Summary: In this study, a biomimetic hydrophobic PMMA coating was fabricated through the nano-casting technique. The coating demonstrated a surface morphology with micron-sized papillae and nano-scaled creases, converting the hydrophilic PMMA surface to a hydrophobic one. The coating effectively inhibited bacterial attachment and delayed the formation of biofilm, showing promising long-term anti-biofilm performance.

Summary: Superhydrophobic coatings with unique properties such as self-cleaning and staying dry have recently emerged in industrial and consumer markets. The stochastic nature of coating components can affect the uniformity of water repellency, and traditional contact angle goniometry may not provide accurate quantification of wetting properties. The study demonstrates that highly sensitive force-based methods can offer advantages in quantifying microscale heterogeneity in superhydrophobic coatings.

Summary: This article discusses the importance of wetting properties in the formation, growth, and agglomeration of clathrate hydrates, and proposes that changes in surface morphology are responsible for the variation in reported contact angles. Due to experimental limitations, the authors employ molecular dynamics simulations to validate their hypothesis and achieve agreement with experimental observations. The author's research helps interpret adhesion force measurements and provides a microscopic tool for understanding the agglomeration of hydrate particles.

Summary: This study investigates the influence of contact angle (CA) and contact angle hysteresis (CAH) on humid air condensation and reveals their different roles in different stages of the condensation cycle. The findings show that increasing CAH has a negative effect on condensation heat transfer, while the impact of changing CA varies. Lower CAH values have a greater impact on enhancing condensation heat transfer, and increasing CAH has a more significant effect on hydrophobic surfaces than on hydrophilic surfaces. Additionally, decreasing CAH has a more pronounced effect on improving condensation heat transfer than increasing CA.

Summary: Fast removal of water drops from solid surfaces is important in many applications. The reduction in lateral adhesion of water drops on PDMS brush surfaces after exposure to various organic vapors was reported and attributed to the physisorption of vapor and swelling of the PDMS brushes. Contact angles of water drops on three hydrophobic surfaces in different vapors are measured to determine the contribution of vapor adsorption and change in interfacial tensions on drop adhesion. The findings show that vapor-induced change in interfacial tensions can explain the decrease in contact angles, while vapor adsorption into PDMS surfaces forms a lubricating layer, reducing contact angle hysteresis.

Summary: This study establishes a numerical model to investigate the contact behavior between a smooth sphere and a nanoscale rough surface with viscoelastic materials. The research shows that viscoelasticity significantly increases the maximum contact area and pull-off force at low approach speeds, but can be ignored at high speeds. Additionally, the variations of maximum contact area and pull-off force are not consistent with contact position and surface parameters.

Summary: In this study, suitable surface treatments were investigated to enhance the adhesion of ultra-high molecular weight polyethylene (UHMWPE) prepegs with dissimilar materials by reducing the contact angle. Plasma treatment and acid treatment were studied separately as well as their synergistic effect. The effectiveness of this study was validated by measuring the contact angle and adhesive shear strength of the treated composites. SEM and XPS were also used to examine the morphology of the interface. It was observed that plasma-treated samples exhibited increased wettability and significantly reduced contact angle, which was confirmed by the shear strength results. The synergistic effect did not yield better results than either of the solitary treatments.

Summary: The contact angles of water and various organic liquids on native and acetylated cellulose were calculated using molecular dynamics simulations. The wetting behavior was found to be influenced by the liquid surface tension. Acetylation decreased the work of adhesion to most liquids, including nonpolar ones, while others were unaffected. Water showed the highest affinity to both native and acetylated cellulose. These findings have implications for liquid infiltration of nanocellulose networks and the interaction between cellulose and different liquids.
