The measurement of the equilibrium contact angle of a small droplet of fluid partially wetting a flat solid surface provides information on the solid-liquid interfacial energy. However, if the spreading power, S = gammaSV - (gammaSL + gammaLV), of the surface is positive the liquid spreads completel

The surface tensions, wetting tensions, contact angles and solid/liquid interfacial tensions of defined siloxanes as well as those of analogous carbosilanes, polysilanes and neopentyl substituted silanes were determined. The wetting experiments were carried out on a glass plate coated with perfluoro
The nature of the surface forces, acting in the wetting films of pentane, hexane and heptane on water and on aqueous NaCl solutions is discussed. It is shown that an important contribution to the surface forces originates from the low solubility of water in short-chain alkanes. The isotherms of wate
