TL;DR: In this paper, the surface tension and surface tension of polymers were calculated from contact angles by the Harmonic-Mean and Geometric-means methods. But the results of the analysis of the contact angles were limited.

TL;DR: In this article, the roughness of a solid is discussed, and it is shown that both the apparent contact angle and the contact angle hysteresis can be dramatically affected by the presence of roughness.
Abstract: We discuss in this review how the roughness of a solid impacts its wettability. We see in particular that both the apparent contact angle and the contact angle hysteresis can be dramatically affected by the presence of roughness. Owing to the development of refined methods for setting very well-controlled micro- or nanotextures on a solid, these effects are being exploited to induce novel wetting properties, such as spontaneous filmification, superhydrophobicity, superoleophobicity, and interfacial slip, that could not be achieved without roughness.

TL;DR: In this paper, the free energy of formation of emulsion drops covered with close-packed monolayers of monodisperse spherical particles was investigated and the possibility of preparing novel solid materials by evaporating solid-stabilised emulsions is also proposed.
