Capillary Forces in Suspensions: Rheological Features und Potential Applications

It has been found that in suspensions capillary forces play an essential role between the disperse phase and the continuous phase in respect of their rheological behavior. In this review it is shown, that the rheological behavior of a disperse phase, which is dispersed in a continuous phase, can be changed significantly by adding a small amount (< 1%) of a secondary liquid that is not mixable with the bulk phase. This effect now can be used to modify product properties specifically.
