Abstract :
For the application of nanocomposite materials to solid insulator in electric power apparatus, we investigated the influence of the dispersibility of nanoparticles on dielectric property. Experiments were carried out in epoxy/alumina nanocomposites with the particle dispersion techniques using ultrasonic wave and centrifugal force. As the result, we verified the specific characteristics of dielectric permittivity in nanocomposites with good dispersibility.
