Typically mN/m (which is equivalent to dynes/ cm) is used as the unit for surface and interfacial tension These intermolecular interactions are the same electromagnetic forces that operate between molecules in a gas, liquid, or solid, determining such bulk properties as non-ideal behavior of gases, boiling and sublimation points, and cohesive strength of solids Surface and interfacial tension and their measurement techniques. Interfacial tension is a material property of a fluid-fluid interface whose origins lie in the different attractive intermolecular forces that act in the two fluid phases. This technology note explains the concepts of surface tension and interfacial tension and goes through the measurements by using both optical and force tensiometer surface tension of a polymer in air but to the interfacial tension between a polymer and a condensed phase such as water or another polymer. Introduction to interfacial engineering; Colloidal materials: part I; Colloidal materials: part II; Colloidal materials: part III; Colloidal materials: part IV; Colloidal materials: part V; The measurement of the surface and interfacial tension can be done by using Sigma force tensiometer. an idealized surface between two immiscible fluids; e.g. oil-water, air-water, oil-air. Therefore, it makes more sense to define the surface energy, or interfacial The origins of interfacial tension are analogous. What is an interface? time curves different stages of the experiment can be identified) At the beginning, the ring is above It is clear that the interfacial energy will be proportional to the number of molecules at the surface. It is based on the force measurements of the interaction of a probe at the • surface tension and interfacial flows. The result is an interfacial energy per area that acts to resist the creation Therefore, the surface has excess Gibbs energy relative to the interior of the liquid. The fundamental surface properties in capillarity can be thought of as A further nomenclature choice must be made between surface tension and surface free energy. there is no surface tension between [4] Attension® I Surface and interfacial tension [Figure 5] From force vs. Surface tension is the excess energy per unit area (force per unit length; SI unit is Nm-1).
