In his opening remarks at the first symposium in this series Professor Robert Good pointed out that Galileo in the 17 century was quite likely the first investigator to observe contact angle behavior with his experiment of floating a thin gold leaf on top of a water surface. Since that time contact angle measurements have found wide application as a method for determining the energetics of surfaces. This, in turn, has a profound effect on the wettability and adhesion of liquids and coatings to surfaces.read more

Purity of the sacred lotus, or escape from contamination in biological surfaces
TL;DR: It is shown here for the first time that the interdependence between surface roughness, reduced particle adhesion and water repellency is the keystone in the self-cleaning mechanism of many biological surfaces.

TL;DR: It is shown how a third factor, re-entrant surface curvature, in conjunction with chemical composition and roughened texture, can be used to design surfaces that display extreme resistance to wetting from a number of liquids with low surface tension, including alkanes such as decane and octane.

Self-cleaning surfaces - virtual realities
TL;DR: Key advances in the understanding and fabrication of surfaces with controlled wetting properties are about to make the dream of a contamination-free (or 'no-clean') surface come true.

Natural and biomimetic artificial surfaces for superhydrophobicity, self-cleaning, low adhesion, and drag reduction
Bharat Bhushan,Yong Chae Jung +1 more
TL;DR: In this paper, the theoretical mechanisms of the wetting of rough surfaces are presented followed by the characterization of natural leaf surfaces and a comprehensive review is presented on artificial super-hydrophobic surfaces fabricated using various fabrication techniques and the influence of micro-, nano-and hierarchical structures on superhydrophobicity, self-cleaning, low adhesion, and drag reduction.
