Interface Rotational Rheometry - Treatment of Data Measured Using BiCone Geometry

Popis výsledku v původním jazyce

Interfacial rheometry is of great interest nowadays. The quality of both liquid/air and liquid/liquid interfaces influences foaming, emulsification, fluid separation, etc. of a given system either in certain technologies, environment or in living organism. The quality of an interface can be described by (i) surface/interface tension, (ii) surface/interface Gibbs elasticity, which gives information about the resistance of the interface to change in size, and (iii) surface/interface viscoelastic properties, which describe the resistance of the interface to shear deformation. The viscoelastic properties can be measured e.g. by optical rheometry, needle rheometry or by rotational rheometers with sensors of either ring geometry or BiCone geometry. In the case of using rotational rheometers with BiCone geometry, the data treatment is not trivial because the total drag force is given by the sum of the interface and bulk contributions. This paper presents and discusses different ways of handling data measured with BiCone geometry.
