Description

Low molecular weight charged molecules are known to change the rheological behaviour of oxide dispersions dramatically. Here the isomers of muconic acid were used to investigate the effect of molecular structure and solubility on the bulk properties of alumina dispersions and the nanoscale interactions between alumina surfaces. The surface forces in dispersions were characterised by yield stress while atomic force microscopy (AFM) was used to directly measure the force between a single alumina...[Show more]
