Correlations between the interactions in magnetic dispersions and interparticle interaction fields in pigmented films

Rheological studies for a series of metal particle dispersions showed viscous flow at low particle loadings and an elastic network at high loadings. Magnetic remanence measurements on pigmented films prepared from these dispersions showed that the interparticle interaction field increased with increasing pigment loading and had a good correlation with values of Casson yield stress and storage modulus measured on the magnetic dispersions.
