Abstract :
The thermo-mechanical and the electrical characterization of some nanocomposites prepared from bisphenolic epoxy resins and different nanoclays are presented. The study of the nanocomposites morphology revealed a good dispersion of the nanoclay in the epoxy polymer. The dynamic modulus was found to be higher for the nanocomposites irrespective of the nature of the adopted clay. The space charge accumulation was found to be significantly lower in the nanocomposites than inside the pure polymer. Short time AC dielectric breakdown strength measurement also showed an increase of the BD strength for all the nanocomposites.
