Interfacial Shear Rheometer
KSV NIMA Interfacial Shear Rheometer (ISR) is an advanced characterization instrument for studying the viscoelasticity of Langmuir films.
Overview
What you can study
Applications controlled by interfacial rheology, including:
Biological systems such as pulmonary lung surfactant and meibum. Their functionality is largely based on their flow on interphases under stress.
Emulsions and foams whose stability is vital for their functionality. Viscoelasticity of an interface can predict the stability of a complex fluid. Micelle/droplet fusion and fission are largely dependent on the interface viscoelasticity.
Oil and gas, cosmetics, food products, biophysics, pharmaceuticals, application areas where molecules at interfaces have desired flow properties, such as asphaltenes in oil and gas.
Langmuir monolayer structural studies, including:
Phase changes, as the viscoelasticity of the layer is strongly affected by the phase transition.
Surface reactions such as crosslinking in real time, as changes in molecular size and shape have typically a strong response in their rheological properties.
Aggregation and adsorption, as they typically change the viscoelasticity of the film.
Determination of optimal coating parameters prior to deposition, as the Langmuir-Blodgett coating is based on the flow of the molecules to the solid substrate.
