Foam stability refers to the ability of a foam to maintain its structure and resist collapse over time.
In this blog post, the most common interfacial shear rheology methods are reviewed.
Interfacial rheology studies the response of the interfacial layer to the external stimuli at air-liquid or liquid-liquid interfaces.
Interfacial shear rheology at the gas-liquid or liquid-liquid interface is relevant in a wide range of applications where foams and emulsions are used.
Interfacial rheology is a special branch of rheology that involves studying the unique two-dimensional systems formed at interfaces.
Demulsification is a process where emulsions are broken down, most typically by the addition of chemicals.
Emulsions are dispersed systems of two immiscible liquids such as oil and water. Interfacial rheology measurements predict emulsion stability.
Interfacial rheology studies the flow properties of the interfacial layer that is formed between two immiscible fluids, such as oil and water.
Rheology studies the flow and deformation of the fluid. Interfacial rheology studies the same for interfacial layers.
