A fluidic property similar to surface tension but referring to the affinity of the liquid to a solid surface. This "wetting" property is frequently measured by an instrument called a goniometer which measures the contact angle of the liquid with the surface.
at the liquid-liquid interface between two dissimilar liquids (eg aqueous and organic phases), there will be interactions between molecules of different type. The interfacial tension between the two phases arises due to the attractive forces between the molecules in the different fluids.
important thermodynamic material parameter used for the characterization of phase boundaries; denotes the amount of work necessary to form a new piece of interface between two phases (SI units: mN/m and mJ/m2)
A measure of the molecular forces existing at the boundary between two phases. It is expressed in dynes/cm. Liquids with low interfacial tension are more easily emulsified.
the energy per unit area present at the boundary of two immiscible liquids, usually expressed in dynes/cm.
The strength of the film separating two immiscible fluids (e.g. oil and water) measured in dynes per, or millidynes per centimeter.
The difference in surface tension between two media.
