Abstract

In order to derive the specific properties of polymer nanocomposites, we investigated the influence of the dispersibility of nanoparticles on dielectric property. Experiments were carried out for epoxy/alumina nanocomposites with the particle dispersion techniques using ultrasonic wave (USW) and centrifugal force (CF). In this paper, by controlling the application duration of ultrasonic wave, we investigated its influence on particle dispersion and dielectric permittivity. As the result, we verified quantitatively that the extension of the application duration of ultrasonic wave could improve dispersibility of nanoparticles and reduce relative permittivity of nanocomposites.
