초록

In this paper, the electrical conduction, breakdown strength and dielectric properties were investigated in the interfaces of PET films. The volume resistivity and breakdown strength were decreased; especially the specimens with semiconductive layer showed the lowest breakdown strength. This decrease of electrical properties was appeared by increasing charge density in inhomogeneous layer of PET. The dielectric properties of PET did not show significant difference with PET/PET but the films with semiconductive interface layer showed the increase in capacitance and $tan\delta$ was affected by the PET rather than semiconductive layer. It is assumed that the variation of $tan\delta$ was affected by the dielectric polarization and the leakage current(charge).
