Diglycidyl ether of bisphenol A (DGEBA) and diglycidyl ether of bisphenol F (DGEBF) reinforced with organo-montmorillonite clay nanoplatelets were investigated using anhydride- and amine-curing agents. The sonication technique was used to process epoxy/clay nanocomposites. The basal spacing of clay nanoplatelets was observed by wide-angle X-ray scattering (WAXS), small-angle X-ray scattering (SAXS) techniques, and transmission electron microscopy. It was found that the basal spacing of clay...
