Summary: In this study, a cardiopulmonary bypass tube with good superhydrophobicity and blood repellency was created. The superhydrophobic-treated tube showed a clotting time increase of 157% compared to the bare PVC tube, and a decrease of 32% and 74% in protein and platelet adsorption, respectively. The study also provided an explanation for the anti-platelet adsorption mechanism of superhydrophobic coatings.

Summary: This study addresses the issue of membrane fouling and low separation efficiency in oil/water separation by implementing a superhydrophobic coating on the surface of a ceramic membrane. By growing needle-shaped alumina (Al2O3) and impregnating a polydimethylsiloxane (PDMS) coating, a durable superhydrophobic-superoleophilic composite coating was fabricated. Characterization techniques were used to analyze the microstructure, surface composition, and surface characteristics of the modified CM. Mechanical, chemical, and thermal stability tests were conducted, as well as evaluation of the separation performance, anti-pollution property, and reusability. The results showed that the modified CM exhibited excellent superhydrophobicity with high separation efficiency.

Summary: This study presents a new method to create durable superhydrophobic porous materials with magnetic properties that can repel hot water. Carbon fibers in a carbon felt are coated with a Ni-Co alloy layer using galvanostatic electrodeposition, resulting in a surface with nano-protrusions and a thickness of about 2 μm. After thermal annealing, the surface becomes increasingly hydrophobic and achieves superhydrophobicity after 12 hours. The prepared carbon felt also demonstrates robust superhydrophobicity under high compression force and cyclic abrasion, making it suitable for various applications, including oil/water separation in complex structures.

Summary: In 1948, Cassie proposed an equation for the wetting of a smooth, heterogeneous surface. This equation uses weighted averages based on the fractional surface areas and cosines of contact angles to predict the contact angle of a droplet on a composite surface. The equation has proven fundamental in understanding the wetting of superhydrophobic and superoleophobic surfaces. However, little attention has been given to the complete wetting of one surface component.

Summary: Over the past few decades, superhydrophobic coatings (SHCs) have attracted scientists and researchers due to their wide range of applications in various fields. Different techniques have been attempted to fabricate SHCs, but most of them have limitations. The hot embossing (HE) technique, however, shows great potential in replicating micro-nanofeatures on polymeric surfaces. This review article focuses on the recent advancements in HE-operated polymeric SHCs and their applications.

Summary: Experimental and molecular dynamics simulation studies were used to investigate the hydrophilicity of substrate surfaces and hydrophobicity of as-prepared surfaces at the molecular level. The superhydrophobicity of the as-prepared surfaces was attributed to fluorinated compositions and microstructures. The decreased van der Waals interaction with water molecules contributed to the hydrophobicity of the fluorinated surfaces on aluminum substrates.
