initially hydrophilic‚ then introducing roughness to that surface will make it even more hydrophilic. Wetting (hydrophilic property) is characterized by the contact angle of a surface and occurs when the surfaces has a contact angle of θ < 90°‚ whereas if the surface is hydrophobic‚ the value of the contact angle is greater than 90°. The contact angle depends on several factors‚ such as roughness‚ the manner of surface preparation‚ and surface cleanliness (Adamson‚ 1990; Israelachvili‚ 1992; Bhushan
