• created, and in this article the influence of structure on drag reduction efficiency is reviewed. Biomimetic-inspired oleophobic surfaces can be used to prevent contamination of the underwater parts of ships by biological and organic contaminants, including oil. The article also reviews the wetting

• that can be used against marine ship fouling [17]. Jung and Bhushan [20] proposed a model for predicting the oleophobic/philic nature of surfaces and showed how the water and oil droplets in three phase interfaces influence the wetting behavior on micropatterned surfaces with varying pitch values as

• applications. In this section, we discuss a model for predicting the oleophobic/philic nature and experimental measurements of the wetting properties of the surfaces. Modeling of contact angle for various interfaces If a water droplet is placed on a solid surface in air, the solid–air and water–air interfaces

• cases are considered: First, the relative strength of the interactions of the substrate is assumed to be identical for both elements. In this case, the parameters determine the wetting angle of the particle in equilibrium with the substrate. Second, it is assumed that only Pt has a significant binding

In addition to wetting, the parameters then provide a driving force for segregation of Pt at the interface to the substrate which prefers a c-axis orientation of the L10 structure perpendicular to the substrate.

Compared to surface potential studies the use of dC/dZ measurements was relatively limited by studies of organic layers [23] and water
