Effects of Colloidal Nanosilica on the Rheological Properties of Epoxy Resins Filled with Organoclay
The rheological properties of epoxy resins filled with organoclay and colloidal nanosilica were investigated by employing a parallel plate rheometer in flow mode at 25 °C. Shear thickening and shear thinning behaviors were observed in the epoxy resins filled with a mixture of organoclay
and colloidal nanosilica. Minima were observed in the relaxation time of the systems consisting of epoxy resins filled with organoclay and colloidal silica as the content of colloidal nanosilica was increased. It seems that the colloidal nanosilica increased the mobility of the filled epoxy
resins and reduced the interactions between the silicate layers in the systems.
