Summary: This study presents a simple and scalable production method for superhydrophobic surfaces and porous materials. The highly hydrophobic CH2/CH3-grafted copper is achieved by exposure to a high-pressure supercritical CO2 + H2O environment, and the hydrophobicity is reinforced by using hierarchical macronanoporous copper. The durable and effective superhydrophobic porous material is successfully utilized for oil-water emulsion separation. Molecular dynamics simulations suggest that the grafting results from a CO2 hydrogenation reaction. The proposed approach may have widespread applications in various fields.

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: Superhydrophobic surfaces with low adhesion and high antiwetting have attracted significant attention for their unique physical characteristics and potential applications. However, designing robust superhydrophobic surfaces with these properties remains a challenge. In this paper, we discuss the important parameters for characterizing the adhesion and antiwetting properties of superhydrophobic surfaces, and highlight the contradiction between low adhesion and high antiwetting. We also review recent progress in the optimal design of superhydrophobic surfaces using chemical modification and physical microstructure design. Additionally, the application of superhydrophobic surfaces for drag reduction is discussed.

Silicones are preferred due to their inherent hydrophobicity and processing ability. Despite the low mechanical stability, it can be improved through rational design. This review provides an overview of silicone-based superhydrophobic surfaces and their applications, serving as inspiration for polymer interfaces and colloid science development.

Summary: A superhydrophobic surface with micro/nanoscale structures was designed by employing facile and low-cost demolding and initiated chemical vapor deposition (iCVD) processes. The achieved micro/nanostructured superhydrophobic surface exhibited a maximum static contact angle of about 170 degrees, a roll-off angle and contact angle hysteresis below 1 degree, ultralow solid/liquid adhesion for water droplets, and maintained excellent superhydrophobicity even after exposure to strongly corrosive substances for 60 hours. This reasonably-designed method provides valuable guidelines for the manufacture of transferable superhydrophobic surfaces and enables potential applications in optoelectronic devices and self-cleaning materials.

Summary: The wetting properties of three different metals (aluminum, copper, and galvanized steel) were studied after being ablated with ultrafast fiber lasers. The surfaces initially exhibited superhydrophilicity, which evolved into hydrophobicity after 30 days in ambient conditions and superhydrophobicity after 6 hours in low-pressure environment, demonstrating the effectiveness of ultrafast laser-surface nanostructuring coupled with vacuum ageing in achieving extreme superhydrophobic states suitable for self-cleaning applications.

Summary: This study developed a new hot pressing process to prepare superhydrophobic surfaces on glass substrate with controllable shape and size. Microstructures were fabricated on a tungsten carbide mold via picosecond laser processing, and then reproduced on glass during the hot embossing process. The superhydrophobic glass surface exhibited a high contact angle and low sliding angle. Various techniques were used to analyze the structures and chemical composition of the surface. The study also demonstrated the temperature resistance, chemical stability, and mechanical stability of the superhydrophobic glass surface.

Summary: In this study, a solvent evaporation-induced self-assembly method was innovatively proposed to produce superhydrophobic surfaces (SHS) with facile prepared, environmentally friendly, and ultrafast ambient temperature curable properties. The surface superhydrophobicity and morphology of the SHS can be readily tuned by varying the spraying concentrations, diisocyanates, solvents, spraying heights, and molecular weight of PDMS. The formation mechanism of the SHS was investigated through small-angle scattering and X-ray photoelectron spectroscopy.

Summary: Thin films of chromel and alumel alloys with thickness less than 100 nm were obtained using the plasma deposition technique FCVA. Quantitative EDS analysis was found to be reliable for these films when substrates with similar atomic numbers to film constituents were used, especially copper. Good consistency between EDS and RBS measurements was observed for both alloys on copper substrates, with EDS analysis being crucial for alumel films due to overlapping peaks in RBS output.
