WebFUNDAMENTALS OF WETTABILITY Wettability describes the preference of a solid to be in contact with one fluid rather than another. A drop of a preferentially wetting fluid will displace another fluid; at the extreme it will spread over the entire surface. WebJan 1, 2024 · Fundamentals of w ettability. If the contact angle is above 150°and a roll-off angle less than below 5° it is known as superhydrophobic surface. Whereas surface with the contact angle below 90° is known as hydrophilic surface. The relationship of contact angle with the states of the surface is shown in Fig. 2.
