Abstract
This paper appraises the usefulness of neutron diffraction and small angle scattering for determining the structure of dilute and concentrated sols. For monodisperse polystyrene latex, the particle size and density can be readily determined and an upper limit to density fluctuations within the colloid particle set. For the polystyrene latex peptized by the adsorption of laurate, the physical dimensions and packing density of the adsorbed phase can be determined. The effects of polydispersity for unpeptized and peptized graphite sols, and the effects of extreme particle anisotropy using sols of montmorillonite clay minerals have been studied.Keywords
