resistance and stability.

Summary: Frequent discharge of oily wastewater in industrial or daily life not only wastes oil resources and harms the environment, but using functional sponge materials can effectively treat and recycle these wastewaters. A composite sponge with hierarchical structure, prepared by modifying commercial polyurethane sponge with copper terephthalate and polydimethylsiloxane, shows superior properties such as good superhydrophobicity and mechanical stability, making it ideal for oil adsorption and separation.

Summary: This study presents a controllable and scalable fabrication approach for superhydrophobic hierarchical structures and demonstrates their excellent ability in water energy harvesting. The method combines multiple photolithography and micromolding processes to accurately regulate the diameters and center distances of two-level micropillars. The fabricated hierarchical structures possess advantages such as structure control, large scale, high accuracy, and high consistency. The structures show a larger contact angle than single-level structures, achieving superhydrophobicity. Furthermore, when applied to water-solid contact triboelectric nanogenerators, the hierarchical structures exhibit superior water energy harvesting ability compared to flat films and single-level structures due to enhanced friction area and superhydrophobic property.
