Hydrophobic to superhydrophobic surface modification using impacting particulate sprays

Non‐destructive production of natural environment‐adaptive super‐hydrophobic hierarchical ceramic surface on a steel substrate

“…2a and c. It means that the surface roughening by the abrasive blasting improves the CA. A similar phenomenon was reported in the literature [25,26]. Actually, this abrasive blasting approach can be used for the large steel structures such as oil/gas pipes.…”

Liquid Body Formation from a Semispherical Superhydrophobic Well on a Small Incline

“…While superhydrophobic (SH) surfaces are found in nature in the form of lotus and rice leaves and butterfly wings, , they can now be fabricated through a variety of methods. − As they typically possess low surface energies, SH substrates are useful in applications that require self-cleaning. In microfluidics, devices that apply discrete independently controllable sample volumes are now increasingly preferred as they permit the microfluidic function to assume a set of basic repeated operations, whereby one unit of fluid can be moved over one unit of distance, thus facilitating the use of hierarchical and modular approaches that then make up flexible and scalable system architectures with high fault tolerance capabilities.…”

Glycerol–water sessile drop elongation on PTFE inclines in relation to biochemical applications

“…This relationship is likely governed by the capacity of the surface to retain bubbles on the surface. Surfaces that are inherently hydrophobic, such as PTFE, if treated to have substantial micro and nanostructures, have the capacity to be highly non-wetting and exhibit very high equilibrium contact angles (>120 • ) to render them superhydrophobic (SH) [20,21]. When immersed in water, SH surfaces have been shown to develop a stable thin film of air called a plastron [22,23].…”
