Rheological properties of hydrotalcite-like compounds/montmorillonite suspensions

The novel rheological properties of the hydrotalcite-like compound (HTlc)/sodium montmorillonite (MT) suspensions were investigated. The influence of the weight ratio of HTlc to MT (R) on the microstructure of the suspensions was examined emphatically. As increasing of R values, the structure strength increased gradually. Moreover, significant deviation from the Cox-Merz rule was observed in the HTlc/MT systems, which proved the formation of the network structure. The mechanism of “dispersion particles-steric network-dense network” was used to explain the complicated phenomena in these complex suspensions.
