Abstract

The dielectric properties of DGEBA/MDA/GN system under inhomoneous electric field were investigated. As GN contents increased, impact strength increased, but dielectric breakdown strength decreased. At $150^{\circ}C$, the dielectric breakdown strength decreased and uniformly maintained with the increment of distance between two electrodes. The life-time of epoxy resin increased with the decrement of applied voltage, but dielectric breakdown didn't occur below specific applied voltage.
