ABSTRACT

ABSTRACT

Static contact angle of a water drop of untreated (a) and (b) treated limestone by a water repellent product. Superhydrophobic surfaces exhibit certain wetting characteristics originating from very high static contact angles (>150°) and very small values of contact angle hysteresis (<10º) ( 91, 100, 101 ).
