wettability

[‚wed·ə′bil·əd·ē]
(chemistry)
The ability of any solid surface to be wetted when in contact with a liquid; that is, the surface tension of the liquid is reduced so that the liquid spreads over the surface.

In addition to the two wettability alteration mechanisms (crude oil insolubles precipitation and ionic interaction in brine) mentioned above, the surface energy (oil-water interfacial tension) in oil/brine systems, as can be seen from Young's equation (Equation 1), also could affect wetting and contact angles.
Crustaceans secrete waxes onto their cuticles, reducing cuticular wettability and possibly making it more difficult for epibionts to adhere (Becker et al.
