wettability
The state or condition of being wettable, or the
relative affinity of liquid for the surface of a
solid. such as the affinity of water for paper or
leather. Wettability increases directly with
increasing affinity, as measured by the contact
angle formed between the liquid and the solid.
This increases from non-wettability at an angle
greater than 90° to complete wettability
when the contact angle is 0°. (17 )
