Microcomposites are a well known class of materials. The enhancement of polymer matrix properties can be explained by the classical mixing law. But if the inclusion size is decreased to reach the nanometric range, the improvement of properties is no more due to mixing effect but to the influence of interface of nanoparticles on the matrix. A new emerging class of materials is composites reinforced...
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...
Two kinds of electrodes showing different behaviour with respect to the impurity particles present in a dielectric fluid have been designed and built. Both electrodes have a uniform field region. The first kind is designed in order to avoid as far as possible the attraction of impurity particles into the test volume, whereas the second one is designed to the opposite aim. This is achieved by means...
