| dc.description.abstract | Stearate intercalated layered double hydroxide was synthesized by reacting the corresponding carbonate form with a large excess of stearic acid. Thermal analysis, FTIR, XRD and SEMEDS characterization indicated the formation of a highly crystalline bilayer-intercalated product. The composition of the inorganic portion showed high variability in the Al:Mg atom ratio. This suggests that the crystals comprised stacks of randomly interstratified layers that varied in compositions from one close to magnesium stearate to one similar to aluminium distearate. The rheology of the jojoba oil suspensions containing this material showed strong shear thinning behaviour and also an anomalous temperature dependence. | en |
